Investors watch trading volume and other momentum indicators alongside descending channel patterns to better gauge when to open and close trades.
Buying an asset in a downtrend can be a risky maneuver because most investors struggle to spot reversals and as the trend deepens traders take on deep losses. In instances like these, being able to spot descending channel patterns can help traders avoid buying in a bearish trend.
In a downtrend, the price action forms a series of lower highs and lower lows. A descending channel is drawn by joining the lower highs and the lower lows using parallel trendlines. The main trendline is drawn first where two or more lower highs are connected. Then a parallel line, also called the channel line, is drawn connecting the lower lows.
The price action inside a descending channel continues to move south as bears sell on any relief rallies to the main trendline.
When the price reaches the channel line, bulls believe that the price has become attractive and they buy, but the bears are in no mood to allow the bulls to have their way. They sell when the price reaches the main trendline and the trend remains down.
The trading inside the channel is usually random but bound between the two parallel lines. A break below the channel indicates that the bearish momentum has picked up and that could result in a spike down.
Conversely, a breakout of the descending channel suggests a possible change in trend. Sometimes these breakouts result in a new uptrend, but on other occasions the price action forms a range before resuming the downtrend.
