[amibroker] MACD Signal Value

["patsgreatdeals" <patsgreatdeals@xxxxxxxxx>]

I am looking to get the value of the MACD Signal line to test if it 
is over/under 0.

The code below (taken from AMIBroker MACD indicator) will give the 
the signal and I can plot it, but how do I check the value for the 
current bar?

MACDr1 = Param( "Fast avg", 12, 2, 200, 1 );
MACDr2 = Param( "Slow avg", 26, 2, 200, 1 );
MACDr3 = Param( "Signal avg", 9, 2, 200, 1 );

//MACD Signal Line
MACD_Signal = Signal(MACDr1,MACDr2,MACDr3);

//Plot it just for a test
Plot(MACD_Signal,"MACD VALUE", colorBlue, styleLine );

//Now I want to know the value of the current day
if (MACD_Signal > 0)
{
  //perform some other logic for buy/sells.....
}

Question: MACD_Signal is an array at this point (per the error in the 
AFL Editor) how to I get the current value for the current bar?
