Monte Carlo Trade Simulator

Simulate 500 random trade sequences using your actual win rate and risk-reward ratio. See the range of outcomes your strategy can produce — from best case to ruin.

What is a Monte Carlo Simulation?

A Monte Carlo simulation runs your trading strategy through hundreds of random trade sequences to show the full distribution of possible outcomes. Even a profitable strategy can produce losing streaks — this tool helps you quantify that risk.

Why it matters

Back-testing shows one path. Monte Carlo shows all possible paths. A strategy with a 60% win rate and 1:2 RR is profitable on paper, but you need to understand the drawdowns you might face along the way.

How to use the results

  • Risk of Ruin: If this exceeds 5%, consider reducing risk per trade.
  • Worst case: Use this to set your psychological floor — can you handle this drawdown?
  • Median: This is the most likely outcome of your strategy over the sample size.
