What is Ultimate Oscillator?

The Ultimate Oscillator, from Larry Williams, combines buying pressure across three timeframes into one value from 0 to 100, weighting the shortest window most. It was designed to reduce the false signals of single-window oscillators.

Ultimate Oscillator formula

Output	Calculation
Buying pressure	Close − min(low, previous close)
Average	Sum of buying pressure ÷ sum of true range for each window
UO	100 × (4 × A1 + 2 × A2 + A3) ÷ 7

How to read Ultimate Oscillator in your code

Signal	Meaning	Condition
Overbought	Pressure heavily on the buy side	`value` above 70
Oversold	Pressure heavily on the sell side	`value` below 30

Limitations: The original signal is a divergence followed by a breakout, so raw threshold crossings alone miss the intended use. Nothing on this page is financial advice.
