When to Hedge a Live Bet
You have a live bet with one leg remaining. The opposing side is now offered at price you can hedge against. Hedge math is simple — the harder question is whether to hedge at all. The answer is always an EV question.
The hedge math
To lock in the same payout on either outcome, set hedge stake = (original stake × original decimal odds) ÷ hedge decimal odds. Then subtract original and hedge stakes from the locked payout to get guaranteed profit. The calculator on this site automates the arithmetic.
When hedging is +EV
If the live hedge price has more vig than the open ticket originally had, the hedge is mildly −EV in long-run expectation. If the live price is sharp (low vig), hedging is roughly neutral and the trade is variance for certainty. If the live price overpays the true probability, the hedge itself is a +EV bet.
When letting it ride is +EV
If your model still thinks the remaining leg is more likely than the live implied probability says, you should not hedge. The expected value of letting the ticket ride is higher than the locked profit. Variance is real, but on the math the bet is still +EV.
The bankroll question
Beyond the math, hedging is also a portfolio question. If a single ticket is large relative to bankroll, reducing variance has real utility even if it is mildly −EV. Sharps with deep bankrolls almost never hedge for variance reasons. Smaller bettors sometimes should.
Common mistakes
- Hedging by default any time a parlay reaches the last leg.
- Hedging without checking the live price's vig.
- Forgetting to size the hedge to lock the same payout on both sides.
