Things that must NOT happen!

I got away this time but obviously I need to be more careful. It's the first time in a very long time I missed the starting time of a match I traded. Had a bet matched on Gulbis yesterday afternoon, thought the match would play Saturday. Didn't have my full stake taken and left it there. Now I checked my bets and to my surprise found a green box next to the match indicating it was in play. Luckily for me Gulbis was up a set and a break so I could close it with a nice €14 profit but this is just an unacceptable mistake. With some bad luck I could have been €70 red on this one.
