Modify a (Pruning) Grid EA

Overview

I am looking for an experienced MQL5 developer to build a custom MetaTrader 5 Expert Advisor based on a grid-cycle trading framework.

This is not a standard grid EA. The system combines:

• Session-based trade initiation
• Multi-filter signal generation
• Dynamic grid management
• Advanced basket management
• State-machine-driven trade lifecycle management
• Dynamic take-profit handling
• Risk management and exposure controls
• Modular architecture for future expansion

Some part of the EA already exists but it wasn't completed by one of the dubious developers here, hence I need someone to complete the work.

The complete strategy specification will be provided only to shortlisted candidates after an NDA or initial qualification discussion.

Core Requirements

The EA should be developed using a clean, modular architecture and support:

Entry Engine

• Multiple configurable entry filters
• Indicator-based signal generation
• Candle-close confirmation logic
• Time/session restrictions

Grid Engine

• Dynamic grid expansion
• Multiple grid spacing methodologies
• Configurable lot sizing models
• Support for advanced trade grouping logic

Basket Management

• Dynamic basket profit calculations
• Cost-aware profit management (spread, commission, swap)
• Trade restructuring capabilities
• Advanced position lifecycle management

Risk Management

• Exposure controls
• Drawdown protection
• Maximum position limits
• Margin usage controls

State-Based Execution

The EA will require implementation using a structured state-management approach rather than a simple trade-by-trade execution model.

Technical Requirements

The developer should be comfortable with:

• Advanced MQL5 programming
• Object-oriented design in MQL5
• State machine architecture
• Complex order management systems
• Multi-position basket calculations
• MT5 Strategy Tester optimization
• Efficient CPU/memory usage

Deliverables

• Source code (.mq5)
• Compiled EA (.ex5)
• Full input parameter documentation
• Bug-fix period after delivery
• Support during testing phase

Preferred Experience

Please provide examples of:

• Grid EAs
• Basket trading systems
• Recovery systems
• Trade management frameworks
• Complex MT5 projects
