Distribution of the longest losing streak

Streaks at or above your threshold Shorter worst streaks

One simulated run

Each square is a trade. Blue wins, red losses; the longest losing streak is in solid red.

Runs 10,000 random sequences and counts how often the streak shows up.

How it works. The headline number is exact, not simulated. It tracks the length of the current losing run trade by trade and adds up the probability of every path that reaches your threshold.

Assumes each trade is independent with the same win rate, and that breakeven trades are excluded. Real P&L has regime changes and correlated losers, so live streaks tend to run longer than this model suggests.
