What is Ultimate Oscillator?
Developed by Larry Williams in 1976, the Ultimate Oscillator (UO) is a momentum indicator designed to capture price action across three distinct timeframes. Unlike many oscillators that rely on a single period—which can lead to erratic movements and false signals—the UO uses a weighted average of three different cycles, typically 7, 14, and 28 periods. This multi-timeframe approach aims to smooth the indicator's performance and provide a more comprehensive view of buying pressure. The calculation is based on 'Buying Pressure,' which measures the distance between the current close and the 'True Low' (the lesser of the current low or the previous close). By comparing this to the 'True Range,' the UO quantifies the strength of the bulls versus the bears. Traders typically look for three specific conditions to identify a buy signal: a bullish divergence between price and the oscillator, where the oscillator's low is below 30, followed by a breakout above the oscillator's peak during the divergence. Conversely, sell signals involve a bearish divergence with the oscillator peaking above 70. The default parameters of 7, 14, and 28 are widely considered the standard for balancing sensitivity and reliability. Practical tips include using the UO in conjunction with trend-following indicators to avoid 'catching a falling knife' during strong downtrends, as oscillators can remain in oversold territory for extended periods.
Signal Types
Bullish Divergence
Occurs when price makes a lower low but the UO makes a higher low. For a valid buy signal, the UO low should be below 30, followed by a breakout above the divergence high.
Bearish Divergence
Occurs when price makes a higher high but the UO makes a lower high. For a valid sell signal, the UO high should be above 70, followed by a breakdown below the divergence low.
Overbought/Oversold Levels
Levels above 70 are considered overbought, while levels below 30 are considered oversold. These levels are used as prerequisites for divergence signals.

FAQ
Why does the Ultimate Oscillator use three different timeframes?
By incorporating short, medium, and long-term cycles, the UO reduces the volatility and false signals common in single-period oscillators like RSI or Stochastics.
What are the standard parameters for the Ultimate Oscillator?
The default parameters are 7, 14, and 28 periods. These represent the short, medium, and long-term components of the weighted average.
How do I confirm a divergence signal in UO?
Larry Williams suggested waiting for the oscillator to break above the peak (for bullish) or below the trough (for bearish) formed during the divergence period to confirm the entry.
