Hey Blue
I agree that most of the time they come down and close the gap, but not always. After the crash I bought Bingham Petroleum around a buck. It was trading around $18 before the fall. One day it had a gap up in the mid $3 range and I sold waiting for the gap to close, but it never looked back. The climb continued, but I wasn’t going to chase it. I think it was eventually acquired by a larger company. I lost a bundle by not staying in.
I don’t know much about charts, but not sure I see a gap. Thursday opening lower than Wednesday close, and Friday opening about even with Thursday close.
