I do not know much about the topic, but in shares there is a saying that all windows (gaps) has to be closed, basically meaning that when a stock gaps up or down, then it'll be full of moving the opposite manner (ei: Gap up will go down to previous prices, gap down will probably go back up to previous prices). I understand it doesn't occur very far at all in Foreign Exchange, but after the weekend started several pairs gapped, and since have been filled. I was just wondering if that holds true for Foreign Exchange too, or what?
