Stochastic RSI (StochRSI) is a technical analysis indicator used to support stock market prediction by comparing a security's price range to its closing price. StochRSI is unique in that it focuses on market momentum and is good at reading overbought and oversold market conditions. StochRSI differs from other technical indicators, such as the Relative Strength Index (RSI), because it moves from overbought to oversold prices faster than the RSI.
