Of course that you CAN. Recursion needs either: a) a loop Value1=0; Value2=log(Close); for( i = 1; i < BarCount; i++ ) Value1[ i ] = Value1[ i -1 ] + Value2[ i ]; b) or AMA / AMA2 http://www.amibroker.com/f?ama Value1 = AMA2( Value2, 1, 1 ); c) or CUM (this one is limited to simple "cumulation" while above two are universal) Value1 = Cum( Value2 ); A must read: http://www.amibroker.com/guide/h_understandafl.html Best regards, Tomasz Janeczko amibroker.com ----- Original Message ----- From: "Mike" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, May 22, 2008 10:32 PM Subject: [amibroker] Re: General query about cumulating values for indicators > Nope, you're not alone. > > The topic pops up, in one form or another, every couple of weeks or > so.
