I use tight stops, which I adjust daily. I let winners run, but take half off when my goals hit. I only trade from my watch list and if technicals are right. I try to avoid buying when overbought or outside channel.
I've learned the hard way...
I only buy stocks that are ready to potentially move soon with tight Stop. I will take small loss quickly when it return back under the trend line or breakout point. http://treenhome.blogspot.com/2013/12/my-stock-trading-is-simple.html
