New Order Copier – Handbuch

#1. Product overview

#1.1 What New Order Copier does

New Order Copier copies orders and positions from sources to targets:

• Sources (where orders come from):
  • MetaTrader 4 and MetaTrader 5 (netting and hedging accounts), through the expert advisor NewOrderCopier and the plugin tcCopierPlugin.dll.
  • Interactive Brokers TWS / IB Gateway logins (an IBKR account is watched; the copier never places, changes or cancels anything on a source login). This allows IB-to-IB copying, including orders placed by hand in TWS.
  • The Signal API: your own program, script, MetaTrader indicator/EA or a webhook sends JSON commands (place, modify, cancel, close) over WebSocket or HTTP POST.
  • Remote Copier: signals received from another New Order Copier (Client Mode).
• Targets (where orders are placed):
  • Interactive Brokers accounts through TWS or IB Gateway: single accounts, and advisor (FA) logins with their sub-accounts and FA allocation groups.
  • Client Mode groups: other New Order Copiers (your customers) that receive your signals.
• Routing (n:m): the Routing page is a matrix: one column per source, one row per target, one connector per source/target pair. Any source can be copied to any number of targets and any target can receive from any number of sources. No connector, or a connector switched off = nothing is copied on that pair.

#1.2 The program

• There is one program: NewOrderCopierService (Windows: NewOrderCopierService.exe). It runs either as a console (a window you start from the Start menu) or as a Windows service / Linux systemd service.
• It is operated only in the browser (the web frontend), by default at http://127.0.0.1:8743/.
• The old desktop program (NewOrderCopier.exe) no longer exists since v1000.704 (2026-11-02). An update removes it.
• Platforms: Windows 10 (1903+) / Windows 11 / Windows Server 2022+, 64-bit; Linux 64-bit with systemd. No macOS version.
• MetaTrader components (plugin and EAs) exist for Windows only. A MetaTrader on Windows can connect to a copier on another computer (including Linux) over the TLS Remote API port.
• Two web roles: Operator (may change everything) and Viewer (read only).
• User interface in 10 languages: English, Deutsch, Français, Español, Italiano, Русский, Nederlands, Português, 简体中文 (Simplified Chinese), 日本語. Traditional Chinese is not offered (falls back to English). Log files are always English.

#2. Features

#2.1 Sources in detail

#Common to every source

• Every source has a name (required for MetaTrader; optional for TWS and Signal API). Max 64 characters, unique (case-insensitive), no ', " or \. The name is only a label; renaming changes nothing else.
• Source menu (⋯ in the source column header): Edit source..., Activate source / Deactivate source, Suspend... / Resume, Open Log, Performance report..., Performance filter..., Delete source... (asks for Your password; orders already at the targets are not touched).
• Header colours: grey = inactive, blue = active but not connected, green = connected, purple striped = Blocked (performance filter refuses new entries), half-transparent yellow = suspended (pacing or by hand). An outlined DEMO mark appears when the broker reports a demo account (badge only, no effect on a source).

#MetaTrader 4 / MetaTrader 5 source

• The EA NewOrderCopier (in the Navigator under Experts > trade-commander > NewOrderCopier) shows an ident token in its panel (IDENT TOKEN, button Copy; also printed in the Experts log). Format: MT<4|5>-<account>-<broker>-<8 hex characters>.
• The source is created in the web frontend: Routing > New Source..., tab MetaTrader, Name, paste the Ident token, OK. Then press Connect in the EA panel.
• Only tokens created as a source by the operator can connect. An unknown token, or the token of a deactivated source, is refused and disconnected. Another MetaTrader account produces another token.
• Same computer: the EA connects to the Copy port (MetaTrader) (default 29496, 127.0.0.1). Another computer: the copier's Remote API port (default 29497, TLS only) plus the copier's certificate fingerprint in the EA input CopierFingerprint.
• Account kinds: MT4, MT5 netting, MT5 hedging.
• Magic number filter (Positive Magic #s / Negative Magic #s, comma-separated; the positive list wins; a leading # disables a list): MetaTrader 5 only. MT4 orders are not filtered by magic number.
• The EA panel has its own COPY FILTERS (Copy MKT orders only, Ignore TP / SL, Allowed symbols, Blocked symbols). They act inside MetaTrader: a filtered order never reaches the copier.
• What happens while the copier is not running is buffered by the EA and delivered on reconnect (see 2.8 "Restart and replay").
• Orders/positions commented NOC: (placed by a New Order Copier MetaTrader target) are not copied back.

#TWS / IB Gateway source (observer)

• Fields: Name (optional; default = master account), IP (default 127.0.0.1), Port (default 7496), Client ID (default 0), Master account (required; checked on every connect, mismatch = disconnected and switched off).
• Client ID:
  • 0 = sees every order of that TWS session, including orders entered by hand. This is the recommended setting for copying what you trade in TWS.
  • the Master API client ID set in TWS = meant to see everything the account does, whichever program placed it (this variant is not verified by the vendor; 0 is the tested choice).
  • any other number = only that client's own orders, i.e. nothing (a source places no orders).
• IP, Port and Client ID cannot be changed afterwards ("Endpoint not changed"): delete and recreate the source.
• What is copied:
  • Working LMT, STP, STP LMT orders → resting copies; a change → modify; a cancel → cancel.
  • MKT orders → copied as soon as TWS reports them Submitted, with the whole order size. The order type decides; a limit price that TWS reports beside a MKT order does not make it a limit order.
  • Other IBKR order types (TRAIL, REL, MIT, MOC, PEG, ...) are not copied (warning in the source log).
  • While TWS reports Inactive, Filled or PendingCancel nothing is sent; Cancelled is acted on.
  • Fill of a resting source order: the resting copy is left to fill by itself at its own price. Option TWS source: fill turns the copy into a market order (Settings > Copying, default off): the first fill turns the copy into a market order for its whole open size, once. Connectors with Copy position changes only copy the fill instead.
  • Bracket children are copied as their own orders and attached to the copy of their parent. A child waits up to 2 s for its parent; otherwise it is copied unattached (warning).
  • Iceberg / algo: display size scaled like the order (rounded, between 1 and the order size; 0 stays 0); algo strategy and parameters copied (a quantity parameter such as DarkIce display size is scaled). Entry orders only, never closes, stops or targets. A change is copied as a modify.
  • Copied attributes: side, quantity, type, limit/stop price, parent link, TIF, outside RTH, iceberg/algo. Other order fields are not carried.
  • Executions that TWS replays on connect are not copied. Copying starts after the login has reported its positions.
• Self-copy guard: a source at the same host:port as a target, or a source sharing an account with a target, is refused.
• Sizing 1:1 (one contract = one contract × connector Multiplier); no mapping table is needed. An optional IB-IB mapping table can redirect a contract and set a factor.
• A contract the copier has never seen is requested from TWS automatically (a working order waits up to 1.5 s for it).

