The Fibonacci spiral is created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling, thus the radius grows proportionally to Fibonacci ratio. The main principle of using the Fibonacci spiral in technical analysis is setting the first radius as the distance between two significant extremum points of chart. I have no idea what all that means.

@dide - Yes, I saw an article the first time I heard about the Fibonacci spiral. It contained a photo with the spiral placed on top of it depicting how to compose a photo but I was confused by what they said and what was in the photo.
