RSI on the last three Volume bars

[wawuki]

Hi everybody,

it shouldn't be such a problem, but somehow I can't get it working:

I would like to add the Volume of the last three bars
(3Vol = volume()+volume(-1)+volume(-2))

and do an RSI on it
(RSI of 3Vol )



Who can help, or knows a link, or can tell me if this does not work !?

Best Regards

You should be able to easily do that with the RSIEnhanced.efs that is in the Library subfolder of Formulas. Open it with the Editor and replace the lines
var dClose = close(0);
var dPrevClose = close(-1);
with
var dClose = volume(0)+volume(-1)+volume(-2);
var dPrevClose = volume(-1)+volume(-2)+volume(-3);
That should return the RSI of the sum of the last three volume bars

FWIW once EFS2 is released with version 7.9 which is currently in beta testing the formula will be much easier to write as shown in the example below
Alex

function preMain() {
    setPriceStudy(false);
    setStudyTitle("RSI of 3bar Vol");
    setCursorLabelName("RSIvol", 0);
    setStudyMin(0);
    setStudyMax(100);
}

function main() {

    return rsi(14,efsInternal("volsum")); 
}

function volsum(){

    return (volume(0)+volume(-1)+volume(-2));
}

Thanks Alexis, it is working now.