#Signal API (your own program as a source)

• Create it in Add source > tab Signal API > Token (or paste a SIG-... token into the MetaTrader tab). The client generates and shows the token; the copier does not make it. Token rules: starts with SIG-, 8–63 characters, no spaces, quotes or backslash. Name optional (default = token). The MQL client shows SIG-MT5-<account>-<8hex>.
• Adding a Signal API source switches the Local API port on automatically.
• Transport:
  • Local API port (default 7788, 127.0.0.1 only): WebSocket, one JSON object per text frame, or POST /signal.
  • Remote API port (default 29497, TLS only): WebSocket path /signal and POST /signal; the client pins the certificate fingerprint.
  • A request carrying a browser Origin header is refused on these ports (a web page cannot reach them).
• Envelope fields: v (1), msg, id (echoed in the ack), ts.
• hello (first message of a WebSocket session): token (required), client, name. A wrong token → ack bad_token, connection closed. heartbeat is answered with heartbeat.
• POST /signal: token in the body, one message per request. HTTP 200 = ack in the body; 400 = bad_message; 401 = bad_token.
• Commands:
  • place: oid (max 64 characters, unique while live), symbol, side BUY|SELL, type MKT|LMT|STP|STPLMT, qty > 0, qty_unit lots|contracts (required, no default), price (LMT; limit of STPLMT), stop_price (STP; trigger of STPLMT), optional sl, tp, tif GTC|DAY|IOC|FOK (IOC/FOK only with MKT), comment (log/database only, never sent to the broker). A MKT place requires ts (ISO-8601 UTC) and ref_price (ask for BUY, bid for SELL).
  • modify: oid + only what changes: price, stop_price, qty (resting orders), sl, tp (null = remove). Symbol, side, type, qty_unit and tif cannot be modified (cancel and place again). For a filled market position only sl/tp can change.
  • cancel: oid – withdraws the resting order and closes what of it has filled.
  • close: oid or symbol (closes all live oids on it); optional qty (partial close, only by oid, only market positions); optional ref_price.
  • fill: oid, qty, price – recorded for the performance report only, never sent to a target.
  • position: symbol + vpos. An optional vpos on every instruction = the client's signed virtual position after it; it serves as the source's position report for Maintain Source Positions (it places nothing by itself).
• Sizing: lots = like a MetaTrader lot (mapping Conv. factor × connector Multiplier); contracts = connector factors only.
• Ack: {"v":1,"msg":"ack","id":...,"ok":...,"code":...}, once per message. ok=true means "received and well-formed", never "executed at the targets". Codes: bad_message, bad_token, source_inactive, unknown_type, oid_in_use, oid_unknown, not_modifiable, tif_not_restable. Per-target results (unmapped symbol, licence lock, broker refusal) are not sent back; they appear on Log > Copy Errors. There is no other return channel (no fills or positions are reported back).
• Stale market entries: a MKT place whose ts is older than 45 s is acknowledged but not sent (config.json /Signal/stale_entry_s, 0 = never; no UI).
• tif applies to the entry; its sl/tp legs are always GTC.
• Target-agnostic: a command for a target that cannot trade at that moment is dropped (not buffered); an entry missed there stays left out there. After a copier start, WebSocket signals are held up to 10 s while a routed target is still syncing (POST /signal never waits).
• The MetaTrader client library SignalApi.mqh and the demo EA SignalApiDemo (inputs InpHost 127.0.0.1, InpPort 7788, InpFingerprint, InpLots 0.10, InpSlPoints, InpTpPoints, InpConfirmAll, InpName) ship with the MetaTrader components.

#Remote Copier source (receiving Client Mode signals)

• Add source > Remote Copier > Access token (from your signal provider) > OK. The copier asks the sender which signals the token allows (Receive signals, all ticked). Each ticked signal becomes a source named <signal> (<sender>).
• The copier offers to fetch the sender's symbol tables; they arrive read-only (named HUB: ...).
• Signals the sender adds later are added automatically (with a message); a removed signal is reported, the source stays.
• Connection: TLS WebSocket, sender's key pinned by the token; a reconnect resumes from the current state. Nothing is copied until you switch on a connector of the received source.
• A received signal can never be forwarded to your own Client Mode groups.

#2.2 Targets in detail

#TWS / IB Gateway target

• New Target... / Edit target...: IP (default 127.0.0.1), Port (default 7497 = TWS paper; TWS live 7496, Gateway live 4001, Gateway paper 4002), Master account (required; verified on every connect: mismatch = disconnected, switched inactive, MASTER ACCOUNT MISMATCH in the log). A new target starts inactive.
• There is no client ID field for a target. The copier calculates the TWS API client ID on first save, stores it and never changes it (TWS lets a client modify/cancel only the orders it placed itself). It is never 0.
• Accounts of this login (display), Licensed accounts (see 5), Account Protection, Flatten when source is flat, links Account Information..., Open Log.
• Target menu: Edit target..., Activate target / Deactivate target (asks if positions/orders are open; they stay at the broker, unwatched), Maintain Source Positions..., Open Log, Delete target... (password; broker positions are not touched).

#Advisor (FA) logins

• One target = one TWS/Gateway login. Sub-account or FA group is chosen per connector (Allocation: Allocate to account | group, Account / group, Allocation method NetLiq / AvailableEquity / EqualQuantity / PctChange, Percentage (PctChange)). Empty = no allocation, TWS decides.
• FA groups are read again every 30 minutes and on every connect (TWS does not report group edits). Reconnect the target if a group change must apply immediately.
• Orders > IB Account shows values per sub-account; Update FA Info reloads FA settings.

#Client Mode group (sending your signals to other copiers)

• Add target > Client Mode (other copiers) > Group name (e.g. Premium). Shown as a row => <group>. A click on the tile toggles the connector directly. See 2.9.

#MetaTrader terminal as target

• Exists but is frozen: it is not offered for new targets in the standard configuration and is not supported for new customers.

#2.3 Order types

• A resting (pending) order keeps its type at the target: a stop stays a stop.
• An order whose type did not arrive, or a stop limit without its limit price, is not sent.
• A cancelled pending order is cancelled at the target, never turned into a market close.

