IF you were betting via WA Tab (as that is the only one I can currently access automatically) and IF you are happy to load up your selections and parameters and leave your PC running and connected to the inernet all day, I think I can provide you with the program you need.

Staking plans usually require the previous result affecting the next bet. You could keep the staking plan for better value if that is what you want, though automatic bet increases are fraught with danger.

No, I am not looking for an up-front payment. Though should this be successful, I would expect some sort of commission ;-)

Seriously though, if I provide you with say a simple grid (Date, Venue, Race, Selection, Bet, Lower Limit, Upper Limit) would that do it?

We could call ourselves "The Usual Suspects".
