What is a non-runner?
A non-runner is when a horse is removed from the line up of a race just before the start, this can happen for a number of reasons and some people believe that it can adversely affect the results of the race. Generally if you have placed a bet on a horse that becomes a non runner betfair will cancel your bet.



This is the master control for betting on races based on the number of runners, formerly in the bet settings tab

For example :  should wish to only bet on races with more than 8 runners then you would select  9  to 30



The way this feature works is as an additional to the standard number of runners restrictions.

So let’s say for example that I want to bet on races with 0- 30 runners but specifically not on races with 9 runners. You just need to enter 9 in the exclusion box



We have added 1 to 9 but if you choose "1" then the Grey Horse bot will not bet if  there is 1 or more non runners in the race
 


Each horse in a race is given a “Reduction Factor” this worked out by how much
the race will be affected if the runner is removed. Hot favourites normally are 25% or more where an outsider may be as little as 1% or less.




We have found that directly after a suspension (similar to in running) the prices can get a little strange so this option allows you to stop betting during this time. A 20 second setting seems to be good enough.



The fact that the number of non runners can quite strongly affect the outcome of a race is not new however there are some interesting ways that this can be used to your advantage.
This feature allows you to restrict betting unless there are a number of non runners before your start betting TTS time.
