Why do you want a loop to do this?
Code supplied already does this in two lines much faster.

Answer to your question anyway:
bi = BarIndex();
qty = LastValue( bi );
for (i = 0; i < qty; i++)

Subject: [amibroker] Re: loop counter
Thanks for the explanation. But how can i now create a
barindex(counter) through a loop. Graph1 plots the barindex. I have
tried to use (i = 0; i < LastValue(BarIndex()); i++ ) but this
generates an error.
Can you help ?
Cnt = 0;
for( i = 0; i < LastValue(BarIndex()); i++ )
{
Cnt[ i ] = i ;
}
Graph0 = Cnt;
Graph1 = BarIndex();
