Got in right before the market close on what appeared to be a good entry for a gap up the following morning. Couldn't get out fast enough. I tried selling at a limit of 9.00 when it was at 9.05 but couldn't get executed and it began to fall. Five canceled limit orders later I was able to finally get out right at the bottom. Need to be quicker and set limit orders a lot lower if a stock is falling. Lessons learned.
