what is the stochastic rsi 
the stochastic rsi stochrsi is an indicator used in technical analysis that ranges between zero and one or zero and 100 on some charting platforms and is created by applying the stochastic oscillator formula to a set of relative strength index rsi values rather than to standard price data using rsi values within the stochastic formula gives traders an idea of whether the current rsi value is overbought or oversold the stochrsi oscillator was developed to take advantage of both momentum indicators in order to create a more sensitive indicator that is attuned to a specific security s historical performance rather than a generalized analysis of price change image by sabrina jiang investopedia 2021the formulas for the stochastic rsi stochrsi are stochrsi r s i min r s i max r s i min r s i where r s i current rsi reading min r s i lowest rsi reading over the last 14 periods or your chosen lookback interval max r s i highest rsi reading over the last 14 periods begin aligned text stochrsi frac rsi min left rsi right max left rsi right min left rsi right textbf where rsi text current rsi reading min left rsi right text lowest rsi reading over the last 14 periods text or your chosen lookback interval max left rsi right text highest rsi reading over the last 14 periods text or your chosen lookback interval end aligned stochrsi max rsi min rsi rsi min rsi where rsi current rsi readingmin rsi lowest rsi reading over the last 14 periods or your chosen lookback interval max rsi highest rsi reading over the last 14 periods
