Over the last week I've been dobbing using automation and everything has been fine. This morning I set up my trades as normal, but when I checked my account after the first three races which I had dobbed, I noticed that one of the dobs had lost, but the other two appear to have only placed the back bets. As it happened, the horses that I had dobbed went on to win (and I profited much more than I expected

Can anyone suggest why the other two dobs did not work as they should have, as it's baffling me!
