Daily time-frame: as long as ES holds Support at 3989 it’s in a strong position.
ST: Last week price was rejected from the 4210 target (just below) with a chance of rejection here back to test 4063 see note 02/03. Time below that level and I would target 3965.
Mechanically, the reduce risk point is a RTH Close below 4048.50 (02/01 Buying Day Low).
