Back testing on Betfair
 

I am just looking at running some back tests on a selection method using betfair prices. What price should I use, is the WAP the one to target? Obviuosly its never going to be accurate (WAP price), but it should be a case of swings and roundabouts? Sometime it will be higher than the price you woudl have taken, and sometime lower? Would that be a fair assumption?

If not, what would you take?

I use the last available back or lay price.

Yes, the last back or lay price would be better as the WAP is biased.

I'll throw a party with free drinks, when they finally implement SP for us, but it could be a pensioner's party the way things are looking.

However, I was easily able to beat Top Fluctuation on all the shorties today, so fairy bread all round ;)

Okay thanks guys, will use that as my price then.

Hey, Chrome, us pensioners don't need B/F SP to have a party!
