Hello, the momentum of an SMA is the MOM indicator … so MOM20 is the momentum of an SMA20. Is there also an exponential version of this for the EMA? Or is the RSI20 (50/50) ultimately the momentum of an EMA20?

Momentum is just the difference of the closing price or any moving average now and x periods ago. So, for an EMA :
```
momEMA = exponentialaverage[periods](close) - (exponentialaverage[periods](close))[x]
```
The momentum indicator pre-programmed in PRT is not for a SMA ! It is only the difference of the closing price now and the closing price x periods ago ! So, in this case :
```
mom = close - close[x]
```

Oh I see? But when you compare the PRT momentum with an SMA of the same period, it seems to indicate exactly what the SMA is doing.

I don’t think so. Just display them all in a chart and compare the values manually.
