Double Top & Double Bottom
Technical AnalysisReversal patterns formed by two roughly equal peaks (double top) or troughs (double bottom), confirmed on a break of the level between them.
A double top is a reversal pattern where price rallies to roughly the same high twice, failing to break through on the second attempt, signaling exhaustion of an uptrend. A double bottom is the mirror-image bullish pattern — two roughly equal lows that mark exhaustion of a downtrend.
Both patterns are typically confirmed only once price breaks below (double top) or above (double bottom) the low or high formed between the two peaks or troughs, since two similar highs or lows alone don't guarantee a reversal.
