Daily ATR on an intraday chart

[redislk]

Anyone know if we can plot a daily ATR on an intraday chart?

You can using the atr() function set to compute on daily data. For the description, syntax and examples of the function see this article in the EFS KnowledgeBase
Note also that the customATR.efs that is in the EFS2 Custom folder of Formulas is already enabled for use with external symbols and/or intervals

Alexis,

I can't find that customATR.efs in the efs2 folder. Can you point me to it?

Thanks,

The file is located on your hard drive in the EFS2 Custom sub-folder of the Formulas folder in the eSignal directory

Alex,

Thanks, I was looking for it online lol...

Anyways, I set the Interval to daily and I see that it uses that days daily info to calculate the ATR. Can I get it to calculate off the prior days daily data?

Thanks,
Mario

Use the getValue() method of the Series Object to retrieve the prior values

Alex,

I tried to add the getValue() to the ATR formula but it still seems to be pulling the data from the current day. Here is what I did.

I am trying to make this calculate the ATR based on
yesterdays daily ATR.

I added DaysBack var so you can specify how many days back
you would like the ATR to calculate on.

************************************************** *********/

var fpArray = new Array();

function preMain() {

setPriceStudy(false);
setStudyTitle("Mario_ATR");
setCursorLabelName("ATR", 0);
setDefaultBarFgColor(Color.blue, 0);
setPlotType(PLOTTYPE_LINE,0);
setDefaultBarThickness(1,0);
askForInput();

var x=0;
fpArray[x] = new FunctionParameter("Length", FunctionParameter.NUMBER);
with(fpArray[x++]){
setLowerLimit(1);
setDefault(14);
}
fpArray[x] = new FunctionParameter("Symbol", FunctionParameter.STRING);
with(fpArray[x++]){
setDefault();
}
fpArray[x] = new FunctionParameter("Interval", FunctionParameter.STRING);
with(fpArray[x++]){
setDefault();
}
fpArray[x] = new FunctionParameter("DaysBack", FunctionParameter.STRING);
with(fpArray[x++]){
setDefault(0);
}
fpArray[x] = new FunctionParameter("Params", FunctionParameter.BOOLEAN);
with(fpArray[x++]){
setName("Show Parameters");
setDefault(false);
}
}

var bInit = false;
var xATR = null;

function main(Length,Symbol,Interval,DaysBack,Params) {

if(bInit == false){
if(Symbol == null) Symbol = getSymbol();
if(Interval == null) Interval = getInterval();
if(DaysBack == null) DaysBack = getValue();
var vSymbol = Symbol+","+Interval+","+DaysBack;
xATR = atr(Length,sym(vSymbol));
setShowTitleParameters(eval(Params));
bInit = true;
}

return getSeries(xATR);

What I am trying to do is to eventually have a channel based on the prior days ATR plotted on to an intraday chart. So for example on a 5 min chart of GS I want to see a channel based on the prior days ATR. I went ahead and read thru the getValue() function and think I have applied it correctly but still do not get a result back. If anyone can shed some light on what I am doing wrong I would greatly appreciate it.

You are not getting anything because the syntax used in the return statement is invalid. This should be
return xATR.getValue(-1);
Additionally delete line 67 which is correct from the point of view of the syntax but not of the usage as the value retrieved from the series will be assigned to the variable nValue_1 only once when the bInit routine is executed [at which point BTW the value of the xATR series is still null as the indicator is not yet primed]. If you do want to use that line then you would need to place it outside of the bInit routine at which point you would also simply use nValue_1 in your return statement
Also delete line 64 as it is incorrect as is
