After setting it though and finding it kicking in I'm sure it seemed to place two lay bets as opposed to one (to cancel out the original back). I've also just looked at my profit and loss for today and a back bet go into play (obviously in these cases the horse never goes on to win!

I make very few trades per race, normally just one and I try and catch a trend so I'm finding the extra bets being placed more confusing than it really should be.
I still have Betangel running and I'm also sure a log file is created somewhere that I can look at ?
