Ultimate oscillator
Buying pressure over three windows at once, from 0 to 100.
Formula
BP = Close − min(Low, prior Close); TR = true range UO = 100 × (4 × A₇ + 2 × A₁₄ + A₂₈) ÷ 7, where A = Σ BP ÷ Σ TR
How to read it
Above 70 overbought, below 30 oversold; Williams traded divergences against those levels.
How to use it
Reversal signals from divergences, less prone to false readings than a single-window oscillator.