#2.4 Stop loss, take profit and brackets

• A pending order's own SL/TP is placed together with it as a native IBKR bracket (parent + children, released together).
• SL/TP changes are sent as modifies; only what changed is sent; a modify that changes nothing is not sent.
• Net bracket (MT4 and MT5 hedging → IBKR): IBKR holds one net position per contract, so the copier keeps one stop and one target per contract on the closing side of the net position, sized to the net, priced from the dominant position. Net zero = no protective orders. A stop is never left working without a position under it (it would open a position).
• Removed SL or TP while the other leg lives: on IBKR, cancelling one leg cancels its partner. So the copier parks the removed leg far from the market (0.5 % by default, config.json /Routing/park_removed_pct, max 0.9) instead of cancelling it. Log reason sl parked / tp parked.
• A filled copy of a resting source order is never placed again; its SL/TP keep following the source order, sized by what the target holds.
• With Ignore stop loss / take profit (see 4) no protective orders are placed; closes are still copied.

#2.5 Closes, partial closes, reversals

• A close is sized from the copier's own fills for that position at that target, never from the account and never more than the target holds.
• A partial close never exceeds what this target holds on that side; a target that holds nothing sends nothing.
• Close-by (two opposite MT positions closed against each other): no order is placed; the net bracket is adjusted.
• A closed position stays closed: a late modify or close message for a position the source has already closed is ignored (only a new open brings it back).
• A cancel at the source closes what its copy had already filled (intended).
• Netting reversal (MT5 netting, long → short in one deal): with Copy netting reversals on (default), copied as one order of old + new size, old stop/target cancelled. Off = not copied; the target keeps its old position. (MT5 netting is not yet verified on a live account.)

#2.6 Time in force and outside RTH

Order of precedence:

1. An order default assigned in the mapping row (or basket leg) – overrides the source.
2. The source order's own value (a TWS source states TIF and outside RTH, also for stop/target).
3. The contract's TIF; outside RTH off.

• A stop/target whose source states no TIF (MetaTrader SL/TP) is always GTC.
• A source GTD order counts as "TIF not stated" (the date is not carried) → rule 3.
• Built-in per-security-type defaults are never applied.
• An order default only sets TIF and outside RTH; never the order type, algo or allocation.

#2.7 Sizing

Per order and connector:

MetaTrader / Signal API (lots):  lots × Conv. factor (mapping row) × Multiplier × balance factor (if on)
Signal API (contracts):          qty × Multiplier × balance factor (if on)
TWS source:                      quantity × (IB-IB row factor, else 1) × Multiplier × balance factor (if on)

• Only the connector scales a copy. Sources and targets have no size setting.
• Connector Multiplier: default 1, must be > 0 (0 or negative is refused: "The multiplier must be greater than 0.").
• Use balance factor: also multiplies by target net liquidation / source balance (replicate risk). Applied only while both values are known; otherwise the order is sized without it and a warning is logged. Default off. (The dialog field Balance factor (live) currently always shows "unknown - both ends must be connected".)
• Mapping Conv. factor = IBKR units per source lot. A negative factor = fixed size in units, not scaled by multiplier or balance factor. 0 is refused.
• Rounding: to the nearest whole unit, never below 1 for an order that has a size. (A result of zero is recorded as "size came out zero".)
• Example: 1.00 lot XAUUSD, factor 10, multiplier 0.5 → 5 contracts.

#2.8 Symbol mapping

• Page Symbol Mapping (side bar Copy). A mapping table (mapping set) is a named list of rows: source symbol → IBKR contract + Conv. factor (+ optional Order default). Contract and factor always come from the same row.
• Kinds of table: source side Symbol (Generic, MT4, MT5) or IBKR (InteractiveBrokers), target side likewise. S-IB (symbol → IBKR contract) is used for MetaTrader and Signal API sources; IB-IB (contract → contract) for TWS sources.
• Columns: Source symbol, Symbol (local), Underlying, Type, Curr., Exchange, Expiry, Right, Strike, ConId, Conv. factor, Invert, Order default.
• A connector references a table (Mapping table in the connector dialog). Several connectors may share one table; a change reaches all of them and asks first; a table in use cannot be deleted. Duplicate... makes an independent copy. Use as default = preset for new connectors.
• MetaTrader / Signal API source: no table, or symbol not in the table → that connector copies NOTHING (red ERROR row on Log > Copy Errors, red Attention banner). A TWS source copies 1:1 without a table.
• Tools: Add symbol..., Contract search (needs a connected TWS; types CASH, FUT, FOP, IND, OPT, STK, CMDTY, CFD, IOPT, FUND, CRYPTO), Remove selected, Import... / Export (CSV with ;), Import contract database from an older version..., Order defaults, Baskets.
• A symbol may appear once per table; a contract may be the target of one symbol per table.
• Order defaults: Name, Sec type, TIF (DAY, GTC, IOC, FOK, GTD, OPG), Type, Also fill outside regular trading hours, Algo. Only TIF and outside RTH are applied to copies.
• Baskets: one source symbol → several broker orders (legs). Kinds: "IBKR basket - a different contract per leg" / "Single symbol - the same contract in every leg". Leg fields: Contract, Action (BUY - buys when the source BUYS / SELL - sells when the source BUYS), Conversion factor, Default size, Order default. Leg size = source lots × mapping factor × conversion factor × default size; negative = fixed units. Leg actions are calibrated to a buying source order; on a SELL the whole basket turns over.
• Invert is stored but not applied (a BUY does not become a SELL).

#2.9 Client Mode (send signals to other copiers)

• Groups are target rows (e.g. Premium, Free trial); the connector source → group decides what the group receives.
• Requirements: Remote API port on (TLS), Sender name and Hub address set (Settings > Signal Output), port opened in router/firewall.
• Customers (side bar Client Customers): New customer... (Name, E-mail, Group, Language, Order number, Send the token by mail), Change group... (= new token), Replace token..., On / Off, Delete. A token binds one receiving copier to one group and contains hub address, port and certificate fingerprint. Without mail the token is shown once ("Access token - copy it now"). The copier keeps no readable copy of a token.
• The receiver pastes the token into New Source > Remote Copier.
• Draining: a source taken out of a group still sends reducing events (closes, SL/TP) there until flat.
• Subscriptions by file: your shop/script writes one JSON file per order into the Subscription folder ({"action":"subscribe"|"cancel","order_id","email","group","name","language"}). The copier creates the token, mails it through your SMTP server, and moves the file to done or failed with a .result.json. An unknown group name creates the group (active, no connector). A token exists only if its mail was sent.
• Licence: a group counts as one target account while at least one of its copiers is connected. Receivers license their own targets.

#2.10 Copy options and filters (overview)

There are no hidden switches: source, target and connector are the on/off switches.

