Hi guys. Have a feeling this will be a fairly simple answer but I'm trying to understand how the indicators with multiple outputs are handles in zorro? In metatrader for example you slected the outputs with buffers and associated numbers.

I know the example code is incorrect but posting it as an example. Say I'm trying to get the MACD histogram output where MACD is in the string of outputs. Or the Stochastic K line for example.

Code
 
function run()
{
	StartDate = 20190101; // start two years ago
	BarPeriod = 15; // minutes per bar bars
	LookBack = 100; // needed for scale()
	var PredictHorizon = -3;

	set(RULES);   // generate signals
	LifeTime = 3; // prediction horizon
	Spread = RollLong = RollShort = Commission = Slippage = 0;
	
	adviseLong(SIGNALS+BALANCED+PEEK,0,
		MidPrice(0),MidPrice(3),priceOpen(0),priceOpen(-3),MACD(priceClose,12,26,9));
	enterLong(); 
}


I know this is probably a very simplistic question but I just can't seem to get my syntax right!
