Hello,
Move ALL array functions OUTSIDE of loop!
Inside the loop there should be only NON-array functions.
// THIS MUST BE OUTSIDE THE LOOP !!!!!!
Q=Param( "% Change",1.50,.25,14 ,0.25);
Z= Zig(C,q ) ;
HH=((Z<Ref(Z,- 1) AND Ref(Z,-1) > Ref(Z,-2)) AND (Peak(z,q,1 )
>Peak(Z,q,2 )));
LL=((Z>Ref(Z,- 1) AND Ref(Z,-1) < Ref(Z,-2)) AND (Trough(Z,q,1 ) <Trough(Z,q,2 )));
dist = 0.5*ATR (20);
for( i = 0; i < BarCount; i++ )
{
// ONLY THIS should be inside the loop
if( HH [i]) PlotText( "HH"+ "\n"+H[ i ], i, H[ i ]+dist[i], colorGreen );
if( LL [i] ) PlotText( ""+L[ i ]+"\nLL", i, L[ i ]-dist[i], colorRed );
}
Nothing more is needed.
Best regards,

Subject: [amibroker] how to improve loop speed
Hi
I am curious to find out how to make a loop to run from firstvisiblebar
I think I need to write something like the following . but I don't know how
lvb = Status("lastvisiblebar");
fvb = Status("firstvisiblebar");
for( i = 0; i < ??? ; i++ )
{
I have an example here that executes very slowly in live intra day chart
Can you tell me please how I can correct this example ?
Q=Param( "% Change",1.50,.25,14 ,0.25);
Z= Zig(C,q ) ;
HH=((Z<Ref(Z,- 1) AND Ref(Z,-1) >
Ref(Z,-2)) AND (Peak(z,q,1 )
>Peak(Z,q,2 )));
LL=((Z>Ref(Z,- 1) AND Ref(Z,-1) < Ref(Z,-2)) AND (Trough(Z,q,1 )
<Trough(Z,q,2 )));
dist = 0.5*ATR (20);
for( i = 0; i < BarCount; i++ )
{
if( HH [i]) PlotText( "HH"+ "\n"+H[ i ], i, H[ i
]+dist[i], colorGreen );
if( LL [i] ) PlotText( ""+L[ i ]+"\nLL", i, L[ i
]-dist[i], colorRed );
}
Plot(C,"",IIf(C>O,colorGreen,colorRed),styleCandle);
Thank you
Panos
