Rule 4

During this video, you will learn how to use the rule 4 calculator, to work out what the new price will be, following a horse withdrawal from a race.

The questions we will answer throughout this video, will be; What is ‘rule 4’ in horse racing?, Why is it necessary?, When should I use the calculator?

As a general rule, if your bet has already been matched, you should leave it to run, as rule four should just about even out on both sides.

You should use this calculator, if you’re in a position where you have unmatched bets and you need to workout your new back and lay bet prices.

We’ll then take you through examples of us using it, so you can follow us along and learn yourself.
