Here is a five minute bar chart of today's e-mini action. I covered my short position on the bar indicated by the pair of red arrows. During that bar the market broke above the 759 level I thought was resistance on high volume (red dashed line). Since I am still bullish looking ahead more than a couple of days, I chose to interpret this bar as a high volume breakout instead of a climax bar.
This means that I must revise by range estimate. I now think we have seen the day's low and that the market will make today's high near 771, with a reasonable chance of reaching 775. If this is correct then any reaction should amount to no more than 6-8 points (purple dotted rectangle) and should hold midpoint support (purple dotted line).
