Falling wedge

In a falling wedge, the two lines that form the price boundaries slope downwards and converge towards each other, but the degree of slope is greater in the upper boundary than in the lower boundary. As the convergence point approaches, the price action tightens with progressively lower highs and lower lows, but with the degree of lowering of price highs exceeding that of the price lows.

Falling Wedge

This is an indication that despite increased efforts of sellers in the market, they are not able to push prices downwards in tandem with the net sell positions. This continues until a point arrives when sellers back out of the asset and buyers fully take over, causing a bullish break of the upper price boundary.
