289.90ish on SPY & 185.95 on QQQ appear to be significant support levels that could open the door to another wave of selling if both taken out with conviction. Although I favor those levels going today or early next week, should the markets manage to recover & close today’s gap, SPY 294 & QQQ 189 as well as the intersecting downtrend lines off the previous highs remain formidable & very significant resistance. 60-minute charts below.
