The next sell signal on QQQ remains a solid break and/or 60-minute close below the key 313.62ish support. (All charts below are 60-minute time frames).
Likewise, the next sell signal for /NQ (Nasdaq 100 futures) is still pending a solid break and/or 60-minue close below the key 12970ish support.
The next decent sell signal for SPY (S&P 500 ETF) will come on a solid break below the S2 support (uptrend line + 406 price support).
/ES (S&P 500 futures) sell signal to come on a break below S1 following the recent 60-minute divergent high. Arrow breaks denote price targets where reactions are likely. S1 = first support which is the intersecting uptrend line & 4117 price support.
These pending sell signals appear likely & imminent at this time although as I like to say, support is support until & unless broken. If/when both the $SPX & $NDX (futures and ETFs above) clearly trigger those next sell signals, and of the $VIX tracking ETNs or futures will also provide objective entries or add-ons.
