https://en-betfair.custhelp.com/app/ans ... l/a_id/406There is a difference on how the reduction factors work on 'Place' markets compared to 'Win' markets.
Win markets reduction factors are calculated to 100% when adding up all runners. In a 'Place' market a single horse has less impact on your chance of winning and reduction factor totals can be well over 200%.
The main difference between the two markets is that in a 'Place' market the reduction factor is applied to the potential winnings on the bet only and not to the traded price.
- You matched a back bet in a place market on the horse 'Diamond Night' for £10 @ 8.0.
- Your potential winning would be £10 x (8.0 - 1) = £70
- A horse in the same race is now withdrawn with a reduction factor of 25%
Your potential winning would be now £70 x (100% - 25%) = £70 x 75 / 100 = £52.50
Therefore the reversed traded price would be 6.25.
(In a win market a 25% Reduction Factor would calculated a price of 6.0).
Other differences of 'Place' markets:
All reduction factors will be applied (2.5% or less included)
Only if the reduction factor for a withdrawn horse is 4.0% or greater, all unmatched lay bets will be cancelled.
A place to discuss anything.
Note that reduction factors are slightly different in place markets, its applied to the winnings rather than the price and there is no 2.5% minimum.
Again useful information thanks.firlandsfarm wrote: ↑Fri Oct 23, 2020 11:09 amHave a look at Leicester 30/06/2020 17:45 TO BE PLACED. (Remember that's in the dwbfpricesukplace01072020.csv Betfair SP file). From my database there was originally 9 declarations but only 5 eventual runners ... the file shows 3 places were paid! There is no question of before or after a withdrawal.
