MT5 EA Journal Error Checklist

Read one failed MT5 EA event across Experts and Journal, identify the broker or terminal constraint, and define the next safe check before changing code.

The checklist

  1. 1

    Fix the exact time window

    Record the local and broker-server time around one failed action. Keep the surrounding Experts and Journal lines together.

  2. 2

    Preserve both original logs

    Use File → Open Data Folder. The EA-side Experts log is under MQL5/Logs; the platform Journal is under Logs. Copy, do not edit, the originals.

  3. 3

    Keep private data private

    Remove account IDs, IP addresses, credentials and order details before sharing excerpts. Never publish a complete raw terminal log.

  4. 4

    Separate signal from execution

    Record whether the EA reached its entry rule, built an order request, received a trade return code, or never attempted an order.

  5. 5

    Check invalid stops

    Compare the requested SL/TP to current bid/ask, tick size, stops level and freeze level. Recheck with OrderCheck before a retry.

  6. 6

    Check money and volume

    For insufficient funds, compare free margin and OrderCalcMargin. For invalid volume, check symbol minimum, maximum and step.

  7. 7

    Check time and permissions

    For market closed or AutoTrading disabled, verify server time, symbol session, terminal Algo Trading and EA permissions.

  8. 8

    Avoid blind retries

    For busy context or off quotes, verify outstanding requests and live prices. A repeated send can create an unintended duplicate.

  9. 9

    Define one acceptance case

    State the original failure, expected behavior and exact no-trade or successful-check result on the same broker environment.

Common questions

Can a phrase count diagnose my EA?

No. The same phrase can have different causes. A count identifies log lines to inspect alongside the request, return code, symbol settings and original source.

Does zero matches mean my EA works?

No. It only means no configured phrase appeared in the copied portion of the logs. Missing logs and silent code paths require separate checks.

Do I need to share account access?

No. One redacted incident, authorized editable source, inputs and relevant environment facts are enough to scope a bounded repair.

Trading risk disclosure

Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading, and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Hypothetical performance disclosure

Hypothetical performance results have many inherent limitations. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown. There are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. Hypothetical results are generally prepared with the benefit of hindsight, do not involve financial risk, and cannot completely account for the impact of financial risk in actual trading. Market conditions, the ability to withstand losses, and adherence to a trading program can all materially affect actual results.
