A double-top chart pattern is a technical analysis pattern that occurs in financial markets, such as stocks or cryptocurrencies. It is considered a bearish reversal pattern and is formed by two consecutive peaks of similar height, with a trough in between. The pattern resembles the letter "M."

The double-top pattern suggests that an uptrend is losing strength and a potential trend reversal may occur. It indicates that buyers have failed to push the price higher after the first peak, leading to a decline and subsequent rally to a similar peak level. The failure to break above the previous high signals a shift in market sentiment from bullish to bearish.

Traders and analysts often look for confirmation of the double-top pattern by observing a break below the support level, which is the trough between the two peaks. This breakdown is seen as a signal to enter short positions or take profits on existing long positions.

As with any chart pattern, it is important to consider other technical indicators and factors before making trading decisions based solely on the double-top pattern. Confirmation through price action and volume analysis is typically sought to increase the reliability of the pattern.