#2.11 Safety functions

#Emergency Stop

Side bar (foot) Emergency Stop, or console command emstop. After the confirmation I understand that this closes positions. (+ Your password if enabled):

1. every connector is switched off (persisted),
2. sources are stopped,
3. every working order is cancelled on every target,
4. every position is closed on every target – including positions opened by hand.

Targets that are not connected are reported ("NOT connected - cannot be touched"), never skipped silently. Operators only.

#Account protection (per target)

• In the target dialog (Account Protection) or for all targets via Account Protection (all)...: Enabled (default off), Drawdown % (default 10, between 0 and 100 exclusive), Watched account (master account or All = sum of the target's accounts), Trail (reference follows new highs), Threshold (stop level) preview.
• Arms at the first complete account reading. Fires when net liquidation is at or below the stop on two complete readings in a row (a reading below half the reference is treated as a data error). Then it cancels the orders and closes the positions of that target. Fires once per run; connectors stay on.
• Has not yet fired against a live broker in vendor tests – test it on a paper account.

#Maintain Source Positions (manual reconciliation)

• Toolbar Maintain Source Positions (all routes)..., target menu, or connector dialog. Always asks for confirmation and password.
• Cancels copies of pending orders the source no longer has, then closes (market) positions this copier opened for that source on symbols the source reports flat (their SL/TP cancelled first).
• Never opens a position, never touches manual positions or other sources' positions; only active connectors.
• A MetaTrader EA is asked for a fresh position report first (needs a current EA); a TWS source is reconciled from its login's report (only when synced); a Signal API source from its vpos.
• Never runs by itself – nothing is reconciled automatically when an EA connects.

#Pacing / Suspend

• Default: more than 10 openings and changes per 1 s per source = pacing violation. Counted: market entries, new pending orders, additions, reversals, moved pending orders, SL/TP changes. Not counted: closes, partial closes, cancels.
• A violation suspends the source for every target and group: new entries are excluded, changes are held (the last one per order is sent on release), additions are dropped, closes/partial closes/cancels pass, resting entries are withdrawn (setting Withdraw resting entries, default on) and never copied again. Released automatically after 10 s within the limit.
• Suspend... / Resume by hand (source menu or Edit Source): same state, survives a restart, ends only with Resume. (The former "Block source" function was replaced by this.)

#Boarding after a (re)connect

Trade messages of a freshly connected MetaTrader source are held until the EA has reported its current state (max 10 s, then released anyway).

#Restart and replay

• The EA delivers buffered events on reconnect. A position opened and closed entirely while the copier was down is not copied (Copy Errors: "opened and closed while the copier was down").
• If the terminal was restarted too, its buffer is lost: use Maintain Source Positions.
• While no target can trade, held MetaTrader market entries are dropped after Stale entry timeout (s) (45 s), together with their later close; pending orders, closes, cancels, partial closes and SL/TP changes never expire.

#Confirmations and passwords

Settings > Confirmations: Password to close positions and for the Emergency Stop (default on) and the Ask before ... questions (default on).

#2.12 Monitoring and diagnostics

• Control page (opens after login): tiles Sources live, Targets live, Connectors live, Copier time (median) (signal in → sent by this program), Target round trip (sent → first broker answer); Copy activity (Today, This week, chart last 4 hours · per 5 minutes); Why nothing arrived: Not sent by the copier (amber) and Refused by the broker (red), never merged; licence state; Server ports; Data folder.
• Routing matrix: connector tiles: dashed + New connector (none), grey OFF/ON (off, or source off), blue ON (active, not live), green live. Capital status lines: SOURCE INACTIVE, CONNECTOR DISABLED, SOURCE BLOCKED - no new entries, BOTH ENDS OFFLINE, SOURCE NOT CONNECTED, TARGET NOT CONNECTED, TARGET LOCKED BY LICENSE - no new entries. Counts per tile (today): grey copied, red refused, amber not sent; a click opens the list. A licence-locked target header is red striped ("Connected · license lock").
• Orders pages: Pending Orders (per-order Cancel), Executions (fills, Costs Diff = slippage vs source price), Positions (Close selected, Close all – market orders, also manual positions), IB Account (NLV, margin, sub-accounts, currency balances).
• Log page tabs: Main Log, Copy Errors (NOT SENT amber / ERROR red for unmapped symbol / REFUSED red / BROKER NOTE), Orders (order journal: one row per source action – INITIAL, PLACE, CANCEL, BRACKET, PARTIAL, REVERSE, CLOSE, CLOSE-BY, RECONCILE, REFUSED – with three latencies and a step timeline), Log files (every log file with filters and automatic Findings), Not copied / Refused.
• Order trace (Trace this order... / Trace An Order...): a self-contained HTML page following one source order through every target.
• Support extract (Write support extract...): one ZIP per order (trace, matching log lines, environment). See 7.9.

#2.13 Reports and AI reading (Pro version)

• Require the licence option Pro version ("performance reports, Sigma report, Publish, AI reading"). Without it: Pro version required; copying is unaffected. The Performance filter... does not need Pro. Operators only.
• Performance report (per source, at source prices, also for signals that were never copied): Net, Profit factor, Win rate, Max drawdown, Expectancy, Unpriced; summary by side; virtual equity in R; breakdown by symbol / hour / weekday / month; Still open; a MetaTrader-tester-style block; trade list CSV. "-" = not measurable (e.g. equity drawdowns, MFE/MAE – no market data).
• Σ-Report: all sources in R units; score = mean(R) × √n / stdev(R) (fewer than 10 trades = unrated); long vs short; weekday × hour; What the copies actually earned (from own broker fills).
• Publish...: chosen sources under public names, without account numbers: sigma_report.html + four PNGs (1200×630, 1920×1080, 1080×1350, 1080×1920); English or German; the disclaimer is on every file.
• Performance filter (per source rule, JSON): window, minimum trades, thresholds with hysteresis for profit factor, relative drawdown, loss streak; optional allow/deny by symbol, hours, weekdays. Works only while Settings > Copying > Performance entry filter is on.
• AI reading: advisory only, never acts; off by default. Providers: Local (this machine) (OpenAI-compatible endpoint such as Ollama or LM Studio), OpenRouter, OpenAI, Anthropic, Google Gemini, Grok (x.ai). Sends a digest of figures, never the page; names and money are always removed for internet providers; consent asked once per run with the text shown; API key stored encrypted.

#3. Installation and first start

#3.1 Windows

Requirements: 64-bit Windows 10 version 1903 or later, Windows 11, Windows Server 2022 or later. Windows Server 2016 and 2019 are not supported. Administrator rights for the setup.

