SPX is testing the support cluster and ES made a low at 1530.75. The switch for ES is now at 1530.75. In my opinion, above the switch the target is for a test of 1593 (1597 SPX) possible 4/22/24 with S/Rs at previous intraday's highs 1562/1570.75. Below "the switch 1530.75" voids the above.
As always, the market has the last word and in due time will show me the way.
ES now trading at 1537.75.
