Back two or more outcomes from one stake so that whichever one wins, you collect the same amount. Enter your total stake and each price — the tool splits it for you.
Only if the combined implied probability of the outcomes you cover is below 100%. That happens when two different books price an outcome differently, which is rare but real.
An accumulator needs every leg to win. Dutching means only one of your selections needs to win — you are spreading risk across outcomes in the same market, not stacking risk.
