Specification
I have an existing MT5 Expert Advisor that has already been developed and debugged. I am looking for an experienced MQL5 EA developer with strong strategy-analysis, backtesting and optimization experience to review and improve the existing system.
This is not simply a coding job.
I am specifically looking for someone who can analyze an existing EA and independently identify weaknesses in its trading logic, rather than simply implementing a list of indicators or features that I provide.
Initial objective
I want the developer to first:
Review the existing MQL5 source code and trading architecture.
Analyze the current entry and exit logic.
Identify potential weaknesses and poor-market conditions.
Review the existing trade-management and risk-management structure.
Assess why the EA may miss good opportunities or take lower-quality trades.
Recommend possible improvements before major coding begins.
Assess whether the strategy can be effectively expanded to multiple markets.
Recommend a suitable multi-symbol approach.
Potential markets may include XAUUSD, NASDAQ, US30, GBPJPY, EURUSD, GBPUSD, EURAUD and other suitable instruments, but I do not want to force a particular list. I want the developer to determine which markets are actually suitable for the strategy.
The objective is for the EA to have more opportunities by scanning multiple markets, without forcing trades simply because another symbol is available.
Risk management is a priority
The EA already has an established risk-management framework.
I do not want profitability improved by:
Martingale
Grid/recovery systems
Increasing risk after losses
Removing daily loss protection
Excessive leverage
Curve-fitting
I want the developer to improve trade quality, market selection, entries, exits and overall risk-adjusted performance while preserving strong capital protection.
Testing
I want proper testing rather than optimization based on one historical period.
Where appropriate, testing should include:
Multiple historical periods
Different market conditions
In-sample/out-of-sample testing
Strategy Tester optimization
Drawdown and losing-streak analysis
Profit factor and expectancy
Forward/demo testing where practical
Comparison between the current EA and the improved version
Measures to reduce overfitting/curve fitting
Important
Please do not start coding immediately.
I want the first stage to be an assessment of the existing EA and a proposed improvement plan.
After reviewing the proposal, we can agree on what should actually be changed and proceed with development/testing.
Please answer these questions when applying:
How many years of MQL5/MT5 EA development experience do you have?
Have you worked on strategy optimization and backtesting, not just coding?
Have you worked with multi-symbol/multi-market EAs?
How do you prevent curve-fitting when optimizing an EA?
How would you diagnose whether poor EA performance comes from entry logic, exit logic, market conditions, or risk management?
Have you worked with out-of-sample or forward testing?
Please provide examples of similar EA strategy-analysis/optimization work if available.
What would you expect to accomplish within the initial 14–21 day period?
I am looking for a developer who can give an honest professional assessment, even if that means recommending significant changes to the existing strategy.
I am not looking for someone to promise a specific percentage return.
The goal is to determine whether the existing EA can be made more robust, more selective and more consistently profitable while maintaining strong risk management.
