If the market does decide to pullback further then keep in mind that 800 is solid support and buyers could emerge there. Also, I have drawn in a fib retracement from the lows to the highs of the recent rally and the 50% retrace comes in around 768. This level should be the line in the sand to determine if the rally we have seen is for real. If price pulls back all the way down there then thats where the bulls will make a stand if they still believe.
For Wednesday, I want to be neutral and see where the market trades to determine my intraday bias. The pivot is at 839.75 so that will likely be a good area to see if the buyers support it or not. Below that area and I would be expecting the market to retrace back a bit more into the lower 800s on the SPX. Trade safe.
