Bruce, thanks for the afl. It comes at the most oppurtune time when I'm considering creation of many sectoral indices. However, rookie that I am, I am not able to figure out how to use the AFL. I would appreciate a step-by-step detail on how to use it, including where to copy the afl, where to store the csv list of tickers etc., and how to run it. Can the afl be pointed to a watchlist instead of a csv file of tickers?
Thanks again.

Quick update - I've added a Free Code module and Free Code article to
AmibrokerU called ListAvg. For those who need for an equal weighted
average of a list of tickers, the Code module provides a function that
implements the result in a single call. If you are interested in the
background on the need for this function, and the problem with other
types of index and list averages, the article should be of interest.
Here are the links (sorry they are long, I'll fix that soon) -

As we prepare to open up subscriptions to AmibrokerU soon, I've received
some questions about what types of free and subscription content that we
plan to add. In general, we will offer "lite" of "subset" versions of
premium code and articles available in the subscription sections.
ListAvg is an example of that. It implements an equal weighted average
of a CSV list, and is effectively re-balanced daily. Plans call for a
full-featured routine in the subscription section called WtMixRebal that
implements weighed averages that can be re-balanced at different periods
or based upon a signal. This module is useful for index averages as
well as portfolio modeling of a weighted list of tickers with shorting
and margin with a fast, single function call.
In addition to educational articles, I'm going to try to cover broader
topics of applications, with examples, that I've found useful. In that
spirit, the next topic will be about connecting to Excel and
manipulating spreadsheets, charts, and data. That may seem a little
odd, but there are many uses for such an interface - both for input to
and output from Amibroker. For example - summary bar charts, command
button trading control, etc. More later ....
