Yes, look how many unfilled double gaps we left behind us in SPX during last months. In SPY I see one example confirming rule where it was not 100% filled, just almost filled. Ammo, it was filled out of RTH. We can repeat it, quite probable scenarion, but gap will be no more as magnetic as "virgin" one.
None? Maybe one? By the way thanks to the moderator for deleting my post, where I actually made an important point... Anyhow...
agree, but a lot of times the ah es stops 3 points under or over spx res/supp then rth repeats in spx
