Trend Trading with Moving Averages, Parabolic SAR, and Martingale Risk

Summary

This Expert Advisor identifies trend conditions with three moving averages and uses Parabolic SAR to trigger orders. It can close a position on an opposite signal, trade only on selected days, reverse its signal, or keep a position open when an opposite signal occurs. Stop loss can be fixed or set from the distance to the Parabolic SAR point, with a multiplier; take profit can likewise be fixed or derived as a multiple of the stop distance.

Position size is tied to a chosen percentage of account balance and the stop distance. An optional martingale setting increases the risk after a losing trade by a multiplier, while the non-martingale mode recalculates size from current balance. The EA also describes moving a stop loss into profit after a specified gain. These are parameterized mechanics, not evidence of profitability: the document provides no backtest results, market or timeframe context, or analysis of drawdowns. The loss-driven risk increase can amplify exposure after losses, so the described controls do not establish that the approach is safe or robust.

Key ideas

• The EA combines three moving averages for trend context with Parabolic SAR for trade signals.
• Stop loss and take profit may be fixed or calculated using SAR distance and configurable multipliers.
• Position size depends on account risk and stop distance.
• The optional martingale mode increases risk after a losing trade.
• A profit threshold can trigger a stop adjustment, but the document supplies no performance or drawdown evidence.
