Nice Kevin,

In this case I dig out a post of Joris Schuller that can help Asis.

Best regards


Since AB 5.25 (I believe) there are two undocumented functions 
HighestVisibleValue() and LowestVisibleValue();
Joris Schueller

They replace:

fvb = Status("firstvisiblebar");

lvb =BarCount-1;//Status( "lastvisiblebar" );It now plots no matter with 
blank bars to the right… A. Faragasso

HHVMax=0; LLVMin=10000;

for( i = fvb; i <= Lvb; i++ )

{

HHVMax=Max(H[ i ],HHVMax);

LLVMin=Min(L[ i ],LLVMin);

}

with

HHVmax=HighestVisibleValue(H);

LLVMin=LowestVisibleValue(L);
