I've traded my system successfully for over 3 years now (4 yrs if you include backtesting), so when I do have blowouts it's easy to put them behind me and focus on the next day (assuming the blowout was not due to poor execution).
Prior to that, I would take a big blowout by:
1) Walk around shell-shocked for a day
2) Do about 50 hammerfists on my mattress, yelling "F**K!!" each time
3) Walk around shell-shocked for another half-day
4) Vow my revenge on the market the next day.
I didn't say this worked for me. If anything, it made me into a worse trader. The only way really to move on quickly is to have a good system that can withstand different market conditions.
