On Thursday after opening with as huge gap-up the market sold off hard in the afternoon. NQ dropped down to just above 18,000 strong support, previous high from January 24th, now should provide a bounce point.
However, if that gets broken on Friday it would trigger a lot of stop-loss selling that could tank NQ down to the next support, 17,380
Intraday inflction price level is at 18,400, now acting as resistance, support at 18,000
