Construction
r(θ) = r₀ · φ^((θ − θ₀) / (π/2)) φ ≈ 1.618
r₀ and θ₀ are the distance and the angle from the center to the second point; Oyticker draws the spiral from the center out to one full turn beyond that point.
Use and limits
The spiral is used to look for time-and-price zones where a trend could turn, where the curve meets price. It is the most subjective of the Fibonacci tools: the result depends on the center, the second point and, above all, on the chart's zoom, because the spiral is drawn in screen space.
