Mike,
This may sound stupid, but I have 2 questions
1)what is a batch manager?
2)why is running batch files important?
Thank you
ACE

I believe that it means that the categorization of symbols is limited to a tree of depth 2 rather than the 4 actually available from ICB (http://www.icbenchmark.com/icb_structure.html). Unless you're trying to run a strategy against the less refined granularity, it should not be an issue. Even so, you could probably create a watchlist and add all the symbols from the more refined categorizations into it, thereby creating, in effect, the less granular categorization.

This data structure can store whole numbers in the range of -2,147,483,648 through 2,147,483,647. If the volume figure exceeds the maximum figure, an "overflow" condition occurs and the volume wraps around to a negative number. For example, the NYSE Composite index had a volume of 3,745,144,031 on Friday 3 May 2008 which significantly exceeds the amount. This is why negative volume is shown on days of very high volume in those few high-volume indexes.

In the "Divide Volume By" field enter a number (eg. 10 or 100 or 1000 - right now 10 seems to be effective across all the US markets for the time being).

If you would like this to be implemented within AmiBroker please login to the AmiBroker Feedback Center. After logging in then click here to show issues #636 and add a comment requesting a permanent solution to the issue.)
