A Hedge Wall has a similar impact for individual stocks as the Volatility Trigger™ for indices, and can be thought of as the point where realized volatility is expected to start increasing (the expected percentage range over a period of time based on historical prices with 68.3% confidence). Like any other of our major key levels, when Hedge Walls increase, it is a bullish sign for the market and it is a bearish signal when they decrease.

Hedge walls also function as strong support/resistance but the main thing making this level special is how it is predictive of future volatility behavior with statistical significance. Above the Hedge Wall, we might usually expect to have more success with mean reversion rather than momentum strategies.
