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);
