Right now the BPNYA weekly is at 46.49. If we went up to 52 or 53, the top might be cemented. A wonder ramp would do that.
As for the BPSPX, I agree it could have a ways to go. However, we're not sure how many charts will become bullish if the SPX hits 910 or 920. We might get to 60 on the BPSPX weekly if that happens, and the full stochs on the weekly might approach the 80 level on the 14,3 setting.
The way this market is behaving, we are not going to get that pullback to 843 you're looking for before we take out this week's highs. If that's the case, I think we have to look at any further advance as a terminal wonder ramp that may cement a top for many months.
