Bought at the close and held overnight in anticipation of a gap-up. The gap-up happened as expected but I tried to use Booktrader one-button-trade for the first time ever to sell into the spike and couldn't get it to work correctly. While trying to figure it out, the stock panicked and I ended up selling at the bottom of the panic. Very frustrating loss due to technical difficulties and not realizing that a morning panic could set in so quickly.
