Monte Carlo Simulation

Bootstrap-resamples this strategy's own historical, NET-of-costs R-multiples (same trades the Trading Costs page uses) WITH replacement to build 2,000 alternate trade sequences, each as long as the real historical trade count — this captures the actual distribution's shape (fat tails, losing streaks, the real win rate) rather than assuming a clean win-rate/reward:risk model, and is cost-inclusive by construction. Starting balance $1,000, 1% of current balance risked per trade, compounding.

Caveat: bootstrap resampling assumes trades are independent (no serial correlation) — this project's own regime/walk-forward analysis found session and regime effects that mostly don't survive rigor, which supports independence as a reasonable approximation, but it isn't literally true for a trend-following-style structure strategy in real markets with regime persistence. Treat the figures below as a model of the historical trade distribution's dispersion, not a guarantee of future behavior.
