MT5 EA Refactor: Refine Execution Logic & Expand Exit Engine (Full Spec Provided)

Looking for an experienced MQL5 developer to refactor and upgrade an existing Expert Advisor (EA) trading system.

Current State: I have the fully working Phase 1 .mq5 source code. However, the execution rules are overly rigid, resulting in missed setups.

Scope of Work (Phase 2):

• Refactor entry logic to support multi-timeframe EMA trend alignment (H4 structural trend + M5/M15 execution EMAs).

• Upgrade pullback state machines (touch-sequence tracking, reference EMA locking, and configurable tolerances).

• Implement multi-entry capabilities ( InpMaxEntriesPerTouchSequence & InpMaxOpenTradesPerTouchSequence ).

• Expand execution options: Optional filters (ADX, ATR, Bill Williams Fractals) using strict AND logic.

• Upgrade exit engine: Implement Partial Close (50% at target) + Runner with dynamic $R$-based trailing stop loss and breakeven/profit-locking features.

• Maintain existing safety modules (daily/weekly drawdown protection, spread filters, account risk % sizing, hedging support).

Requirements & Deliverables:

• Complete Final Requirements Specification Document is available —no ambiguity or discretionary design needed.

• Deliverables: Full .mq5 source code, compiled .ex5 , default .set preset, and clean diagnostic logs.

• Code must survive terminal crashes, timeframe changes, and reboots with persistent state variables.