Setup file: setup_NewOrderCopier_<version>.exe (code-signed). Wizard languages: English, German.

Steps:

1. Run the setup, accept the licence agreement (EULA; the liability exclusion is its section 7).
2. Select Components (both ticked by default):
   • Console with web frontend – started from the Start menu in a console window; copies while that window is open. For a trading PC with MetaTrader on it.
   • Windows service with web frontend – runs in the background, also without a logged-in user. For a server / VPS. Both install the same program NewOrderCopierService.exe.
3. Tasks:
   • Install the MetaTrader components now (MetaTrader must be closed) (ticked by default). An optional page Additional MetaTrader folder lets you name the root folder of a portable MetaTrader.
   • Start the Windows service now and show the setup code of its web frontend (service component only).
4. Finished page: Open the web frontend in the browser (if the service was started; the setup code is shown in a copyable field) or Start the copier now (console with web frontend).

Install folder: fixed, C:\Program Files\trade-commander.com\NewOrderCopier (cannot be chosen). Data folder: C:\ProgramData\trade-commander.com\NewOrderCopier – one folder shared by console and service (settings, databases, licence key, users, logs). Start menu: New Order Copier (web frontend) (console), New Order Copier (web frontend of the service) (opens http://127.0.0.1:8743/; always port 8743), Uninstall New Order Copier. No desktop icon.

Windows service:

Only one copier per Windows machine: console and service exclude each other. A second one says "New Order Copier already running" and ends.

Update: run the newer setup over the installed one. A running service is stopped first. The data folder is never touched (settings, order database, licence, users are kept). Start the service again afterwards (the setup task can do it). In MetaTrader, remove the EA from the chart and attach it again (MetaTrader does not reload a replaced EA file). An update from an older version deletes the old desktop program.

Update from a version before 1000.712: the old per-user data folder %LOCALAPPDATA%\trade-commander.com\NewOrderCopier is taken over once (without logs). If the service already had its own configuration, the one used last is kept and the other is moved to C:\ProgramData\trade-commander.com\NewOrderCopier.service-<date-time>. Nothing is merged or deleted.

Uninstall: Windows Settings > Apps > New Order Copier > Uninstall (or the Start menu entry). The service is removed. Not removed: the data folder (delete by hand only if it is really no longer needed – it contains the order database) and the MetaTrader components inside the terminals (remove them with Setup > Install MetaTrader components... or mci uninstall).

The setup creates no Windows firewall rule.

#3.2 MetaTrader components (Windows)

A wrong bitness fails exactly like a missing file (cannot load 'tcCopierPlugin.dll' [126]). Do not copy the files by hand. Three ways to install:

1. The setup task (MetaTrader must be closed).
2. Web frontend: Setup > Install MetaTrader components... (Extra start folder, Scan, tick the terminals, Dry run, Install into / Remove from). Works on the copier's computer. When the copier runs as Windows service, the scan sees the service account's folders, not your user's – use the setup or mci.exe instead.
3. mci.exe in the install folder (run as the Windows user who owns the MetaTrader):

   mci scan [--root <folder>]... [--depth <n>] [--verbose]
   mci install --components <folder> [--root <folder>] [--dry-run] [--unconfirmed]
   mci uninstall [--root <folder>] [--dry-run] [--unconfirmed]
   "C:\Program Files\trade-commander.com\NewOrderCopier\mci.exe" install --components "C:\Program Files\trade-commander.com\NewOrderCopier\components" --root D:\trading

Searched by default: %APPDATA%\MetaQuotes\Terminal and both Program Files trees (depth 6). Portable terminals only via --root. Each terminal gets installed_components.txt (do not edit).

In MetaTrader: Tools > Options > Expert Advisors > Allow DLL imports must be on (also in the EA's own dialog). Attach NewOrderCopier to one chart per account.

EA inputs (MT5 NewOrderCopier): debug_to_expert_log (false, "Write debug information to experts log"), dll_log_level (-1, "Plugin loglevel (-1=auto,0 = system,3=normal,6=highest)"), server_timer_seconds (1), bridge_poll_ms (25, "Bridge poll interval (ms)"), CopierFingerprint ("", "Copier certificate fingerprint (remote copier only)"). EA inputs (MT4 NewOrderCopier): poll_interval_ms (10, "Order detection interval in ms"), bridge_read_ms (10), debug_to_expert_log (false), i_dll_log_level (-1), CopierFingerprint (""). EA panel: Copier IP (default 127.0.0.1), Copy Port (default 29496), COPY FILTERS (Copy MKT orders only, Ignore TP / SL, Allowed symbols, Blocked symbols), IDENT TOKEN + Copy, Connect / Disconnect. Panel title IB Order Copy v<n> - Connected|Disconnected.

Connection procedure:

1. Attach the EA, press Copy in the panel (token to clipboard).
2. Web: Routing > New Source..., tab MetaTrader, Name, paste Ident token, OK.
3. EA panel: Connect. Panel title shows Connected; source header turns green.

MetaTrader on another computer: in the copier switch on Remote API port (Settings > Connection and routing), copy Certificate SHA-256. In the EA: Copier IP = copier's address, Copy Port = the Remote API port (29497), input CopierFingerprint = the fingerprint. Open the port in firewall/router.

#3.3 Linux

Requirements: 64-bit x86 (amd64), systemd, glibc 2.38 or newer and libstdc++ 13 (e.g. Ubuntu 24.04, Debian 13, Fedora 39). Built on Ubuntu 24.04. No MetaTrader components on Linux (a Linux copier copies from TWS/Gateway, the Signal API, other copiers, and from MetaTrader on a Windows PC over the Remote API port).

Packages:

No GPG signature.

What the installation does: program in /opt/newordercopier, system user/group newordercopier, data folder /var/lib/newordercopier (mode 0700), web port in /etc/newordercopier.conf (NOC_WEB_PORT, default 8743; if busy, the next free port up to +100), service newordercopier.service enabled and started (also at boot), menu entry New Order Copier (opens the web frontend). At the end it prints:

New Order Copier runs as the service newordercopier.service.
  Web frontend:  http://127.0.0.1:<port>/   (menu: New Order Copier)
  Setup code:    <12 hex characters>   - create the first user with it, then accept the liability exclusion
  Log:           journalctl -u newordercopier -f

install.sh options:

sudo ./install.sh                                  # from the unpacked tarball: install, set up, start
sudo ./install.sh --port 8750                      # same, with another web port
sudo /opt/newordercopier/install.sh --port 8750    # later: change the web port (tarball or .deb)
sudo /opt/newordercopier/install.sh --uninstall    # remove (tarball installation only; data kept)
./install.sh --help

The port must be 1024–65535; an explicitly given busy port stops the installation.

