Ultimate Oscillator

DEFINITION of 'Ultimate Oscillator'

A technical indicator invented by Larry Williams that uses the weighted average of three different time periods to reduce the volatility and false transaction signals that are associated with many other indicators that mainly rely on a single time period.

BREAKING DOWN 'Ultimate Oscillator'

This is a range-bound indicator, which means the value fluctuates between 0 and 100. Similar to the RSI, levels below 30 are deemed to be oversold, and levels above 70 are deemed to be overbought. Transaction signals are derived by finding situations where the price is going in opposite directions than the indicator. Once this divergence has been identified the trader will wait to confirm the transaction by using other technical indicators.
