The September contract looked bound for a minimum 18.230 when the closing bell rang yesterday, having stalled just a tick above that Hidden Pivot’s sibling midpoint, 18.105.  A push above the resistance would all but guarantee a follow-through to 18.230, but it will take at least 18.470 to revitalize the bull trend on the lesser charts. On the hourly, no less than 18.845 would be needed over the near term to send bears diving for cover. Alternatively, my worst-case number is 17.350, where a garden-variety trendline from the hourly chart comes in today.
