There was a fast rejection last week of the VAH, dashed line on chart, and see previous, highlighted comments. Bulls would want to see acceptance (time) at that level or higher which would be an indication that this is a new distribution higher.
In the ST, a minor (8day) control has emerged at 4493 and priced relative to that level is worth monitoring today.
Mechanically, a RTH close below the low of the 02/01 Buying Day, 4474 (dotted line) would indicate further weakness.
