$SPX Wed tried to rally off the open with a 10/20 SMA cross but failed at same point right after lunch yesterday, 3171. 
Sellers could not get this down to 3130, LOD at 3136 turned into a bullish reversal at EOD, close 3169.94. 
50/200 SMA cross coming your way on Thur open. https://t.co/rMXDUO1i9u
