Fibonacci retracement calculator
Enter a swing high and low to get the Fibonacci retracement levels (23.6% to 78.6%) and extension levels (127.2% and 161.8%) for forex, crypto, shares or any market. Free, no sign-up, nothing leaves your browser.
For a move up, retracements are measured down from the high; for a move down, up from the low. This is a calculator, not advice.
What Fibonacci retracement is
After a strong move, prices often pull back part of the way before carrying on. Fibonacci retracement levels mark common pull-back points as a share of the move: 23.6%, 38.2%, 50%, 61.8% and 78.6%. The ratios come from the Fibonacci number sequence, apart from 50%, which traders simply find useful.
How traders use the levels
Traders watch the levels as places where a pull-back might stop, and some use the extension levels beyond the swing as possible targets. Like any chart level, they are guides, not promises: price can slice through all of them. They are best used alongside other analysis and a stop loss.
