Re: [amibroker] optimization

["Tomasz Janeczko" <amibroker@xxxx>]

Hello,
 
There is a bug in optimize feature that has an 
effect that at the optimization
setup stage d1 becomes an {empty} value for a 
while and MA crashes with {empty} period, 
so one need the following <FONT 
face=Tahoma>work-around for using MA in optimization 
formula:
 
d1 = optimize( "%D days",10, 2, 30, 1 
);
 
d1 = LastValue( IIF( IsEmpty( d1 ), 1, d1 ) ); 

 
buy = close >ma (close, d1) ;sell =close 
<ma (close, d1) ;
