Advanced MQ4 Expert Advisor Templates: Free MT4 Expert Advisor

Overview

Advanced MQ4 Expert Advisor Templates handles complex trade management tasks, including multi-symbol execution, margin-based position capping, and various lot-sizing algorithms such as risk percentage or fixed volume. Risk controls include ECN-compatible hidden stops, ATR-based trailing stops, and multi-level breakeven settings. While it supports optional martingale lot scaling and directional logic toggles, the core entry and exit conditions must be defined by the developer. It includes built-in logging, account statistics, and time-based trading restrictions.

Multi-symbol trading support and spread filtering

Integrated risk management with hidden stop loss and take profit

Custom trailing stops using moving averages or ATR values

Position capping by quantity or usable margin levels
