Hello,
 
You are wrong.
You definitely CAN access day/date/dayofweek in 
array !!!
 
dday = Day();
ddow = DayOfWeek();
 
for( i = 0; i < BarCount; i++ )
{
   // access day in loop :
   something =  dday[ i ] 
;
   somethingelse = ddow[ i 
];
}
 
And you can do what you need also without any 
loops.
 
Instead of:
 
expiry = 
IIf(DayOfWeek()==5 AND Day() > 14  AND Day() < 
22,True,False);
 
Write:
expiry = 
IIf(DayOfWeek()<=5 AND Ref( DayOfWeek() < 2, 1 ) AND Day() > 14 
 AND Day() < 22,True,False);
 
Best regards,Tomasz Janeczkoamibroker.com

  >Gary,Thanks for the suggestion, but I cannot 
  make it work. Seems to me this would require recursion which is not allowed 
  with AB functions or it requires a loop for which I cannot find non-array 
  functions such as Day, Date, DayOfWeek.Signed 
  Stumped.--
