I’ve added a new price target (T3 at the 373.70ish support level) to my 60-minute chart of QQQ with the remaining targets unchanged (other than re-numbering the previous T3 to T4). While I still believe the R/R to being short at this time remains favorable, a solid break and/or 60-minute close below the S1 (1st support) level around 387.86 would provide an objective short entry or add-on to an existing short position.
For futures traders, /NQ (Nasdaq 100 futures) will also trigger a sell signal on a solid break and/or 60-minute close below S1 (1st support around 15942) with my initial targets shown on the 60-minute chart below.
