I do not know much about the subject, but in stocks there is a saying that all "windows" (gaps) must be closed, basically meaning that if a stock gaps up or down, it will be filled in going the opposite way (ei: Gap up will go down to previous prices, gap down will go back up to previous prices). I know it doesn't happen very much at all in forex, but after the weekend opened up quite a few pairs gapped, and since have been filled. I was just wondering if this holds true to forex as well, or what?
