Price movements are an effect of human action. Human action is the effect of reason and logic(which isn't always correct). Many more people come to a logical conclusion that gaps get filled, rather than astrological interpretations. That is the difference. btw, the gap might not get filled. I think it will get filled here in the next week to month especially if the volume dries up like it is. The price really is up to MM's and big shareholders. Do they believe in technical analysis or astrology more? That is the question.
