What is an Oscillator of Oscillator?
An oscillator of oscillator is a second-order indicator: an oscillator transformation applied to another oscillator's output rather than to price. Stochastic RSI is the canonical example, a stochastic calculation run on RSI values, but the pattern generalizes: an RSI of on-balance volume, a stochastic of a money-flow oscillator, a derivative of a smoothed RSI. Whatever the pairing, the second layer reads the first layer's shape, so its extremes say the underlying oscillator is stretched relative to its own recent range, not that price itself is.
Each transformation is chosen for what it fixes: a stochastic layer rescales a sluggish input so 0-100 extremes and crossovers reappear, extra smoothing tames a jumpy one, and differencing (a derivative or ROC layer) isolates turning points in the slope. Every added layer also costs something, more lag or more noise plus another parameter set, and it moves the signal one step further from price, which is why second-order signals are usually checked against price structure before acting.
How traders use it
- To restore usable extremes: running a stochastic over an oscillator that hovers mid-range brings back 0-100 readings, fixed thresholds, and crossover triggers the raw series rarely produces.
- To time slope changes: a derivative or rate-of-change layer on a smoothed oscillator flags when its slope flips, earlier than waiting for a level cross.
- To normalize unbounded series such as volume oscillators or spreads into a bounded scale where alerts and consistent thresholds make sense across instruments.

Oscillator of Oscillator FAQ
Why use a Stochastic RSI instead of RSI itself?
When RSI spends long stretches mid-range and rarely tags 70 or 30, a stochastic layer rescales it against its own recent range so extremes and crosses reappear. The cost is noise: Stochastic RSI whipsaws more because it measures RSI's relative position, not price's, so most users add smoothing or confirmation.
Does an extreme oscillator-of-oscillator reading mean price is overbought?
Not directly. It means the first-layer oscillator is high or low relative to its own recent range. Price can keep grinding in one direction while the second layer cycles from extreme to extreme repeatedly, so bounded second-order readings are treated as timing refinements while price-based evidence carries the directional case.
