What is a Fibonacci Calculator?
A Fibonacci calculator generates key retracement and extension levels based on the Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13...). These levels, particularly 38.2%, 50%, 61.8%, and 161.8%, are widely used by traders to identify potential support, resistance, and profit targets.
The 61.8% ratio (known as the "golden ratio") is considered the most significant level. Fibonacci analysis works best when combined with other technical indicators like price action, moving averages, or volume.

Frequently Asked Questions
Draw from swing low to swing high in an uptrend (or high to low in a downtrend). The calculator shows levels where price often retraces before continuing the trend. Enter trades near these levels with stops beyond the next level.
The 61.8% level (golden ratio) is considered most significant as it appears frequently in nature and markets. The 38.2% and 50% levels are also reliable. Deeper retracements to 78.6% often precede trend reversal.
Extensions project where price might go after breaking the swing high/low. The 127.2% and 161.8% levels are common profit targets. Use extensions to set take-profit orders in the direction of the trend.
Partly self-fulfilling prophecy—many traders watch the same levels. Also, the golden ratio appears throughout nature and may reflect underlying patterns in human behavior and market psychology.
