SPY and $NYA price bars vs. 50-day EMA vigilance in
the context of the $NYAD daily histogram chart -

* 50-day EMA vigilance is constructive for the bullish case,
as of the close Wednesday September 9, 2020

* the NYSE cumulative net Advancers minus Decliners line has declined to test the 50-day SMA from above
and
has now sharply bounced from the most recent A-D line low

SPY now has multiple consecutive days/weeks
achieving daily closes below its 21-day SMA

will intraday support at the 55-day EMA eventually fail to hold for future daily closes when tested from above by intraday price action?
