Here's an exponential average that is time-related.  However, it needs
minute bars, not ticks.  


{  Calculates a Daily XMA on Intraday Data with a calculated length
   equivalent to an N-day MA.  Adjusted by the BarInterval - must
   be in minutes, not ticks.   DayLeng =1 is essentially an 8-hour XMA. 
   DayLeng may also be fractional days: .13 = 1 hour }


inputs: DayLeng(5) ;
vars: Factor(2/ (DayLeng * (390 / BarInterval) + 1)), Price(0),
MyXavg(0) ; 

IF BarNumber = 1  Then  MyXavg = C 
	Else MyXavg =   Factor * C  +  (1 - Factor ) * MyXavg[1]  ;

Plot1 (MyXavg ,"Xavg") ;
