I am brand new to STT and stock trading, with zero experience. I joined the challenge and am on lesson 11 of the bookcamp education (paper trades)

Today I made my first paper trade and it was a disaster. I was attempting to buy 100 shares of FLJ on a small breakout, but when that didn't happen, I tried to sell (CUT LOSSES QUICKLY), but found the stock had been halted. 

My sell order didn't go through, so I tried to sell again.  Later I saw I still had an open position in the stock, so tried to close my position again, but somehow managed to short sell stocks.  At one point in my downward spiral, I had 600 open shares (short) and finally the lightbulb when on and I realized I needed to buy, not sell to close out.  I bought 600 shares and ended up with a profit of $59.00.  

Obviously, I will be paper trading until I figure out the mechanics of how to place orders and exit my positions.  I definitely learned a little about shorting today - even though that was not my intention.
