Smoothed Momentum indicator is a smoothed momentum.
There are five inputs:
- Momentum period - calculation period
- Use smoothing (Yes/No)
- Smoothing period
- Smoothing method
- Applied price - Momentum calculation price
Calculation:
- If Use smoothing = Yes
Momentum = MA(Mom, Smoothing period, Smoothing method)
- otherwise
Momentum = Mom
where:
Mom = 100.0 * MA / PMA
MA - SMA(Applied price, 1)
PMA - SMA(Applied price) Momentum period back
