Adaptive DDQN MT5: Free MT5 Expert Advisor

Overview

Adaptive DDQN MT5 utilizes a Deep Q-Network to make trading decisions based on market states derived from technical indicators, volatility, and supply-demand zones. The system manages trades using a grid-based basket approach with lot scaling via a multiplier. Risk controls include take profit, optional trailing stops, and equity-based guards, though it defaults to no fixed stop loss per trade. It features experience replay and persistent memory to adapt to market conditions across multiple symbols.
