$SPX - instructions for reliably determining a profitable trade bias direction for swing trading
- long or short -
based on the current trending slope direction of
the S&P 500 Net Advance-Decline Breadth line's 50-day simple moving average

** replaces the prior sticky post #16579 and #21530 **

link above is:

the daily chart for end of day review, since the Advance-Decline
Breadth line only updates once a day after the market closes

the chart also displays -

SPY daily price bars in real-time, with 21,2 Bollinger Band
$SPX daily price bars with 21,2 Bollinger Band
$SPX daily price bars with 50,3 Bollinger Band

* when the S&P 500 Advance-Decline Breadth line oscillates between
the 50,2 Upper Bollinger Band and the Lower Bollinger Band, the
US equity market is behaving in what is customarily considered a healthy market
that is routinely balancing bearish and bullish sentiment

VS.

long-duration violations of the Advance-Decline Breadth line's
Upper or Lower Bollinger Band represents an actual
unhealthy control by --

the bullish sentiment
( when above the Upper BB for a long duration of more than 17 trading days )

OR

the bearish sentiment
( when below the Lower BB for a long duration of more than 17 trading days )
