If the future exits from the particular bar in question then you get a value If the bar is on or after the 4th to last day of the data, then a 4 day future does not exist If the bar is before the 4th to last day of the data, then a 4 day future does exist However I cannot see any real value to using future values unless your signal references that condition as far back in the past as you look into the future for that condition. This forward looking would I think generally be used for finding swing points where the pivot does not exist until after the price has retraced.
eg Condition = ref(occurence,4); Signal = ref(condition,-4); -- Cheers Graham AB-Write >< Professional AFL Writing Service Yes, I write AFL code to your requirements http://www.aflwriting.com On 28/05/07, Vinay Gakkhar. <[EMAIL PROTECTED]> wrote: > Dear Tomasz, > > In TimeFrameGetPrice, shift allows to reference past (negative values) and > future (positive values) data in higher time frame. > > What exactly is meant by 'future' here? > > gakkhar > > ------- Forwarded message ------- > From: "Tomasz Janeczko" <[EMAIL PROTECTED]> > To: [email protected] > Cc: > Subject: CORRECT RESULTS, was Re: [amibroker] WRONG RESULTS > Date: Mon, 28 May 2007 02:43:27 +0530 > > Are you serious?
