Lesson 1, be certain of your entry.  Stick to you guns.  Know what your entry is and stick to it.  Next lesson, Know that you got a partial fill.  So what happened here is I put in an order and didn't feel right about this play so I canceled my order but I got partially filled and didn't know it.  This happened twice.  The order I wanted and got filled.  Turns out the first two orders were good entries as I could have been profitable had I known I was in.  The third order was the bad trade as I got in the stock kept dropping so I got out at a total loss of $269.
