On TradingView, oscillators are technical indicators that measure market momentum, strength, or potential reversals by fluctuating between set levels (like 0-100 or -70/+70), helping identify overbought/oversold conditions or trend shifts. Key examples include the Awesome Oscillator (AO) for trend confirmation, the Stochastic Oscillator for momentum changes, and the Ultimate Oscillator (UO), which combines multiple timeframes to reduce false signals, all designed to provide actionable insights beyond just price.
