The mission is:
Let's say I have a series of spreadsheets. They comprise win strike rates, based on 1st favourites tote price and no. of runners. They indicate the order of % win strike rate for each horse in the race.
The formula might be: Lay the 6th, 7th & 8th favourites in an 8 horse race IF the 1st favourites tote price is $2.50 and 6th favourites tote price is > $20.
The formula is easy enough to program in most bots but the conundrum for me is triggering a bot to fire a series of Lay bets to Betfair, but based on TAB prices?

Any suggestions?.........thanks RP
