Specification
I am looking for an experienced MQL5 / MetaTrader 5 (MT5) developer to make targeted improvements to an existing, fast-execution Expert Advisor (EA).
The EA is already functional and actively trades Gold (XAUUSD). The main objective is not to build a new EA from scratch, but to review the existing code and make a few precise improvements, particularly around risk management and risk-to-reward (RR) logic.
Current EA
- Platform: MetaTrader 5 (MT5)
- Language: MQL5
- Instrument: Gold / XAUUSD
- Existing EA with fast trade execution
- EA is already operational
- Strategy logic is largely complete
Main Problem
The main issue I need help with is the risk ratio / risk-to-reward management.
I need the developer to:
- Review the existing risk-management calculations.
- Check how lot size is calculated based on account risk.
- Verify that Stop Loss (SL) and Take Profit (TP) are being calculated correctly.
- Ensure the intended risk-to-reward ratio is correctly applied.
- Check that the EA handles Gold's point size, tick size, tick value, contract specifications, and broker digits correctly.
- Identify any calculation that could cause the actual risk to differ from the intended risk.
- Make the necessary corrections without negatively affecting the EA's existing execution speed or trading logic.
Additional Requirements
The developer should be able to:
- Understand and work with an existing MQL5 codebase.
- Make minimal, targeted modifications rather than unnecessarily rewriting the EA.
- Preserve the existing entry and execution logic unless a change is specifically required.
- Ensure compatibility with different MT5 broker specifications where possible.
- Properly calculate position size according to the desired percentage/fixed monetary risk.
- Correctly handle SL/TP distances and risk-to-reward calculations.
- Test the modified EA using the MT5 Strategy Tester.
- Provide a clear explanation of what was changed and why.
