Best price execution is an exchange feature that ensures a bet is always matched at the best odds available at the time.

When best price execution occurs, it is bet quantity which stays constant after a user benefits from a better price.

Bet quantity is defined as: stake * odds. So the new stake (after BPE) = the bet quantity/improved odds.

This will either reduce your potential losses, increase your potential winnings or a combination of both. It will never increase your potential losses. Your bet will never become matched at less favourable odds than you requested.

Lay example

A £1 lay bet is placed on odds of 5.0, but matched at 4.0. The original bet quantity is £5 (1*5). Therefore the new stake will be £5 / 4.0 = £1.25. The liability will be £1.25 * (4.0-1) = £3.75.

Note: If placing a lay bet, the backer’s stake might increase. This stake refers to your potential winnings. Your liability (potential losses) will never increase.

Back example

A £5.00 back bet is placed on odds of 3.0, but matched at 4.0. The original bet quantity is £15.00 (5*3). Therefore the new stake will be £15/4, which is £3.75, while the potential winnings improves from £10 to £11.25.
