RCKS - yes, agree with your observations

with reliability in prior years/decades:

the current though brief hesitation pattern since last week by the McSum for
the NYSE common-stocks-only data set deserves much respect until such time last week's McO spike high for that data set is matched OR surpassed

what is setting up for that data set since last week's McO spike high and the later flattening of its McSum is a potential McSum upward failure and downside reversal until the prior week's McO spike high is again approached … based on past high reliability for the actual price outcomes resulting from this "warning":

this currently developing set up for this data set has priority in its chart evaluation merit and potential price impact over the other symbol data sets, with the exception of the NDX-100 which stands alone on its own merits
