How Do I Put an SMA on a Spread Differential on the Same Plot/code for TS?

[clbradley 10]

How can I put a simple moving average on a spread differential indicator on the same plot underneath price, so the SMA isn't the SMA of the price, but of the spread differential indicator? The SpreadDif and SMA have to be in the same code too, don't they? This is the code for TS's Spread Differential:

 

inputs: DataSeries1( Close of data1 ), DataSeries2( Close of data2 ) ;

 

Plot1( DataSeries1 - DataSeries2, "SprdDiff" ) ;

 

and for the Mov Avg 1 line:

 

inputs: Price( Close ), Length( 9 ), Displace( 0 ) ;

variables: Avg( 0 ) ;

 

Avg = AverageFC( Price, Length ) ;

 

if Displace >= 0 or CurrentBar > AbsValue( Displace ) then

begin

Plot1[Displace]( Avg, "Avg" ) ;

end;

 

Just not sure how to paste these together to put them in the same code. Thanks for any help.
