I am really scratching my head on this one. As the race entered the final furlong I put in a £100 lay of the current leader Comedy Act at 1.15 which didn't get matched and as the horse was being headed I moved onto the next race.
I am scalping the next race when I notice my bank balance had significantly increased. It was £270 higher than it should be so I examined my P&L and found this.
The above shows that I placed my back for the eventual winner, French Hollow at 20.17 which is before the start time but I never entered the market pre race. Furthermore when I put my lay into the market whilst in play, the grid was empty. Anyone would have noticed £270 on one selection with £100 red on all the others. I have been trading horses for four years so I know when a grid is empty!
In the past four years I have occasionally left back or lays in the market and paid the consequence but have always remembered what stupid mistakes I had done. However with this race the only time I entered the market was to put in the lay.
I have changed my password for peace of mind but know that it couldn't be anybody hacking in unless it was my guardian angel deciding that I deserve a few more pennies in my account.
