S&P 500 price levels to trade

[rimshot]

S&P Composite 1500 index daily Advance-Decline percentage values in histogram format --

the zero line equals the bull/bear pivot for the Advance-Decline smoothed with the 3-day SMA & 13-day EMA, and the current chart condition
as of Friday June 12 displays a mixed message since:

the 3-day is far below the zero line while the 13-day is slightly above the zero line on Friday's bounce

plus 2.79 = current value of the 13-day EMA for the Advance-Decline as of June 12
minus 34.16 = 3-day SMA value

* at its recent low, the 3-day SMA value printed a negative value worse than any seen since late 2018,
highlighting the speed and fierce quality of last week's decline by both price action and Advance-Decline internals

=============
689.77 = 21-day SMA, which bears must hold as Resistance
674.91 = S&P Composite 1500 index 233-day EMA value must be defended by bulls during future declines
669.35 = 100-day SMA
657.81 = 50-day SMA
