How to use Fibonacci levels

Traders use Fibonacci retracements to find likely areas where a pullback may end and the trend may resume. The most watched levels are 38.2 percent, 50 percent and 61.8 percent. Extensions such as 127.2 percent and 161.8 percent are used to project profit targets beyond the original swing.

How the levels are calculated

Take the range between the swing high and swing low, then multiply by each ratio. In an uptrend the retracement is measured down from the high; in a downtrend it is measured up from the low. Fibonacci works best combined with market structure and confirmation, not on its own.

Frequently asked questions

What are the main Fibonacci retracement levels?

The key retracement levels are 23.6, 38.2, 50, 61.8 and 78.6 percent. The 61.8 percent level, known as the golden ratio, is the most closely watched, along with 38.2 and 50 percent.

How do I draw a Fibonacci retracement?

Identify a clear swing high and swing low. In an uptrend, measure from the low to the high; in a downtrend, from the high to the low. The levels then mark potential support or resistance for a pullback.

What are Fibonacci extensions used for?

Extensions such as 127.2 and 161.8 percent project targets beyond the original move, so traders use them to set take-profit levels when a trend continues past the prior swing.
