A decent quality rising wedge has formed from the early March low, and that broke down last week. That could be a bullish underthrow of course or the wedge could be expanding. If wedge resistance is hit again today then at minimum I will assume the wedge has expanded, and redraw the wedge support trendline accordingly.
