Rising Wedge (Upside Wedge)
A Wedge in chart often points to weaknesses in current expansion direction. It is a common reversal setup.
A Rising Wedge is a chart formation with higher high and higher low prints from swing to swing, where the high points can often be connected by a straight line (but not a necessary condition), and so are the low points. As the high points failed to expand as quickly as the low points, a break of the highest low point will lead to a quick dive towards the first low of the wedge.
