What Is a Descending Channel?
A descending channel is drawn by connecting the lower highs and lower lows of a security's price with parallel trendlines to show a downward trend. Officially, the space between the trendlines is the descending channel, which falls under the broad category of trend channels.
A more potent signal occurs with a breakout, which is when a security's price breaches an established channel's boundaries, either on the upper or lower side. When this happens, a security's price can move quickly and sharply in the direction of that breakout. If this move is in the direction of the prior trend, the descending channel would have been a continuation pattern. If the move is counter to the prior trend, the descending channel would have been a prelude to a reversal.
