MQL5 Developer Needed: Repair Existing Trading Indicator, Improve Logic, Add Missing Controls

Specification

I’m hiring an experienced MQL5 developer to finish and fix an existing project (NOT building from scratch).

I have:

  • An existing MT5 EA (.mq5 + .ex5) that is based on my TradingView logic

  • A TradingView indicator version used for signals/alerts

  • The EA works but has logic/consistency issues and needs improvements + cleanup

Goal

Make the EA reliable and consistent:

  • Ensure entries/exits match the intended logic

  • Fix missing/incorrect trades vs expected signals

  • Improve execution + risk controls

  • Make it production-ready for live trading with stable behavior


Scope of Work (must-have)

1) Signal/Trade Alignment

  • EA should match the indicator’s conditions consistently

  • Fix cases where signals plot but EA doesn’t enter, or EA enters unexpectedly

  • Confirm bar-close vs intrabar logic is consistent and selectable

2) Execution / Trade Handling

  • Add Close on Reverse (if buy open and sell triggers → close buy then open sell, and vice versa)

  • Add Max Positions / Scaling option:

    • Allow multiple positions, but total risk stays the same (split risk across positions)

  • Add/confirm Session Filter works correctly (time windows)

  • Add/confirm Spread / Slippage / Requote guard (avoid bad fills)

3) Broker Compatibility

  • Add symbol suffix/prefix handling (ex: .VIP, -ECN, etc.)

  • Robust symbol selection and error handling

4) Risk & Safety Controls

  • Confirm risk-based position sizing is correct

  • Add:

    • Daily loss limit (optional but preferred)

    • Max trades per day (optional)

    • One-trade-per-signal protection

5) Code Quality / Stability

  • Clean up warnings, prevent runtime errors

  • Log meaningful messages for debugging (entry reason, blocked reason)


Deliverables

  • Updated .mq5 source code + compiled .ex5

  • Clear notes explaining:

    • What was changed and why

    • How to configure inputs properly

  • Confirmed working via:

    • Strategy tester results + screenshots/logs


What I Will Provide

  • Current EA (.mq5/.ex5)

  • TradingView indicator logic reference

  • A list of known issues + examples (screenshots)

  • My preferred settings for best results


Requirements (to filter good devs)

Please apply only if:

  • You have solid experience building/debugging MT5 EAs

  • You understand backtesting differences (ticks, bar close, spread)

  • You can explain logic clearly and keep signals consistent

In your proposal, include:

  1. Examples of EAs you’ve fixed (brief)

  2. Your plan for debugging alignment issues

  3. Estimated timeline and cost range

I am looking for an experienced MQL4/MQL5 developer to build a custom MT4 indicator from scratch or cracking my ex4 file that i provide to you. I already have an existing indicator (EX4) which produces highly accurate buy/sell signals. I want a similar indicator developed based on its observable behavior and signal structure. my existing indicator is pc id protected so you have to do PC ID security bypass and source
Patricia Ukawilu 6:43 PM I need help creating an EA to optimize my trade. I already have a preliminary pine script which I will want optimized and create an EA from it to optimize my trade on MT4. I also subscribed to a signal app. I’m looking to automate the execution of the signal from the app so as not to miss out on good trades
