What happens if I choose the “Keep” option on an unmatched lay bet and there is a subsequent non-runner?
When a non-runner is removed from a horseracing market it is Betfair’s policy to cancel unmatched offers to lay all other horses in the market if the non-runner has a reduction factor of 2.5% or greater for win markets, or 4.0% or greater for place markets. In these circumstances offers to lay a horse with the ‘At In-Play: Keep’ option selected will not be cancelled. Instead the lay odds offered or requested in place markets will be reduced in proportion with the reduction factors of any non-runner(s) and the same will apply in win markets providing the relevant non-runner has a reduction factor of at least 2.5%.
