I don't actually know much about the subject, however in stocks there is a saying that windows (openings) must be closed, basically meaning that when a stock gaps up or down, then it'll be filled in going the opposite manner (ei: Gap upward will return to previous prices, gap down will probably go back up to previous prices). I know it does not occur very far at all in forex, but following the weekend opened quite a few pairs gapped, and since have been filled. I was just wondering if that holds true for forex too, or what?
