[amibroker] roc of macd

["trikerito" <trikero@xxxxxxxxxxx>]

Hi.

it seems that roc of a macd() like roc(macd(12,24),-3) doesnt 
function properly.

allways plot a flat line whith litle "sparks", but no correctily.

also i've tried 

P = ParamField( "Price field" );
periods = Param("Periods", 15, 1, 200, 1 );
k=Ref (MACD(5,13),-3);
j=MACD (5,13);
r= (k-j)/k;


//Plot( ROC( P, periods,absmode=True), _DEFAULT_NAME(), ParamColor
( "Color", colorCycle ), ParamStyle("Style")  );
//Plot( r, _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), 
ParamStyle("Style")  );
Plot( j, _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), 
ParamStyle("Style")  );
Plot( k, _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), 
ParamStyle("Style")  );

so
 k and j are ploted ok, but r (calculated roc) is the same than 
original roc(macd,-3), a flat line with "needles", but nothing 
similar than a roc of a EMA or other indicators.

a math bug of ami¿? ¿?something i wrote wrong¿? ¿?any soolution¿?

tia.
