The slope of the trend line representing the highs is lower than the slope of the trend line representing the lows, indicating that the highs are decreasing more rapidly than the lows.
It takes at least five reversals (two for one trend line and three for the other trend line) to form a good Falling Wedge pattern.
The resulting shape forms a gradually narrowing wedge, giving this pattern its name.
Since the price refuses to break the lower level of support, selling pressure gradually decreases, the upper level of resistance is broken, and the price breaks out and begins a strong upward trend.
The falling wedge should be taken as a strong buy signal and an indication that a trend reversal is imminent.
A falling wedge is the opposite of a rising wedge.
In this scenario, price within the falling wedge is usually not expected to fall below the panic value, ending up in breaking through the upper trend line.
During the pattern formation, volume is most likely to fall.
Better performance is expected in wedges with high volume at the breakout point.
Gaps before the breakout are also said to improve the performance.
In the uncommon scenario where a falling wedge is following an uptrend, the pattern shows a gradual decline in price. In most cases, the price will end up breaking through the upper line, continuing the prior trend.
