The Ultimate Oscillator is a technical indicator that was developed by Larry Williams in 1976 to measure the price momentum of an asset across multiple timeframes. The indicator has less volatility and fewer trade signals compared to other oscillators that rely on a single timeframe because it uses the weighted average of three timeframes.

Buy and sell signals are generated following divergences. The Ultimate Oscillator generates fewer divergence signals than other oscillators due to its multi-timeframe construction.
