Formula
Uptrend retracement = high − (high − low) × ratio
Downtrend retracement = low + (high − low) × ratio
Ratios: 23.6%, 38.2%, 50%, 61.8%, 78.6% · extensions 127.2%, 161.8%
The levels are only arithmetic on the range you choose; picking a different swing gives different prices. Many traders watch them as areas, not exact prices, and combine them with a stop-loss.
Example: uptrend from 3,350 to 4,100

Frequently asked questions
How do I calculate Fibonacci retracement levels?
Take the range (high − low). In an uptrend each level is the high minus the range times the ratio: from 3,350 to 4,100 the 61.8% retracement is 4,100 − 750 × 0.618 = 3,636.5.
What are the main Fibonacci ratios?
23.6%, 38.2%, 50%, 61.8% and 78.6% for retracements, and 127.2% and 161.8% for extensions. 50% is not a Fibonacci ratio but is commonly included.
Do Fibonacci levels predict where the price will turn?
No. They are reference prices derived from a chosen range. Whether price reacts there is not guaranteed.
