Calculate how much to stake on the opposing outcome to lock in guaranteed profit or limit your losses.
Hedging makes most sense when your original selection has won enough to shorten significantly in odds, and you want to guarantee a profit rather than risk a zero return. The trade-off is accepting a smaller guaranteed profit vs a larger uncertain one.
Bookmaker "cash out" is essentially hedging — but the bookmaker calculates the hedge at odds that include their margin, giving you less than the true mathematical value. Manual hedging via an exchange or opposing bookmaker typically yields 3–8% more.
You don't have to hedge fully. A partial hedge reduces risk while maintaining upside. Decide how much of your potential profit you want to guarantee vs how much you're willing to risk for the maximum payout.
