Be very careful to not use auto dutching on each way horse racing markets, I loaded one by mistake yesterday and lost over 200 pounds, seems to look for a book under 200 percent for 2 places and 300 percent at 3 places.Luckily I spotted it after 4 repititions if I wouldn't have spotted it would have wiped my 15 thousand pound betfair account out, perhaps I need to set the profit loss settings!
