trade timing signals - using Advance-Decline line tools

[rimshot]

S&P 500 index daily charts:

* position long while the A-D line moving averages are rising and
consider exit when any one of the four A-D line moving averages is declining, and

strongly consider exiting long when A-D line declines below the 50-day sma
for multiple days


position short while the A-D line resides below the 50-day sma and above the A-D line's daily 50,2 lower Bollinger Band

( the A-D line's lower BB is the 0 line for the 50,2 %B and the 50-day sma chart location is the 0.50 line for the 50,2 %B )
