When you put on a trade....set a .50 stop....In my own trading, everytime I ignore this, it costs me thousands...and when I do it, I stop out of a few trades early, and it's a head ache. I've come to realize that I can make back a .50 loser fairly easily, and even take several .50 losers and still make money. Taking a loser of several points is no fun. So I choose to get out, reevaluate, and If I still like the trade, I get back in and risk another .50. If I get two losers, I give up on the stock and move on.
What would I do, mark the trade from here, and if it goes .50 against, stop out and reevalutate.....but that is just the opinion of this humble trader!
