I think at some point I may have accidently changed my settings somewhere. While trying a front running bot halfway through the race all the lay prices vanish which leaves me in a no profit situation, anyone have any idea why this is happening?
Are you sure its the lay prices?
If they all vanish no ones laying so the horse has likely won?
Backers make the lay price so if they've pulled all their money it's probably a certain loser eg fallen at a fence etc - layers will then lay it to extremes and the back price can shoot out to 1000.
Conversely layers make the back price and lay lower and lower as a win seems more likely - but there is always lots of money on offer where people lay the field at tiny prices.
All part of the perils of in-running.
