[EquisMetaStock Group] Reg: Ease of Movement

[georgeabraham3]

Hi,
  
             In Metastock, while plotting the Ease of Movement indicator, under 
Ease of Movement indicator properties, we can choose the time periods, and also 
the methods, namely, Simple, Exponential, Weighted, Time series, Triangular, 
Variable and Volume adjusted.
  
             We can plot an Ease of Movement indicator with 13 periods and 
Volume adjusted. Ease of Movement(13,Vol. Adjusted).        
  
 But, while writing an exploration to find the same 13 period volume adjusted 
Ease of Movement indicator crossing over the zero line, Metastock does not 
permit the use of the Volume Adjusted method. 
  
             For example, Cross(emv(13,v),0) is not permitted. Can any one tell 
me why this is so.
 Is there any way to write a code for a 13 period Volume adjusted Ease of 
Movement crossing the zero line?
  
 Any help would be greatly appreciated
  
  
 Thanks,
  
 George
