[Metastockusers] expression must contain only constant data

[chrismontgomery1966@xxxxxxxxx]

"This variable or expression must contain only constant data."
=============
peak1:= Peak(1,Fml("MACD Histogram"),5);
peak2 := Peak(2,Fml("MACD Histogram"),5);
peakbars1:=PeakBars(1,Fml("MACD Histogram"), 5);
peakbars2:=PeakBars(2,Fml("MACD Histogram"), 5);

Ref(H,- peakbars1 ) > Ref(H,-peakbars2) 
AND peak2 > peak1
===============
I am trying to determine if there is a bearish divergence
between Price and an indicator. 

Interpretes as follows: There are two peaks in the Histogram
the latest one is lower that the second ( prior ) one. While the
highest high price is higher than the prior one.

This is where the error occurs.
Ref(H,- peakbars1 ) wants a constant.

Any way around this limitation?

Also is it incorrect to try to use Peak and Trough functions as they 
rely on the zigzag function?

Many thanks,
Chris

{MACD Histogram}
EMA12 := Mov( C,12,E ) ;
EMA26 := Mov( C,26,E ) ;
FastMACD := ( EMA12 - EMA26 ) ;
SlowMACD := Mov( FastMACD , 9,E );
FastMACD - SlowMACD ;
