yesterday the 2120 level was not holdable by bulls so at the end of the day we had SPX500 printing an .
Of course my recommendation is NOT to sell this kind of market, for to me that is a buy only one.
If you are long SPX500 you may consider taking your profit as a pullback is coming.
If you are out of this market, then you have just to wait for a resistive candle to enter long at a bargain price.
PS: Same story on US30 .
