Why the following does not work?

[z11]

regarding my atr sample code. Sorry I had the typo of premain instead of preMain; also bInit is initialiazed as false but null.

But my code still doest not work on a Daily Chart! hmmmm...

[z11]

function preMain() {
setPriceStudy(false);
}

var atrD = null;
var bInit = false;

function main() {

if (bInit == false) {
atrD = atr(14, inv("D"));
bInit = true;
}
var atrD0 = atrD.getValue(0);
debugPrintln(atrD0);
return atrD0

}

this debugprintln statement returns null for atrD0.

Ok Alex, I found the problem - the first few values of atrD0 are indeed null.. I should have added a check null statement! amature mistake..thanks for trying this out!
