MT5 source code review, strategy improvement, optimizations and setfiles for XAUUSD

1. Job Description

I already have the full source code of my Expert Advisor mt5
I need a developer to:

    Check the code for errors, bugs, or inefficiencies

    Ensure the EA is stable and compatible with any broker, including:

        4-digit / 5-digit brokers

        ECN/RAW accounts

        Different symbols

        Different timezones

    Optimize the EA for XAUUSD

    Provide high-quality .set files for profitability on my chosen timeframe.

This is NOT a new EA creation job — it is code review + optimization using the existing EA.

    Forward test results (optional but preferred)

    A short summary of:

        What was optimized

        Any errors or issues found and fixed

3. Conditions

    EA must compile with zero errors and zero warnings
