Question regarding efsInternal and the inv() function

[goodsz]

Hi I have a question regarding using the inv() function inside an efsInternal call function. Say I want my indicator to do calculations based on a 5 min chart when I'm using a 1 min chart. Something like this:

function main(){

var myStudy0 = ema(10,efsInternal("myFunc", 1,close(inv(5)),open(inv(5)));

}

function myFunc(y, closeP, openP){
var x = closeP.getValue(0)...openP.getValue(0);
return x;
}

Now it seems to work, but the values I'm getting from the indicator is different on a 1 min chart than a 5 min chart. From my understanding the code should work efsInternal passes a series of objects based on 5 min data and the efsInternal function does calculations based on the 5 min data.

Any help would be greatly appreciated. Thanks!

hi please read my post below first.

i have attached a picture showing two charts the top one a 5 min charts and the bottom one a 1 min chart. At exactly 10 am on the cursor window you can see the two values the indicator "test2" is giving is totally different.

Hello Goodsz,

When you want a series created by efsInternal() to be based on an external interval, pass the interval as the last parameter with inv(). The other series that are being passed as parameters do not need to reference inv().

Try something like the following.

var bInit = false;
var myStudy0 = null;
var myStudy1 = null;

function main(){

    if (bInit == false) {
        myStudy1 = efsInternal("myFunc", 1, close(), open(), inv(5));
        myStudy0 = ema(10, myStudy1);
        bInit = true;
    }
    
    
    return getSeries(myStudy0);
}

function myFunc(y, closeP, openP, syminv){
    var x = closeP.getValue(0) - openP.getValue(0);
    return x;
}
