Here are the closest intraday supports and resistances for the NASDAQ and the S&P 500.
Immediate intraday resistance is S&P 500 1185.62-1188.05, NASDAQ 2006.08-2011.25.
Immediate intraday support for the S&P 500 is 1183.56-1177.68.
Immediate NASDAQ intraday support is 2002.35-1991.88. If the current decline moves under NASDAQ 1992.60, I would start to become concerned that more selling would be likely.
Whenever support is undercut it must be viewed as resistance until proven otherwise. Whenever resistance is exceeded it must viewed as support until proven otherwise.
The NASDAQ is back inside its 2017.66-1968.58 trading range, and if it moves under the 1968 level that could trigger a day of selling.
Technically, the S&P 500 never left its trading range. The range is 1193.28-1163.69. Immediate support for the S&P 500 is 1179-1163.69. The S&P 500 has a concentration of support 1169-1163. Under 1163, the next layer of support is 1147-1120, inside 1147-1120 there is a focus of support 1142-1131. It would take a close above the 1193.28 level to increase the chances for additional upside.
