Here is a five minute bar chart of e-mini day session trading. As you know I think the market's rally yesterday represented a clear rejection of prices below the 930 level. I believe that it is important to trade only in the direction indicated by the last rejection the market makes of some support or resistance level. In this case the support level was the low of June 3 which was at 922.50.
If the market is indeed headed upward from here I think it will not trade below the midpoint of yesterday's day session at 936 (red dashed line). This is also the low of a trading range which has been established since yesterday's high (green rectangle). I am sticking with my range estimate for today of 935-950 (blue rectangle).
