Gap theory and believing "gaps always get filled" is up there...

Gap theory and believing "gaps always get filled" is up there with healing crystals and homoeopathy, but since this is the TA thread I'll post a pattern with actual scientific evidence:

"We find strong evidence in favour of abnormal price movements after price gaps. We observe that during a gap day prices tend to change in the direction of the gap... contrary to the myth that price gaps tend to get filled."

So there is evidence that after a gap up, the price will continue up in the short term - which is pretty obvious anyway. There is zero evidence for gaps having an effect on the share price weeks/months/years after the fact
