Automation bot
i would wager that there are tons that have little success, many that have moderate success and a very closely monitored few that are in the category that you are referring to. sadly, no one would divulge such a bot as the edge that it had would render it useless within days/weeks of being released into the wild.
For what it's worth, I'm sure you've had a ton of frustrations with your own bots, i have too!! however, you start to identify approaches that are doomed to failure and thus avoid, as well as identifying friction within races which allow you to capitalise on the mechanics of such an interaction. I'd suggest you focus some attention on high back book%'s or low lay book%'s, as well as monitoring IR runners where the gap between the back odds and the lay odds is way out of kilter. Altho this will get you 30% of the way twds a decent performing bot, the final 70% will always be a moving target and one that observation should tighten up (did the runner go from 3 odds to > 100 inside 3 seconds, did it hit 1.01 and spiral out past 2 etc,etc).
hope this helps in terms of the realities of finding the best bot -it will come from you in the end.
