Orginal RSI?

[tshirtdeal]

Looking for the original RSI, not the Wilders version...

It would be
RSI = 100 - (100 / (1+RS))
RS = n period average of up closes / n period average of down closes


with no smoothing... is this available somewhere? Can it be easily coded somehow from this if not?


avgDown.Set((avgDown[1] * (Period - 1) + down[0]) / Period);
avgUp.Set((avgUp[1] * (Period - 1) + up[0]) / Period);
}

double rs = avgUp[0] / (avgDown[0] == 0 ? 1 : avgDown[0]);
double rsi = 100 - (100 / (1 + rs));

Thanks for any help!

Hi RT,

You can work from the existing RSI and save a copy. Click Tools > Edit NinjaScript > Indicator > Double click RSI.

Right Click > Save as.

I'm not sure about the specific changes you would have to make but hopefully a community member can offer input here. If you wanted without smoothing, this is the Avg plot.
