[amibroker] Re: Repetitive Statements with FOR (?)

["kavemanperth" <gkavanagh@xxxxxxxxxxxxx>]

you could try this, who knows it may work :) or give you a starting 
point at least

tot = ???;
color = 4;

for(i=0; i>19; i++)
{
 if ( tot[barindex()-i]<3 )
 {
  color = 3;
 }
 else
 {
  if( tot[barindex()-i]>3 && tot[barindex()-i]<5 )
  {color = 6;
  }
 }
}
