Advent of Alpha Day 20: Best Price Execution Fun

When you take a price ticks away from the best price available, you will get matched at that best price by default.

But you can turn it off at an account level in some jurisdictions. Why should you ever not want best price execution?

Sometimes you will be betting and the price will move between you sending the bet and it getting matched, and you will then want to cancel your bet (think in-play and betting on an outcome which becomes less/more likely during the bet delay).

Sometimes though, turning off best price execution (BPE), might open up other opportunities.

Imagine though that you think the price “should” be at a certain level after an event and you fire bets in at that price continuously through a betting delay, thinking that event (last price, a goal, whatever), get rejected because BPE isn’t on, and then get matched for the first time. You’ve effectively beat a queue.

Betfair reportedly don’t like this, but I don’t know by how much they’ll penalise you for it.
