I tweaked the betfair automation bot from yesterday and set it to offset the bet by 10 ticks and to keep that at in play. I think I might be leaving money on the table though as I think I should not be greening up and leave the lays to just run their course.
This sounds silly but I think it is the right thing to do as with each race I potentially take £0.50 per race and if it goes on to win I lose £2. If I hedge it up at 10 ticks I am only making about £0.10p per race which means it takes a full days profit potentially.
Today I made a whopping £3.08 profit and that is only because the last but one race was a loser otherwise we would be looking at £5 profit.
Tomorrow I will bin off the offset and see how that pans out :D
