Rising wedge

In a rising wedge, the two trend lines that form the wedge pattern slope upwards and converge towards each other, but the degree of slope is greater in the lower boundary line than in the upper boundary line.

Rising Wedge

As the two lines converge, the price action of the asset tightens with progressively higher highs and higher lows, indicating that despite the efforts of buyers to push prices higher, they encounter resistance until a point arrives when the buyers tire and sellers take over, causing the asset price to breakout below the lower price boundary.
