[amibroker] how to improve loop speed

[Panos Boufardeas]

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
