Crash 300 Jump Diffusion EA: Free MT5 Expert Advisor

Overview

Crash 300 Jump Diffusion EA employs a jump-diffusion model to detect price spikes and enters long positions during the subsequent recovery drift phase. The robot manages trades using fixed stop loss and take profit targets, with additional logic to exit positions early if a new spike is detected. Risk management includes fractional Kelly sizing and a bounded martingale recovery system with a 1.5x multiplier. It also incorporates UTC time filters, an equity floor protection, and a spread filter to ensure entries occur during optimal market conditions.

Post-spike bull candle entry logic

Fractional Kelly and fixed risk position sizing

Bounded martingale recovery with configurable multiplier

Spike-exit mode to close trades during sudden drops
