Stochastic RSI runs the stochastic formula on RSI itself, which makes it the most sensitive of the standard oscillators — it reaches its extremes on dips that ordinary RSI barely registers. That sensitivity means it fires often, so it is a shortlist builder rather than a signal: the 200-day filter keeps it pointed at healthy stocks having a bad week, which is the only context where buying an oversold reading has an edge.
