Also it is very important to keep a trade journal. Along with the details of the trade record the rules used and most importantly your emotional state after the trade is closed. Also did you break the rules and why? Record your mental state. Are you elated, bummed, depressed, ticked-off or whatever. Vent and use strong language if you need to. I chuckle when I look at my trade log of two years ago. I was very emotional and would freeze up, unable to place a trade. I now trade with a clear level head.
Also, I took the AUD/USD long on the BO yesterday and closed it out before noon CST today when it stalled out. At the time I thought it might go higher but was happy to book the profits and wouldn't be upset if it later soared.
