accumulate my indicator?

[gfuks1]

how can I accumulate an indicator that I wrote my self?
I wrote 2 indicatores(a,b),
1- returns a number & its working fine (indicator a).
in the second indicator(b) i'm writing now I need tow things:
1- is to add this bar indicator(a) number to the previous bar.
2 - is to accumulate all of the indicators(a) numbers until this bar.
pleas advise

accumulation...

well, you could simply create a variable and add the current indicator A to it...

for example.....

var myaccumulationvariable = 0;


function main() {

.. do my custom indicator here...

myaccumulationvariable += mycustomindicatorA;

}

now, this is a simple example of accumulation. Your code might be much more complex. If you need specific help on this, post something we can mess with (code). it does not have to be exactly your code (as it is now), but something we can modify as an example for you is the best solution..

Hello gfuks1,

I'm not certain this is exactly what you want, but it will show you how to do a cumulative return of an indicator. In this case a EMA value. The key is to use two global variables. One to store the indicator value and the other to store the cumulative sum. Use the bar state, BARSTATE_NEWBAR, to only allow the last value of the indicator to be added to the total once for each bar.

function preMain() {
    setStudyTitle("test");
}

var a = 0;
var suma = 0;
var study = new MAStudy(10, 0, "Close", MAStudy.EXPONENTIAL);


function main() {
    var nState = getBarState();
    
    
    if (nState == BARSTATE_NEWBAR) {
        suma += a;
    }

    a = study.getValue(MAStudy.MA);
    if(a == null) return;


    return (suma + a);
}