Daily commands: systemctl status newordercopier, sudo systemctl stop|start newordercopier, journalctl -u newordercopier -f, setup code again: sudo cat /var/lib/newordercopier/config/web_setup_code.txt.

Update: install the newer package the same way (sudo apt install ./<new .deb> or unpack the new tarball and run sudo ./install.sh). A service you disabled stays disabled (sudo systemctl enable --now newordercopier). Uninstall: .deb: sudo apt remove newordercopier-service (purge removes only /etc/newordercopier.conf). Tarball: sudo /opt/newordercopier/install.sh --uninstall. /var/lib/newordercopier (incl. the order database) and the user newordercopier are always kept.

Console on Linux: running /opt/newordercopier/NewOrderCopierService by hand as a normal user without --datadir uses a separate installation (~/.local/share/NewOrderCopier, ~/.config/NewOrderCopier, ~/.local/state/NewOrderCopier) with its own settings, users, licence and order database. Warning: on Linux the single-instance lock is per data folder, so a console and the service CAN run at the same time and would copy every order twice. Run only one.

Remote access on Linux: the service unit binds the web frontend to 127.0.0.1 (command line overrides config.json). Use an SSH tunnel (see 3.5).

#3.4 First start and the setup code

1. Start the copier (console: Start menu; service: sc start NewOrderCopier / it runs after the Linux install). The console prints New Order Copier Service v<version> Build <build> and opens the browser.
2. Open http://127.0.0.1:8743/ (default).
3. Create the first operator with the one-time setup code (12 hex characters). Where to find it:
   • Console: printed in the console window (and in the log).
   • Windows service: file C:\ProgramData\trade-commander.com\NewOrderCopier\config\web_setup_code.txt (readable by administrators; also shown on the setup's Finished page if the service was started there).
   • Linux: printed by install.sh; file /var/lib/newordercopier/config/web_setup_code.txt. The code survives a restart and is deleted when the first user exists. There is no default user or password.
4. Fields: Setup code, User, Password, Password again → Create and log in. User name 1–32 characters (letters, digits, ., _, -); password at least 8 characters. The first user is always an operator.
5. Accept the liability exclusion (operator, tick + password again). Until then nothing is copied (the console status line shows copier NOT started (liability exclusion)). It is accepted once per data folder and again after a new program version or a text change. Alternative: start with --accept-disclaimer.
6. Enter the licence key (Info > License...), or use demo accounts without a key (see 5).
7. Create targets (New Target...), sources (New Source...), symbol mapping tables, and switch connectors on.

Sessions: logout after inactivity 30 min by default (Users > User management, Log out after inactivity (minutes), 5–720); only clicks/key presses count as activity; absolute limit 12 h. A copier restart logs everyone out. 5 failed logins within 5 minutes from one address → "too many failed logins - wait five minutes".

Users: Users menu: User management (operators: add user, role Viewer / Operator, New password..., delete; the last operator cannot be deleted or demoted; every change asks for your own password), Change password, Audit log (operators; file log/web_audit.log).

Lost password:

• Another operator sets a new one: Users > User management > New password....
• Console: command passwd <user> sets a random 12-character password and shows it once.
• Windows service with no other operator: stop the service, start the console (it uses the same data folder), run passwd <user>, exit, start the service again. If this does not work, contact support.

#3.5 Web frontend address and remote access

• Default: http://127.0.0.1:8743/ – reachable from the same computer only.
• Change port/address: config.json /Web/port, /Web/bind, or command line --web-port, --web-bind (next start). Linux: sudo /opt/newordercopier/install.sh --port <p>.
• Any address other than loopback is served as HTTPS only, with the installation's own certificate (the browser warns once). 0.0.0.0 = all addresses.
• Recommended remote access: SSH tunnel ssh -L 8743:127.0.0.1:8743 <user>@<server>, then open http://127.0.0.1:8743/ locally, or a VPN.
• If the copier is updated while a browser tab is open: "This page still runs the old version - reload it." → press Reload.

#3.6 Command line of NewOrderCopierService

Exit codes: 0 normal · 1 could not start (data folder, licence, core) · 2 liability exclusion not accepted · 3 web frontend could not start (port taken/invalid) · 64 unknown option · 75 another copier is already running.

Console commands (interactive console only, not in a service): clear errors, emstop (asks; only YES executes), errors, exit (quit), gui (reopen the browser), help (?), passwd <user>, positions, report, routes, signals, sources, status, targets, users, version, warnings. Ctrl+C stops the copier; copy text with Shift + mouse.

#3.7 Data folder

Windows permissions: SYSTEM and Administrators full control; NetworkService and the Windows user who ran the setup may modify; inheritance off. They are set again on every start.

Moving to a new PC / backup: there is no built-in backup or move function. Facts:

• Stop the copier cleanly before copying (this also releases its licence units).
• On Windows the licence key file cannot be decrypted on another PC – enter the key again on the new PC.
• A copied data folder is treated as a new installation (new installation ID); existing targets keep their stored client IDs.
• Never run the old and the new copier at the same time against the same accounts.

#4. Configuration reference

General rules:

• Settings page: side bar System > Settings. No OK button: a switch/list applies on change; a number/text applies with Save or Enter. If a number was out of range the banner says "saved as N (the allowed value)". Viewers see everything read-only.
• Most settings take effect at once; exceptions are marked (next start).
• Edit config.json by hand only while the copier is stopped – a running copier writes its own copy back at shutdown and overwrites hand edits.

#4.1 Settings > Copying

#4.2 Settings > Signal Output (Client Mode sender)

#4.3 Settings > Subscriptions

#4.4 Settings > Mail (SMTP for token mails)

#4.5 Settings > Connection and routing

Each port shows its state: open / off / FAILED - see the log. The web frontend's own port is not affected by these switches.

#4.6 Settings > Log files

#4.7 Settings > AI reading

#4.8 Settings > Confirmations

The Emergency Stop and Maintain Source Positions always ask.

#4.9 Source dialog (New Source / Edit Source)

#4.10 Target dialog (New Target / Edit Target)

#4.11 Connector dialog (double-click a matrix tile / Edit connector...)

#4.12 Per-browser preferences

#4.13 config.json-only settings (no UI)

Edit only while the copier is stopped.

