Lost Discipline

Terrible day's trading (Tuesday 20th Jan...not sure what's up with the date settings on this site). Not because of the one loss, but the manner which I lost. Broke pretty much all my rules. Didn't move up my stop for fear of stopping myself out too early. When eventually did get to my stop (which I hadn't kept on the books!) I waited...cost:17 pips instead of the 6 I intended on risking (GBP/USD). Perhaps the slip in discipline is caused by my latest month-long winning streak...
