What is Double Smoothed Stochastics?
Double Smoothed Stochastics applies exponential smoothing to the stochastic calculation twice, which produces a much smoother line than a regular stochastic. The response includes the value and a trigger line.
Double Smoothed Stochastics formula
| Output | Calculation |
|---|---|
| DSS | Stochastic of an EMA-smoothed stochastic, smoothed again with EMA |
| Trigger | EMA(DSS, triggerLength) |
How to read Double Smoothed Stochastics in your code
| Signal | Meaning | Condition |
|---|---|---|
| Bullish | Smoothed momentum turning up | value crosses above trigger |
| Bearish | Smoothed momentum turning down | value crosses below trigger |
| Extremes | Stretched reading | value above 80 or below 20 |
Limitations: Extra smoothing adds lag compared with a standard stochastic. Nothing on this page is financial advice.