#5. Licensing

#5.1 Activation

• Web: Info > License... → page Licence: paste the key from the purchase e-mail, press Activate (operators only). Alternatively start once with --licensekey <key>.
• The key is checked online against https://license.trade-commander.com (outgoing HTTPS must be allowed). It is stored only after the server accepted it; a refused key is not stored and a previously stored key stays.
• The key is stored in the data folder (config\license.dat), shared by console and service; on Windows it is encrypted for this machine.
• The licence is bound to the machine (machine ID).
• The licence page shows the key masked (last four characters) and the Digistore24 Order ID – support asks for it first.
• The licence is refreshed in the background. If the server cannot be reached, the copier stays licensed during an offline tolerance granted per licence by the server (shown on the page as "Last successful check ... (offline tolerance N h)").

#5.2 What counts: target accounts

• 1 unit = 1 target account. A TWS/Gateway login managing several accounts (FA) counts once per account.
• Only connected targets count. Sources never count.
• Targets are licensed in connect order, first fit; a target is licensed whole or not at all. Which target is locked can therefore differ from start to start.
• With Licensed accounts set on a target, only those accounts count, and no new entry reaches another account of that login (directly or through an FA group; an FA group with an unlicensed or unknown member is refused).
• A Client Mode group = 1 unit while at least one of its copiers is connected.
• A running copier always holds at least one unit on the licence server. The server adds up the units of all running installations of the same key.
• A locked or unlicensed live target receives no NEW entries. Stop/target changes, modifies, cancels, partial closes, closes, account protection and the Emergency Stop continue. A position that missed a target because of the lock stays left out there for its whole life, also after the licence is fixed.
• Control page: e.g. "Licensed: 2 of 3 target account(s) in use".

#5.3 Demo accounts and trial

• Demo targets are free: a target whose broker reports every account as demo (IBKR paper accounts starting with DU or DF, MetaTrader demo) is served with or without a licence and never counts as a unit. An account that cannot be classified counts as live.
• Without a licence key the copier copies new entries to demo targets only (free trial on paper accounts). Title bar: DEMO MODE - demo accounts only, no license key (Info > License...).
• Trial licences work like a bought licence until their end day; shown in turquoise as Licensed - trial, "Trial - N days left (until YYYY-MM-DD)" / "Trial - ends today". A trial ends without grace period.

#5.4 Editions

• One licence product (NewOrderCopier) for all editions. The Pro version adds performance reports, Σ-Report, Publish and AI reading. Without Pro: "Pro version required" on those pages; copying is unaffected; the licence page lists the feature as "not included in this license".
• A key of another trade-commander product is refused: "This license key belongs to a different product."

#5.5 Licence states

#5.6 Transfer to a new PC

• There is no "deactivate" button. Procedure: close the copier cleanly on the old PC (this releases its activation and units on the licence server), install on the new PC, enter the key again (on Windows the key file of the old PC cannot be used).
• After a crash, units are released when the lease expires (at least 90 seconds).
• How many machines a licence may use is set per licence on the server. If the new PC reports "This license is already active on the maximum number of machines.", contact support with the Order ID.

#6. Error messages and log lines

Log line format: <weekday> <date> <time>|<severity>|<function>|<thread>|<message>. Default log level is warning. main.log is complete only after a clean shutdown.

#6.1 "Not sent" reasons (Log > Copy Errors, amber NOT SENT; Control page Not sent by the copier)

Row format: NOT copied - <label> (<code>)[: <detail>]. <explanation>. Nothing in this record is replayed later.

Related source-log lines:

• [STACKED COMMAND DROPPED] ticket=<n> trans=<n> reason=market entry older than the configured timeout – a held market entry exceeded Stale entry timeout (s) while no target could trade.
• [STACKED COMMAND DROPPED] ... reason=entry expired - close/change would open a reverse position – the close/change of such a dropped entry (intended).
• [STACKED COMMANDS REPLAYED] forwarded=<n> – held messages sent after a target became ready.

#6.2 Refused by the broker (Copy Errors, red REFUSED)

#6.3 Licence messages

#6.4 Web frontend, console and start-up

#6.5 Connection log lines (TWS / IB Gateway)

#6.6 Order path log lines

#6.7 Copy port, EA registration, Signal API

#6.8 MetaTrader EA and plugin messages (Experts / Journal tab)

#6.9 IBKR message codes

Severity: error = error line, counted, row in Refused; warning = warning line only; info = not written. A code unknown to the copier is treated as error and shown as "not in IBKR's list". The copier explains codes only with IBKR's own text: <https://www.interactivebrokers.com/docs/tws-api/doc/error-handling/error-codes>;

#7. Troubleshooting and FAQ

#7.1 TWS / IB Gateway API settings

In TWS: Edit > Global Configuration > API > Settings. In IB Gateway: Configure > Settings > API > Settings.

• The copier reconnects by itself (first after 5 s, then doubling up to 30 s). An outage is logged once, then every 15 minutes, and once on recovery.
• After every connect the master account is verified (see MASTER ACCOUNT MISMATCH).
• FA logins: enter the advisor's master account; choose sub-account or group per connector.

#7.2 Client IDs

• Targets have no client ID field. The ID is calculated on first save from the master account and the installation, stored and never changed (a TWS client can only modify/cancel its own orders). It is never 0.
• TWS source: Client ID 0 (sees the session including manual orders) or the Master API client ID.
• Error 326 / "TWS not reachable ... may still hold the API client id": another program uses the same ID – typically a second copier (e.g. a copied data folder started on another PC) or a copier killed without closing. Close it or restart TWS.
• "Target A and target B use the SAME API client id": send a support extract to support.

#7.3 MetaTrader

• cannot load 'tcCopierPlugin.dll' [126]: wrong bitness or missing plugin – reinstall the components (MetaTrader closed).
• DLL message: enable Allow DLL imports, attach the EA again.
• After an update the old EA keeps running: remove it from the chart and attach it again (or restart MetaTrader).
• The installer reports a file in use: close every MetaTrader and install again.
• IDENT TOKEN red: create the source with exactly this token, press Connect. Another account = another token.
• EA stays Disconnected: EA Copy Port = Settings Copy port (MetaTrader) (29496), Copy port on, state open; the copier must be running.
• The source EA only needs Allow DLL imports; it does not place trades.
• One chart per account.
• MT4 orders are not filtered by magic number; MT5 orders are.
• The EA's own COPY FILTERS stop orders before they reach the copier.

