Seems to me that if price keeps pushing up the upper line of the pennant, that can continue until the pattern becomes a channel or a megaphone. Eventually, the top and bottom lines do not cross. The question of time comes up.
In the NYA example you sited, I'm trying to play it back day by day, and it looks like the initial breach of the upper line happened close to the apex of the triangle, and then the early september collapse came. A few days before that, though, and it was really channel-like.
Looking at the SPX 60 minute chart, the apex right now is about during the 28th.
Do you have any opinion about 'how long' a 60 minute bar triangle might last, prior to any definitive resolution?
Thanks for the work,
