Hi mcbee,
I copied and pasted your formula "default_backa+(market_mbnum*.10)"
However that increases the bets by increments of 10 using a 5.00 bet stake
they appear as follows 5.10, 5.20, 5.30, 5.40 etc.
What I am trying to achieve is to increase the bet by 10% from
the last bet. So if last bet was 5.00 then next bet is 5.00*1.1 =5.50 and next bet would be 5.50*1.1= 6.05.
The idea is to bet only when a change of favourite.
eg: Horse A @ 2.80 Fav bet = 5.00 ...... then B becomes fav at 2.30
So Horse B @ 2.30 Fav bet = 5.50 (5.00*1.1=5.50)........ then A becomes fav again
So Horse A @ 2.10 Fav bet = 6.05 (5.50*1.1=6.05) etc etc
The fav order may only change a couple of times in a race so there would only be a handful of bets at most in one race, but they could involve the same horses swapping fav order.
Hope this is clearer
Many thanks if a solution could be found.
