Fibonacci Retracement

คำจำกัดความ

Fibonacci retracement is a technical analysis tool that uses horizontal lines at key Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%) to identify potential support and resistance levels during a price pullback. These levels are derived from the Fibonacci sequence and are widely used to predict where price corrections may end before the trend resumes.
