Pivot line length

[Dhawk]

Hi, I am new to efs and trying to do something I think should be simple. I just want to have the pivot lines extend for only the last 3 or 4 bars instead of the whole chart. I know it can be done but can't seem to find an example of how to do it.

Any help is much appreciated.
Thanks

Check out drawLineAbsolute in the kb.
Good luck to you . . .

Thanks for your reply. I have spent a fair bit of time trying to get it to work with no luck. I keep getting errors. All I want to do is take the code below which draws the daily pivot, but modify it so the pivot line only displays a length of the last 5 bars. (Instead of across the entire chart)
Thanks again for any help.


function preMain() {
setPriceStudy(true);
setStudyTitle("Pivot Point");
setCursorLabelName("Pivot Point");
// Pivot Point
setDefaultBarStyle(PS_SOLID);
setDefaultBarFgColor(Color.RGB(0x00,0x94,0xFF), 0);
setDefaultBarThickness(1);


}

var bInit = false;
var xHigh = null;
var xLow = null;
var xClose = null;
var vPP = null;

function main() {

if(isMonthly() || isWeekly())
return;

if(bInit == false){
xHigh = high(inv("D"));
xLow = low(inv("D"));
xClose = close(inv("D"));
bInit = true;
}

var vHigh = xHigh.getValue(-1);
var vLow = xLow.getValue(-1);
var vClose = xClose.getValue(-1);
if(vHigh == null || vLow == null || vClose == null)
return;

vPP = (vHigh+vLow+vClose)/3;

return (vPP);
}

Hi, substitute

return (vPP);

with:

drawLineRelative(-5, vPP, 0, vPP, PS_SOLID, 2, Color.blue, "TagName");
return ;

Thanks Maxmax, The line displays exactly how I want. However it no longer displays the actual Pivot Point "value" in the Data window or right axis of the chart. Is there a way to fix that?

Sorry, but I think you need again
return (vPP);
You could choose a
setDefaultBarStyle(PS_DOT);
setDefaultBarFgColor(Color.lightgrey, 0);
Bye
