  Function
  
  
  Hello,
   
  This is not really a limitation but a logical 
  consequence of the fact that one param allows the user to change ONE 
  value
  and this value does not depend on any 
  condition.
  
   
  It would not make too much 
  sense to implement it other way because each change of the 
  condition
  would need to reset all values to defaults which 
  would be very annoying.
   
  So I suggest to use it this way:
   
  value = IIF( Interval() == inDaily, 
  Param( "Interval (daily)", 5, 1, 50, 1 ), Param( "Interval (other)", 13, 
  2, 100, 1 ) );
   
  This way not only default but also user-setting 
  may depend on interval.
   
  Best regards,Tomasz Janeczkoamibroker.com

    As noted in the User's Guide default/min/max/step 
    values have to be a constant because the values are cached and not re-read 
    during subsequent executions.  This eliminates using something 
    like IIF(COND, x, y) to define the default value where, for 
    example, COND could be Interval(), etc.  Has anyone found a 
    work around to this limitation in Param() or have a suggestion as to how to 
    proceed?
