getCurrentBarIndex() does not update with each new bar even when in return statement

[waynecd]

Using :

function preMain(){
 setPriceStudy(true);
 setCursorLabelName("getCurrentBarIndex",0);
}
function main(){
 return getCurrentBarIndex()+"";
} 

As I understand it the returned value should update with every new bar but it doesn't. It is accurate when loaded but returns 0 for every new bar keeping the -1 etc. on the same bar as when the study was loaded. All new drawn bars after the study is loaded return 0.

The attached image has a red arrow where the study was loaded and the returned value is -1 instead of the actual bar index of -4. All bars after the bar under the arrow return 0.

Is this how getCurrentBarIndex() should work?

Wayne, I remember it counts down to zero (starting as a negative value to getCurrentBarIndex()=0) from the most recent bar (getCurrentBar()=0). Please try comparing with a debugPrint Statement before the return statement with both getCurrentBarIndex() and getCurrentBar().

Steve, always good to hear from you.

Your suggested test seem to confirm my original post. As new bars are formed and barcount increases after the original load, getCurrentBarIndex() then stays on 0. So I think it will only give an accurate index at the time it is first loaded.

I used a 10T interval ES #F chart & the following script:

function preMain(){
 setPriceStudy(true);
 setCursorLabelName("getCurrentBarIndex",0);
}
function main(){
    debugPrintln("BarIdx: "+getCurrentBarIndex()+" BarCnt: "+getCurrentBarCount());
 return [getCurrentBarIndex()+"",getCurrentBarCount()+""];
} 

I returned the following (I cropped out barcounts 0 through 284):

BarIdx: 0 BarCnt: 303
BarIdx: 0 BarCnt: 303
BarIdx: 0 BarCnt: 303
BarIdx: 0 BarCnt: 303
