A Descending Triangle is a bearish chart pattern that is used in a downtrend market. It is formed by a series of lower highs and a lower resistance level. The support level will eventually be broken, confirming the sell signal. This pattern can be used to identify short-term reversals or to confirm the continuation of the downtrend.The best time to trade a descending triangle is when the market is testing the lower resistance level. Sell short when the market breaks below the lower resistance level and use a stop loss above the upper resistance level.
