While a break back below the 595-596 support is the ideal entry or add-on to an existing short position (as previously stated), a case for an objective short entry can also be made here at the downtrend line off the recent highs on /NQ & QQQ. The dotted lines/arrows show how any marginal new high soon would be an extension of the existing divergences. 60-minute charts below.
