Never mind I find a way to do so:
Code
vars Prices[3];
vars smas[3];
function run() 
{
	StartDate = 20200710; 
	// My Assets File
	assetList("AssetsFXCMLite");
	int cnt=0;
	BarPeriod = 1440;
	while(loop(Assets)){
		asset(Loop1);
		Prices[cnt] = series(priceClose());
		smas[cnt] = series(SMA(Prices[cnt],10));
		cnt++;
	}
	asset(Assets[0]);
	PlotWidth = 600;
	PlotHeight1 = 500;
	PlotHeight2 = 500;
	int i;
	for(i=0;i<cnt;i++){
		plot(strf("%s",Assets[i]),Prices[i],NEW,BLACK);
		plot(strf("sma for %s",Assets[i]),smas[i],0,BLUE);
	}
}