#7.4 "Nothing is copied" – checklist

1. Is the liability exclusion accepted? (Only an operator can accept it; until then nothing is copied.)
2. Routing matrix: source header green, target row green, connector tile green live.
3. Log > Copy Errors: read the reason (6.1) – most common: no connector, connector switched off, symbol not in the mapping (a MetaTrader → IBKR connector without a mapping row copies nothing), magic number blocked, the license does not cover this target, new entries are switched off.
4. No licence key: only demo targets (DU/DF paper accounts) receive new entries (DEMO MODE in the title).
5. Source suspended (yellow header): pacing violation (more than 10 openings/changes per second) – released automatically after 10 s calm; a manual Suspend needs Resume.
6. Order sent but no broker answer: it is usually untransmitted in TWS – check TWS.
7. Was a market entry held because no target could trade? It is dropped after 45 s (Stale entry timeout (s)).
8. A position opened before the connector was switched on is not copied afterwards; there is no automatic synchronisation.

#7.5 Ports and firewall

• The setup creates no firewall rule; opening a port (e.g. the Remote API port for Client Mode) is your decision.
• Browsers cannot reach the trading ports (requests with an Origin header are refused).
• Ports are bound exclusively; a second program cannot use the same port.
• The copier contacts nothing else on its own (no auto-update). An AI provider and an SMTP server are contacted only if you set them up.

#7.6 VPS / server

• Use the Windows service component; set the service to Automatic in services.msc once it works.
• Open the web frontend via SSH tunnel or locally on the VPS.
• Setup code: C:\ProgramData\trade-commander.com\NewOrderCopier\config\web_setup_code.txt (as administrator).
• Errors of the service: Event Viewer > Windows Logs > Application.
• Use TWS Auto restart and keep TWS/Gateway logged in.
• Linux VPS: .deb or tarball + service; logs with journalctl -u newordercopier -f.

#7.7 Only one copier

• Windows: only one copier (console or service) per machine. Close the console (exit) or stop the service before starting the other.
• Linux: one per data folder – do not run a console and the service at the same time (double copies).

#7.8 Logs for support

• Set Settings > Log files > Loglevel to important for a support case (shows WIRE>/WIRE< broker traffic); set it back to warning afterwards (files grow fast).
• Paths: log/main.log, log/main.csv, log/source/<name>/, log/target/<name>/.
• main.log is complete only after a clean shutdown (exit in the console, or stop the service). A killed process loses the end.

#7.9 Support extract

• Operators only. Log > Orders: click the order → Write support extract...; or in Log files click a line → Write support extract....
• Question "Remove the account numbers from the extract?": No for a file sent to the vendor's support, Yes for a file you publish.
• One ZIP (log_extract_...zip) is written into the data folder and downloaded by the browser. It contains the order trace, the matching log lines and the environment. Nothing is sent automatically.
• Send it to contact@trade-commander.de together with the licence Order ID (shown on the Licence page).

#7.10 FAQ

Can I copy from one IBKR account to other IBKR accounts? Yes: create a TWS/Gateway source (Client ID 0 to include manual orders) and TWS targets. The source must use another TWS/Gateway login (host:port) than the targets and must not share an account with a target.

Can I copy to an FA group? Yes: target = the advisor login, connector Allocation > Allocate to group, method NetLiq / AvailableEquity / EqualQuantity / PctChange.

Do I need a symbol mapping? For MetaTrader and Signal API sources: yes – every symbol needs a row in the connector's mapping table, otherwise nothing is copied. For TWS sources: no (1:1).

How do I copy half the size? Connector Multiplier 0.5. Or Use balance factor to scale by account size.

Are SL/TP copied? Yes, as IBKR stop/limit orders (with hedging/MT4 as one net bracket per contract). Switch off with Ignore stop loss / take profit.

What if the copier was off while I traded? Changes are delivered by the EA on reconnect; positions opened and closed in the meantime are not copied. Use Maintain Source Positions to close copies the source no longer holds. Missing positions are never opened automatically.

Does the copier close my manual positions? Only the Emergency Stop, Close all / Close selected on the Positions page and account protection do. Maintain Source Positions and Flatten when source is flat only close what the copier copied for that source.

Can I test without a licence? Yes, with IBKR paper accounts (DU/DF) as targets.

Can I run it on Linux with MetaTrader? MetaTrader runs on Windows; its EA can connect to a Linux copier over the Remote API port (TLS) with CopierFingerprint.

Can I change the language? Language menu in the web frontend (per browser, immediately).

Is there an auto-update? No. A notice "Version X is available." appears; install the new setup yourself.

#8. Limits and known issues

• Platforms: no macOS. No MetaTrader components on Linux. Windows Server 2016/2019 not supported. No desktop program (browser only).
• MetaTrader as a target is frozen and not offered to new customers.
• Not yet verified against a live account by the vendor: MT5 netting accounts (including reversals), account protection firing, the closing branch of Flatten when source is flat, Maintain Source Positions, Signal API on a live account and from a remote machine, anything on Linux, DarkIce algo on futures. Test these on a paper account first.
• TWS source copies only MKT, LMT, STP, STP LMT (plus bracket children and iceberg/algo attributes). Other order types are not copied. TWS sends no indicator that a manual order is a close, so such an order is copied as an ordinary order. While an order is Inactive, Filled or PendingCancel nothing is sent.
• TWS paper: a cancelled source LMT order is confirmed only about 60 s after placement (error 202), so the copy's cancel can follow late.
• Fractional stock positions (e.g. FA NetLiq allocation): IBKR refuses fractional orders over the API (10243). The copier closes the whole shares; the fraction must be closed in TWS by hand.
• MT4: a pending-order change made while the copier is not running is not resent after the copier starts.
• A position closed in MetaTrader without the copier being told stays in the copier's position book until a restart (unless the EA's report removes it); use Maintain Source Positions.
• No automatic reconciliation: nothing is aligned when an EA connects; Maintain Source Positions only closes, never opens.
• Held MetaTrader market entries are dropped after 45 s while no target can trade (with their close).
• Signal API: commands for a target that cannot trade are dropped, not buffered. The only reply is the ack.
• Licence lock: a position that missed a target stays left out there for its whole life.
• Stored but not applied: mapping Invert; target List mode / Symbols; API channels. Balance factor (live) always shows "unknown". The Executions column Total is not meaningful.
• Reports: equity drawdowns, MFE and MAE are shown as "-" (no market data). The time from the source event to the copier ("arrival") cannot be measured.
• Large FA structures: IBKR rejects the FA group "All" for more than 50 accounts – use a named group.
• Account protection compares the target's total net liquidation; a reading below half the reference is treated as a data error.
• Licence: the copier always holds at least one target account while running; check is online with an offline tolerance only.
• Linux: the single-instance lock is per data folder (console + service could run together).
• Sounds are not played by the web frontend; alerts appear as a red Attention banner.
