Have a maximum loss level for the day, the week, the month and for the overall system. Once you have hit that level, go and hit your paperwork. Go and try and quantify the quality of your set-ups and find out which ones work the best and which are falling over. By stopping trading you are likely to still spend the down-time thinking about trading which will help you when you step back up to the plate. After you have analysed your strategy and system sufficiently - go and find a cheap game online that wont hurt you - and hit the tables. this is good stuff
