How this is calculated
This uses month-over-month compounding. Each losing month reduces the account by the stated percentage of its balance at that point, not a percentage of the original starting balance.
A shorter losing streak erases the same gain faster than most traders expect, because compounding losses shrink an already-reduced balance.
This is a mathematical projection based on the numbers you enter, not a forecast of how many losing months you will actually have.
Actual losing streaks are rarely a fixed percentage every month. Use this to understand the shape of the risk, not as a precise prediction.
