saving an array in Global Memory? How To?

[airborn3823r]

Looking for some help with a thorny issue.

Is it possible to create an array in global memory (as in setGlobalValue() ) populate it with data, reload the script and then reference the values set in global memory while the script reloads?

Why would I want to do such nonsense? Basically to solve the problem of data syncronization between two data sets that are on the same timeframe but one dataset does not have a data record for each bar (specifically the "ES #F=2,1" & "$TRIN,1" placed on a RTH time template chart). The $TRIN dataset has numerous holes that I can fill if I can create a global array and then trigger a reload of the study and reference the "fixed" TRIN data in the global data array.

If anyone can point me to a sample or docs that shows ...
- How to create the array
- How to add values to the array
- How to retrieve values from the array

I can take it from there as long as someone points me in the right direction.

I'm pretty sure I can solve this problem using FileI/O but Global memory sounds like a better solution if it's possible.

Thanks,
Rick

Rick,

Yes it can be done, here is a link to my fileshare area that has some array examples. I'll post something tomorrow about the setting ang getting of the global arrays. It is pretty straight forward, but I can't put anything together tonight. link

Hello Rick,

You can pass arrays to the global space with setGlobalValue(). Here's a code example that will demonstrate some of the basics. It's not a direct solution for the routine your attempting to code but it should help get you going. You might want to visit this link, which covers the core functionality of the Array Object.

function preMain() {
    setPriceStudy(true);
    setStudyTitle("set/get global array ");
    setShowCursorLabel(false);
}

var myArray = new Array(3);
myArray[0] = 100;
myArray[1] = 200;
myArray[2] = 300;
var bDisplayed = false;

function main() {
    if (getCurrentBarIndex() == -10) { // occurs during initial load
        setGlobalValue("DataArray", myArray);
    }
    
    if (getCurrentBarIndex() == 0 && bDisplayed == false) {
        var globalArray = getGlobalValue("DataArray");
        if (globalArray != null) {
            debugPrintln(globalArray);
            debugPrintln("Array Length = " + globalArray.length);
            bDisplayed = true;
        }
    }
    
    return;
} 

Here's an example of the formula results in the output window.
