Fibonacci Retracement
フィボナッチ・リトレースメント
Technical Analysis★★★★ Upper-Int
A method using ratios based on the Fibonacci sequence (23.6%, 38.2%, 61.8%, etc.) along with the 50% half-retracement level to predict pullback and rebound targets. Because many traders watch these levels, they often actually function as support and resistance lines.
