Yes, I posted the link because it was very good describing the types of gaps and why they occur. Do I agree with the summary OPINION at the end? No, it`s very noncommital.

I have gone on record, on this board, as posting, first, a very high percentage of gaps fill. My proof is all the many charts I`ve seen through the years. Pull up some two year charts (just a random time frame selection)for yourself on some of your favorites. Second, I have never said all gaps fill and have even given an example (a company buyout) on this board. Third, I have said, I believe the .85 would fill and have also said that IMO the .41 wouldn`t on this board. For some bizarre reason, this puppy keeps getting hit with selling volume when news breaks.

When RMBS was at 46, you`d never believe the gaps at the beginning of the year were going to fill, but after getting slashed in half, it gapped down again today and is 5-6 bucks away now. Kinda makes you wonder.

Why a gap fills. It`s a void, an absense of trading. At one side of a gap is a support/resistance point, at the other side is a support resistance point. If you had trading prints in place of the gap, it would trade just like an ordinary chart. The gap on the chart just gives it that little bit of a emotional edge to it is all IMO. It`s not just because there`s a gap. What are companies doing at any given time to happen to cause a gap to fill (see RMBS for example). Once you`ve broken that last support/resistance point, and you`ve hit the void, it fills.

As I`m typing, I`m wondering why do all the charts show me an intraday at 1.05 and quote of 1.21 for a high today?

Thanks for the good questions, and your willingness to have a discussion.

Regards.
