Based on the premarket data from US500, I could tell today the ranges for SPX were most likely gonna be small and contained as the Standard deviation from Vwap were still small at the open and didnt expand even when price touched the area where 3 standard deviations from vwap was. I sold 2 contracts of 6870/6865 puts for $0.50 premium when price was below vwap which is the blue dotted line. My stop loss was going to be two closes below the red horizontal ATR Level (6891.2). I was able to close both contracts around 8:10 AM PST. for $0.10.
