Martin Boy: Automated MT5 Trading with Verified Long-Term Stability and Performance

In this detailed Martin Boy review for 2025 I present a balanced performance and risk analysis based on available backtests and live sample accounts. The review covers how the expert advisor implements a pure mathematical martingale grid model and why the developer emphasizes entering historical maximum and minimum price bounds; without those bounds the strategy may suffer prolonged one-sided exposure. Martin Boy is unique because it explicitly documents parameter baselines for the GBPJPY pair and requires pair-specific backtesting before deployment to other markets. The algorithm opens grids in both directions and applies calculated martingale multipliers to recover from adverse moves while attempting to preserve long-term profitability. The code focuses on mathematical consistency rather than discretionary signals, using predetermined steps, multipliers, and order limits to shape risk. Martin Boy handles ranging markets and choppy volatility more predictably than strong trending environments, where sustained directional moves can trigger extended drawdowns. The developer, Jie Lin Wang, provides recommended parameter sets and highlights a 25-year backtest window as evidence of stability. Practical use demands strict position sizing, an account size that can withstand several amplified grid resets, and ongoing monitoring. Overall, Martin Boy offers a transparent, parameter-driven approach to grid martingale trading on MT5, appropriate for traders prepared to manage higher risk in exchange for potential steady returns over long horizons.
