Read the result correctly
Implied probability is the break-even rate derived from a price before adjusting for bookmaker margin. An accumulator return assumes every selection wins and does not account for void rules, tax, stake limits or settlement differences.
A positive user-entered expected value depends entirely on the probability estimate being accurate. These tools cannot predict outcomes or make betting profitable. Set an affordable limit and use self-exclusion if gambling becomes difficult to control.
