You can smooth any data serie with any other calculation, to smooth the RSI with the Ehlers Super Smoother, you can do it like this:
```
//John Ehlers’ “Super Smoother”, a 2-pole Butterworth filter combined with a 2-bar SMA that suppresses the Nyquist frequency:
Period = 10
Data = RSI[14](close)
PI = 3.14159
f = (1.414*PI) / Period
a = exp(-f)
c2 = 2*a*cos(f)
c3 = -a*a
c1 = 1 - c2 - c3
if barindex>Period then
 S = c1*(Data[0]+Data[1])*0.5 + c2*S[1] + c3*S[2]
endif
return S
```

14 periods is the RSI calculation period, while Period=10 is the one for smoothing. You can change/adapt them for your own needs, there are no real good ones.

The above code only returns 0, displaying a single horizontal line.

I copied & pasted the code as is.
