Your win rate, your volume — the exact probability of every skid length, and the longest one you should expect. Know it now, on paper, so it can't panic you live.

What this tool does — and why it matters ▾
Every bettor who quits a winning strategy quits during a streak the math had already guaranteed. The Cold Streak computes — exactly, not by simulation — how likely every skid length is at your numbers, so variance arrives as a scheduled visitor instead of an ambush.
Exact probabilities. The run-recurrence gives the true chance of at least one L-loss streak in N bets — precise to the decimal, for every L from 3 to 15.
The expected longest skid. The median worst streak for your window — the one you should plan your unit size around, because it's coming either way.
The coin-flip line. The streak length that's a 50/50 to happen — a one-number reality check for any hot-take about a "collapse."
The warm side too. Your longest expected WIN streak — same math, pointed the other way, so the heater doesn't fool you either.
Bankroll consequences, named. The verdict connects the near-certain streak to stake sizing — if the scheduled skid would cripple the roll, the unit is too big today.
Every league, offline, forever. Pure math on your phone. Pairs with The Long Run, which shows the same truth as 2,000 drawn futures.
