I would suggest looking at the initial stops and making sure you are not setting them too tight. How do you decide when to put on a trade? Also what triggers an exit? Those factors will tend to be more important than the actual stocks you choose, since most stocks will trade with the market. Anyway, good luck.
OK, i went back and looked at the first post and I see you are entering based on levels. Essentially, you are buying when a stock breaks resistance, reverses from support or pulls back to old resistance. Not my style but it might work. I would not limit myself to long only, but it's your money.
