Alternating EURUSD Martingale EA with Loss-Based Lot Increases

Summary

This Expert Advisor uses a fixed alternating direction: it starts with a buy and switches between buys and sells on successive trades. It opens trades at candle starts and applies stop loss and take profit settings. After a losing trade, the next position size is multiplied by a fixed coefficient; after a profitable trade, sizing returns to the initial lot. A maximum lot cap resets sizing to the initial amount when reached.

The document identifies EURUSD on the hourly timeframe and gives an optimization period, but supplies no readable backtest results. It presents the EA as a starting point for adapting a strategy, not as evidence of profitability. The method is a martingale-style progression: increasing exposure after losses can compound drawdowns and does not ensure recovery. The implementation example is intended to work across MetaTrader versions, though the excerpt alone does not establish that its code handles every history, execution, or platform edge case correctly.

Key ideas

• The EA begins with a buy and alternates trade direction thereafter.
• It increases the next lot after a loss and resets to the initial lot after a win.
• A maximum lot setting limits the progression by resetting sizing when exceeded.
• The document gives no backtest statistics to establish profitability or risk.
