We've previously looked at how you can perform weekly scans on data before the week is over by including incomplete periods. From version 2.5, you can now scan on rolling weeks. (This idea was actually suggested in that last tip, thanks Owen!)

In this way, you can still perform your weekly scans early but without needing to use slightly less data for the last bar. Alternatively, by performing weekly scans offset by a few days you can get a picture of the market that no one else can see.

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


Figure 1

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

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't make a chart using rolling weeks yet. Is this something that many people 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!

I read about the rolling approach in Constance Brown's books, so personally I would like to be able to try it on charts reading. It might produce more timely signals, but people may argue that it loses the information content of the calander week's opening and closing prices.

If it's too hard to integrate into charts that's OK, Bullcharts is a great piece of software anyway.
