Poor risk/reward management. But also poor execution. I got into the stock at the support level, hoping it would give me a run back up. The stock had ran up 100% and was holding in the 80% area. So the pattern looked good. And at the time, even my entry was good. But it dropped too quickly for me to get out without taking a major hit. Again, it later came back and I had about $100 profit before it dropped again. Should have sold seeing the weak price action. I also experienced poor liquidity.
