Had an initial mental stop of 2.40 and let it go past it, hoping for a bounce that never came. Should have had a more concrete plan and studied the chart more carefully to know that I was buying at a strong resistance point. Now I know to be more careful with stocks that have a recurring pattern of not holding spikes and to be more careful with double-tops. This one clearly was filling a gap from previous days of selling and peaked right where the chart showed it would. Learned a lot here.
