I only comment on what you've typed. You are saying that between 11-11.15 there was a long grail and after 11.15 it disappeared? When did it disappear? If it disappeared straight after 11.15, it's possible as you have to wait for that 11.00 bar to close. If you saw a long grail from 11.00 till 12.00 and then it disappeared, that I've said is impossible. You do get failed patterns, but on 15 min TF you would not see any type grail formed within a 15 min frame, you can only see part of an earlier formation. I would say on 15 min chart grails take about 60 minutes to form a pattern.
