The Stochastic Oscillator compares a security's closing price to its price range over a given period, making it excellent for identifying overbought/oversold conditions and divergences in bounded ranges. It works especially well alongside the RSI for double confirmation of reversal zones in forex and stock markets. For best results, use Stochastic signals only in the direction of the larger trend identified by tools in our indicator guide library. Build it into a complete system by reviewing our trading strategies section.

RSI measures the speed and magnitude of recent price changes on a 0-100 scale, identifying overbought and oversold conditions — it is one of the most widely used <a href="/academy/indicators" class="text-primary hover:underline">technical indicators</a> in every market.
