I read about the rolling approach in Constance Brown's books, sopersonally I would like to be able to try it on charts reading. Itmight produce more timely signals, but people may argue that it losesthe information content of the calander week's opening and closingprices.

If it's too hard to integrate into charts that's OK, Bullcharts is a great piece of software anyway.  ]]> Wed, 13 Apr 2005 23:53:49 +0000 http://www.bullcharts.com.au/forum/forum_posts.asp?TID=190&PID=713#713 Scanning on rolling weeks : Thanks Peter....for a great job... http://www.bullcharts.com.au/forum/forum_posts.asp?TID=190&PID=711#711 Author: Seahorse

We've previouslylooked at how you can perform weekly scans on data before the week isover by including incomplete periods. From version 2.5, you can nowscan on rolling weeks. (This idea was actually suggested in that lasttip, thanks Owen!)

In this way, you can still perform your weekly scans early but withoutneeding to use slightly less data for the last bar. Alternatively, byperforming weekly scans offset by a few days you can get a picture ofthe market that no one else can see.

Figure 1 illustrates the effect that the different options have. Theletters represent days of the week, and the red boxes show how a weeklyscan would group these days together to form weekly bars.


Figure 1

When "Use rolling periods" is selected, the groupings are shifted sothat a complete group is finished on the last bar being scanned(typically the the latest data available). Weekly bars are thencalculated from these groupings, which are then used for your weeklyscan.

These options are also available for monthly, quarter and yearly scans and work in an equivalent manner.

(Before anyone asks, this is only for scans. Unfortunately you can'tmake a chart using rolling weeks yet. Is this something that manypeople would find useful?)

I'll be on holidays soon, so there won't be any tips for a few weeks.
Au revoir et à bientôt!
