displacing an efs?

[bigtee]

How would I go about modifying/adding code to displace an indicator forward by one or more bars? For example, below is part of the code for the Keltner channel efs. What changes would be required?

function main(nInputLength, nConst) {
if(nInputLength == null)
nInputLength = 20;
if(nInputLength <= 0)
nInputLength = 20;

var Factor = 2.5;
if (nConst != null) Factor = nConst;

var vHigh = getValue("High", 0, -nInputLength);
var vLow = getValue("Low", 0, -nInputLength);
var vClose = getValue("Close", 0, -nInputLength);
if(vHigh == null || vLow == null || vClose == null)
return;

var vHLC3 = 0;
var vHminL = 0;
var i;

for(i = 0; i < nInputLength; i++) {
vHLC3 += (vHigh[i] + vLow[i] + vClose[i]) / 3;
vHminL += vHigh[i] - vLow[i];
}

vHLC3 /= nInputLength;
vHminL /= nInputLength;
vHminL *= Factor;


return new Array(vHLC3 + vHminL, vHLC3, vHLC3 - vHminL);
}

The answer is probably a little tricker than just looking at that piece of
code - can you attach the whole file?

yep. here is the whole file if it helps.

If you want to displace the plot replace the 0 in the lines below with the desired negative offset (ie -1, -2, etc)
var vHigh = getValue("High", 0, -nInputLength);
var vLow = getValue("Low", 0, -nInputLength);
var vClose = getValue("Close", 0, -nInputLength);
I think that should do it

Thanks Alex, that does the trick nicely. Using a -3 dispaces forward by 3 bars.
