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

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
