Betfair takes commission from your winnings, so the price on the screen isn't what you really get. Work out the lowest price worth taking, or check whether the price in front of you has an edge.
Enter your chance and the edge you want.
Uses the chance and commission from the left. Type the Betfair price you can get.
Rule of thumb: if the edge is under your target, skip the bet or leave an unmatched bet at your price and let the market come to you.
Fair odds are 100 ÷ chance. A 45% chance is fair at 2.22.
Add your edge: 2.22 × 1.05 = 2.33. That's what you need to receive.
Betfair only takes commission from the profit, so the price you ask for is 1 + (2.33 − 1) ÷ (1 − 0.08) = 2.45.
That's the hard part. A gut feel won't cut it. PunterPrice works it out from the sharpest markets and Betfair's own form ratings, for every horse and every Over 2.5 goals game, then gives you this price automatically.
