Hi mattio, The bot is set to take the current lay price at 10 seconds before the scheduled start of the race.

I have the max price set to 7.4 and have a back/lay overround of 120%/80% which is quite wide but it is hard to get really close together prices on the Aussie dogs particularly if it's not the fav. The bot I am using for this doesn't have a ratio that I can set for 10% or whatever. I can reduce the overround closer to 100% but I don't think I would get many selections matched.
