Independent MQL5 Code Audit for an Existing MT5 EA

Specification

I am looking for an MQL5 developer to independently review an existing EA’s execution and position management logic.

The review should focus on duplicate orders, trade isolation by symbol and magic number, broker price and volume constraints, error handling, and recovery after a terminal restart.

This order is for an audit report. Please do not modify the source or change the trading strategy.

For each finding, provide the relevant function or code location, severity, explanation, and a reproducible scenario where possible. Separate confirmed defects from potential risks and optional improvements.

I will share the source privately for scope review before agreement. Please include your review approach, one relevant example of your work, and your estimated turnaround. Any implementation fixes will be agreed separately.

I want to create an EA that will take trades according to a trading zone condition. The logic will start with the identification of a trading zone for BUY and SELL in the EA. After the trading zone has been identified, then the EA will use the current time frame prices to determine if the market will be a BUY or SELL. The market will be a BUY if the low price range goes above the lowest price after the installation
