The $SPX MACD turned at the lower up trending support line before it could head for the overlapping downtrend support line. So far it has stayed within the uptrend established at the March 2020 bottom, FWIW. I would be less confident should there be another attempt in the future.
Note there are 3 potential upside targets I have marked in green. I would be watching closely what happens should these be reached EOD.
