Fibonacci retracement
Also called: Fib
Horizontal levels drawn at fixed ratios between a range's low and high.
In practice
An optional overlay on Aureus charts, off by default. The levels matter to the extent that many traders watch them — a convention, not a law of nature.
What it is not
Not a forecast, and not a claim that the price will react at any level.
