Yeah you lost. If you didn't sell at 7 you will probably wait until you are WAY DOWN to sell. that is the mistake most traders make. Often traders run it up so that it can go down farther. So instead of going short back at 5.15 you buy sell at 7 then go short until it hits like 4$ and take profits again. No offense but you should not be trading stocks. If you want to just buy and hold you should look into mutual funds instead. You will just lose even more money trading stocks.
I bought around 5 then i closed at about 7 and bought puts. Like I said you should probably just buy mutual funds so someone else can do the trading for you. You will lose money every time with your method.
