Donchian Study statement

[edhecht]

Hello,

I want to create a complex statement(shown right below) but it doesn't work. The reason why I want one line is so I can change the 27 to a counter and change the parameters over and over drawing lines.
temp= study.getValue(DonchianStudy.BASIS,26,27);



Instead of doing the following in separate statements:
TenkanSen = new DonchianStudy(9, 0);


var nTurningLine = TenkanSen.getValue(DonchianStudy.BASIS);

Can someone assist me here?

Hello Manesh,

I don't think you will be able to do what you need all in one line. At any rate, you should use the new Donchian studies.

var xBasis = null;

function main(nIndex) {
    if (nIndex == null) nIndex = -27;
    if (xBasis == null) xBasis = middleDonchian(9);

    return xBasis.getValue(nIndex);
} 

You can use the "nIndex" variable as a formula parameter to change through Edit Studies the value from the series you want to plot. The example above moves the plot forward by 27.
