the falling wedge can be one of the most difficult chart patterns to accurately recognize and trade. When lower highs and lower lows form, as in a falling wedge, a security remains in a downtrend. The falling wedge is designed to spot a decrease in downside momentum and alert technicians to a potential trend reversal. Even though selling pressure may be diminishing, demand does not win out until resistance is broken. As with most patterns, it is important to wait for a breakout and combine other aspects of technical analysis to confirm signals.
