Fibonacci Ratios Calculator – Free Forex (FX) Trading Tool

Fibonacci ratio is the ratio between two successive numbers in the number series discovered by 13th century Italian mathematician Leonardo Fibonacci. The series consists of numbers such as 0, 1, 1, 2, 3, 5, 8, 13, etc, among which the third number is the sum of the preceding two numbers. Fibonacci ratios, including 38.2%, 50%, 61.8%, 100% and 161.8%, are often used in technical analysis for predicting price retracement levels or extension levels (targets).
