Win probability is an assumption
A 52% estimate does not mean every 100 bets will land close to 52 wins. The simulator only reads the risk implied by the assumption you enter.

What it is for
A losing streak does not prove you were wrong. It tests whether your bankroll can take the swing.
Even positive-EV betting can go cold over a short sample. Use this simulator to see how often streaks can show up, then decide whether the stake size is sensible.

Quick answer
Is a five-loss streak always a bad sign?
- No. A 52% to 55% estimated win rate can still produce five straight losses over a normal betting run.
- The real danger is staking too much and damaging the bankroll before the long-term edge has time to show.
Losing streak simulator
Enter bankroll, stake size, win rate and bet count
Check the chance of a losing run first, then check whether the stake size would put too much pressure on your bankroll. A losing streak does not automatically mean the angle is wrong; oversized staking is the real problem.
Common scenarios
Start from an example, then edit the bankroll, stake and win probability to match your own plan.

Main readout
The streak is normal, but watch the stake
A losing run is possible, but it does not prove the bet selection is bad. Ask one practical question: after five straight losses, would you still follow the same plan?

Next step
If five losses would cut too deep, reduce stake size first. If the win probability may be wrong, check the price again with the EV calculator.
Important note
This tool estimates risk. It does not predict match results, casino outcomes or future profit. Real-money betting still depends on win-rate error, market movement, limits and discipline.

Method
How the simulator estimates losing-streak risk
The tool uses your estimated win probability and planned number of fixed-stake bets to estimate the chance of at least one 3-, 5- or 10-loss run. It then maps those streaks against your stake size to show bankroll drawdown. This is variance analysis, not outcome prediction.
More bets make streaks more likely
A 20-bet run and a 100-bet run do not carry the same streak risk. The longer the sample, the more normal it becomes to see an ugly patch.
Stake size decides the damage
Five losses at 2% per bet is a 10% drawdown. Five losses at 10% per bet cuts the bankroll in half. The same streak can feel completely different depending on stake size.
Pre-bet check
Use four inputs to test whether the stake can survive variance
Keep it practical: enter the bankroll you actually use, the fixed stake you plan to bet and a conservative win probability.

Reading variance
How to use the result without overreacting
The result is not telling you whether the next bet wins. It helps you decide whether to continue, cut stake size or pause and re-check the edge.
Normal streak: do not chase
Good betting positions can still lose in a bad order. Look at whether the original plan can survive the run before adding risk.
Oversized stake: reduce first
If a common losing run creates a drawdown you cannot tolerate, the problem is usually stake size, not the existence of a streak.
Question the edge: check EV
If the win probability feels shaky, go back to the EV calculator and check whether the price still has value before continuing.
FAQ
Losing streak risk simulator questions
Answers on losing streak probability, win-rate estimates, positive EV variance, drawdown and chasing losses.
What is a losing streak risk simulator?
A losing streak risk simulator estimates how often a run of consecutive losing bets can appear over a fixed number of bets, then shows how much that run may draw down your bankroll.
Can a 55% bettor still lose five in a row?
Yes. A 55% win probability is a long-term estimate, not a short-term guarantee. In a normal betting sample, five straight losses can still happen.
What is the chance of losing five bets in a row?
It depends on your win probability and how many bets you plan to place. Use the five-loss readout to see whether that run is rare, normal variance or too painful for your bankroll.
Why can positive-EV betting still lose for a while?
Positive EV is a long-term idea. It does not remove variance, so a valuable price can still lose several times before the edge shows up.
Can a positive-EV bettor still blow up a bankroll?
Yes. A positive edge does not protect you from oversized stakes, bad win-rate estimates or chasing losses. If the stake is too large, normal variance can still damage the bankroll before the edge plays out.
What happens if my stake size is too large?
The same losing streak causes deeper drawdown. At 10% of bankroll per bet, five straight losses can remove half the bankroll.
How many losses in a row should make me reduce stake size?
There is no universal number. A practical check is the five-loss drawdown: if that would make you abandon the plan or chase losses, the stake is probably too large.
How do I estimate losing streak risk from win probability?
Enter a conservative win probability and the number of planned bets. The tool estimates the chance of at least one 3-, 5- or 10-loss run under that assumption.
How is this different from the Bankroll Risk Calculator?
This simulator focuses on how often losing streaks may appear. The Bankroll Risk Calculator focuses on whether your stake size, EV and drawdown limits are safe enough.
Should I increase stake size after a losing streak?
No. Increasing stake size after losses can speed up drawdown. Reduce risk first, then re-check win probability and expected value.
Are the simulation results guaranteed?
No. The results are risk estimates based on your inputs. They do not predict actual game, match or market outcomes.
The streak risk is clear. Where should the session stop?
Variance is easier to handle when the exit is written down first. Use the Profit and Stop-Loss Planner next to set a stop-loss, profit target and session limit.
