Personally, I'm long with a stop @ 5.45. I determine position size by the following 1% of portfolio/ (distance from entry to stop). If, I'm placing a position trade then my stop is 2ATR from entry, if I'm trying to place a short to mid-term trade, my stop is usually under an area of support.
Again, this is not advice or a suggestion to buy. This is just how I see the stock and what I'm doing with it.
