In financial markets, "AB=CD" is a harmonic pattern that traders use to predict potential reversals or continuations in price movements. It's named after its basic structure: the price forms two legs (AB and CD) that are equal in time and price magnitude.

A "bullish AB=CD" pattern suggests that the price is likely to rise. Traders look for specific Fibonacci ratios between the lengths of AB and CD, typically 0.618 or 1.618, to confirm the pattern. When these ratios align, it's seen as a signal that the price may continue to rise after completing the CD leg.

However, like any technical analysis tool, it's not foolproof, and traders often use it in conjunction with other indicators and analysis methods to make informed decisions.
