Hi,

 

How about this statement, does it still require loading all bars?

 

MaxV = LastValue(HighestSince(Status("barvisible") AND Ref(Status("barvisible"),-1)==0,Volume));

 

 

thanks,
Joseph Biran

Hello,

 

Yes it does because of

statements like this:

 

Volscale*LastValue(Highest(V);

 

Combination of LastValue and Highest makes it necessary to use all bars
to calculate last Highest value from all data.

 

 

You should avoid such statements AND replace :

 

Plot(AvgVol,"",colorGold,styleNoTitle|ParamStyle("Style",
   styleHistogram|styleOwnScale|styleThick|styleNoLabel,maskHistogram),

   0,Volscale*LastValue(Highest(V)));

 

by:

 

Plot(AvgVol,"",colorGold,styleNoTitle|ParamStyle("Style",
   styleHistogram|styleOwnScale|styleThick|styleNoLabel,maskHistogram),VolScale);
