A double top is a bearish reversal pattern that forms after an asset reaches a high price, pulls back, and then fails to break above that same resistance level. It looks like the letter M. Traders typically identify this pattern when the price falls below the middle support level, known as the neckline. This suggests that buying momentum is exhausted and sellers are taking control.
A double bottom is a bullish reversal pattern that appears after a downtrend. The price hits a low, bounces upward, and then returns to that same support level before failing to push lower. This creates a shape resembling the letter W. A breakout occurs when the price rises above the neckline, signaling a potential shift toward an uptrend.
These patterns rely on volume analysis for confirmation. High trading volume during the second peak or trough often increases the reliability of the reversal signal. However, these formations are not foolproof. Markets frequently experience false breakouts where price action reverses unexpectedly. Trading involves significant risk, and past chart patterns do not guarantee future performance. Always use stop-loss orders to manage potential losses when trading technical formations.
