Rising wedge pattern indicates "the final struggle."

The curvature of the lower trendline being greater than that of the upper trendline means that the speed of the lows rising is much higher than that of the highs, gradually showing signs of weakening upward momentum, leading to small-scale reversals that continue the larger-scale decline.
A true bottom formation also requires multiple tests and validations to confirm. Generally, a descending wedge indicates a bottoming process, an ascending wedge suggests a trap for more buying, and a descending wedge signifies that the downward momentum is exhausted, leading to a bottom.
