Oxa / Welldone,
Thanks - brilliant work - so much more to work with now - how can we not make a profit ? And you've been very responsive to all our requests.
Can I ask, in the manual I see there are two bits of 'Silk' info:
silk_numerator integer The forecast price numerator.
silk_denominator integer The forecast price denominator.
I cannot get on BF just now to look, but where do these forecasts come from - I did not see them last time I looked there.
Hi Alfaman,
If I understand right: (silk_numerator/silk_denominator)+1 = Betfair Forecast Price (decimal).
I think it makes sense to change these variables to "silk_forecast", then we don't have to do the extra calculation in our formula. It does not make sense to use "silk_numerator" or "silk_denominator" as a stand alone.
I believe the ratings are computed by Timeform and the sum of all forecast prices will be 100%, i.e. no overround included.
These forecast prices are also the base for the Betfair reduction factor calculation. Note: Forecast prices (and therefore also reduction factors) might be adjusted during the trading session prior to the off.
You can find the Betfair forecast prices at the Betfair site. Select a horse race, then click "Race Card" and after that click "Form/Results".
Cheers,
