How do you maintain synchronization with 2 or more symbols in multi timeframe mode?

[rcamrn123]

I have tried various techniques to maintain synchronization from multiple symbols from a higher time frame into a lower time frame without resorting to use of symbol spreads as I wish to perform various actions on each symbo, to then bring together into a unified indicator. As a simple example to highlight the issue, I have given the following code to just look at 2 symbols and find the MA of each and combining them into one indicator:-

// ###################################################################
// GLOBAL VARIABLES
// -------------------------------------------------------------------
// Used in preMain() for user selection
var aPArrG = new Array();

var xExample = null;
var myStudy1 = null;
var myStudy2 = null;
var bInit = false;

// ###################################################################
function preMain(){
// ###################################################################
// STUDY FIXED PARAMETERS

    setPriceStudy(false);
    setStudyTitle("MITst");
 
// VARIABLES
var k;

// USER SELECTION
    k=0;

// Symbol & Interval
    aPArrG[k] = new FunctionParameter( "sSymbol1P", FunctionParameter.STRING);
    with( aPArrG[k] ) {
        setDefault("$trin");
    }
    k++;

    aPArrG[k] = new FunctionParameter( "sSymbol2P", FunctionParameter.STRING);
    with( aPArrG[k] ) {
        setDefault("$trinq");
    }
    k++;

    aPArrG[k] = new FunctionParameter( "nIntervalP", FunctionParameter.STRING);
    with( aPArrG[k] ) {
        setDefault();
    }
    k++;
// ==================================================================
}    // END PreMain Function
// ==================================================================


// ##################################################################
function main(sSymbol1P, sSymbol2P, nIntervalP) {

// ****************************************
if ( bInit == false ){
// ----------------------------------------
if(nIntervalP == null) nIntervalP = getInterval();

if(sSymbol1P == null) sSymbol1P = getSymbol();
vSymbol1M = sSymbol1P+","+nIntervalP;

if(sSymbol2P == null) sSymbol2P = getSymbol();
vSymbol2M = sSymbol2P+","+nIntervalP;

xExample = efsInternal("testExample", sSymbol1P, sSymbol2P, inv(nIntervalP));

bInit=true;
// ----------------------------------------
}    
// ========================================

if (xExample != null) {
    if (myStudy1 == null) myStudy1 = getSeries(xExample, 0 );
    if (myStudy2 == null) myStudy2 = getSeries(xExample, 1 );
}

return -myStudy1-myStudy2;

}

function testExample(vSymbol1, vSymbol2) {
var MA1=ema(2, sym(vSymbol1) )
var MA2=ema(2, sym(vSymbol2) )

return new Array( MA1, MA2 );
} 

Nothing I tried can make this work in terms of synchronization when putting an external interval into the study in a lower timeframe.

Any help/guidance will be much appreciated.

Question to Esignal Development Group (as per request):-

Is it possible to synchronize 2 or more external symbols with the same external interval and plot a combined indicator so it is properly updated in the current (lower time frame) chart which is displaying a different symbol.

I have provided a simple example which does not synchronize at all and if there is a method I am missing using built in functions I would appreciate to see the coding that enables this capability.
