Multi-Asset Martingale Trading with Loss-Based Position Increases

Summary

MultiMartin is a multi-symbol expert adviser built around a reversal strategy that increases trade size after each loss. The sequence continues until a profitable trade occurs or a configured multiplication limit is reached, after which the next trade returns to its initial lot size. The settings cover initial size, the growth factor and limit, stop-loss and take-profit distances, starting trade direction, trading hours, and symbol-specific configurations. Stop handling can be fixed, moved to break-even after a specified profit, or trailed from the start.

The document describes adapting an earlier MetaTrader 4 adviser to MetaTrader 5, restructuring it for object-oriented and multi-symbol operation, and fixing bugs. It warns that martingale sizing is dangerous and identifies omitted areas for improvement, including timer-based operation and volatility analysis. It includes references to example reports for single- and multi-currency periods, but provides no figures or discussion of their results. The approach can accumulate large exposure during consecutive losses, and the document gives no evidence that its settings control that risk or establish profitability.

Key ideas

• The adviser raises trade size after losses until a win or a configured increase limit.
• After a winning trade or reaching the limit, sizing restarts at the initial lot.
• Settings control trading windows, symbols, stop and target distances, and stop management.
• The document warns about martingale risk and notes that volatility analysis is omitted.
• Example report periods are named, but performance results are not described.
