Stochastic RSI (StochRSI) is a technical analysis indicator designed to assess market momentum by comparing a security's price range to its closing price. It is used primarily to identify overbought and oversold conditions in stock markets, providing faster signals than the traditional Relative Strength Index (RSI). Unlike RSI, StochRSI moves more rapidly between overbought and oversold levels, making it useful for traders seeking timely momentum insights. This indicator supports analysis across various indices and is categorized under momentum indicators, specifically related to RSI.
