Hi, I found this in the document:
"Multicore training is now possible with scripts located in the StrategyFolder given in Zorro.ini."

My strategy is in the StrategyFolder, but it seems not using more cpu resource(30-40%), which is the same with 2.25. What is the problem? My code is like this:
Code
function run(){
	if(is(INITRUN)) NumCores = -1;
	set(PARAMETERS+LOGFILE+PLOTNOW); //+PLOTNOW
	#ifdef USE_MONEY_MANAGEMENT
	set(PARAMETERS+FACTORS+LOGFILE);
	Capital = 2000;
	#endif
	if(Train){
		StartDate = 20190202;
		EndDate = 20200802;
		NumWFOCycles = 3;
        ...
