MQL5 trade server return code

MQL5 Error 10019: Insufficient funds for the request

MQL5 error 10019 is TRADE_RETCODE_NO_MONEY, the official trade server return code for insufficient funds for the request. Reduce the requested exposure or resolve the account margin constraint. Use OrderCalcMargin and OrderCheck with the actual symbol, side, volume, and price before sending; never bypass the rejection by weakening risk controls. Read MqlTradeResult.retcode after OrderSend because a successful function return does not by itself mean that the order was executed.

What error 10019 actually reports

The code belongs to MqlTradeResult.retcode, not to the compiler error list and not necessarily to GetLastError. The trade server uses 10019 to report insufficient funds for the request.

Keep the request, the boolean returned by OrderSend, result.retcode, result.comment, and the symbol properties in the same log record. That separates a client-side request failure from a server-side rejection.

Inspect the request before changing the strategy

Use the smallest failing order and compare every broker-sensitive value with the current symbol and account. Do not hide the error by retrying unchanged input.

  • Compare ACCOUNT_FREEMARGIN with the checked margin requirement.
  • Include existing positions, pending orders, and the account margin mode.
  • Recalculate risk-based volume after stop distance, price, leverage, or account equity changes.
  • Inspect MqlTradeCheckResult.margin, margin_free, and comment.

Repair and verify

Reduce the requested exposure or resolve the account margin constraint. Use OrderCalcMargin and OrderCheck with the actual symbol, side, volume, and price before sending; never bypass the rejection by weakening risk controls.

Run OrderCheck with the completed request, log its retcode and comment, then send only if the check is acceptable. OrderCheck improves diagnostics but does not guarantee execution.

Use a focused diagnostic

OrderCheck exposes the projected margin state for the completed request. Its success is diagnostic, not an execution guarantee, and the server remains authoritative.

A valid request can still be rejected or filled differently by the trade server. Check the returned retcode, test with the broker symbol and account, and review risk before any live order.

Check retcode 10019.mq5
MqlTradeRequest request={};
MqlTradeCheckResult check={};

// Fill request.action, symbol, type, volume and price first.
if(!OrderCheck(request,check))
   PrintFormat("OrderCheck call failed, error=%d",GetLastError());
else
   PrintFormat("retcode=%u margin=%.2f free=%.2f comment=%s",
               check.retcode,check.margin,check.margin_free,check.comment);

A practical verification workflow

  1. 1

    Capture the complete result

    Log the OrderSend return value, result.retcode, result.comment, symbol, order type, volume, price, stops, and filling mode. Confirm that the retcode is 10019.

  2. 2

    Read current constraints

    Query the symbol and account immediately before building the request. Broker constraints can differ between symbols and sessions.

  3. 3

    Change the invalid field

    Reduce the requested exposure or resolve the account margin constraint. Use OrderCalcMargin and OrderCheck with the actual symbol, side, volume, and price before sending; never bypass the rejection by weakening risk controls.

  4. 4

    Check, send, and retest

    Call OrderCheck, submit the corrected request, then reproduce it in Strategy Tester and a demo account before considering live use.

Frequently asked questions

What does MQL5 error 10019 mean?

It is TRADE_RETCODE_NO_MONEY, the official MQL5 trade server return code for insufficient funds for the request.

Is 10019 a GetLastError code?

Treat it as a trade server return code when it appears in MqlTradeResult.retcode. GetLastError reports the terminal runtime error layer, which is a separate diagnostic channel.

Does OrderSend returning true mean the trade executed?

No. The official OrderSend reference says true means the request passed basic checks and was accepted for processing. Inspect result.retcode and subsequent trade events to determine the outcome.
