As long as I'm on the board this morning, I thought it might be of interest to expand on the info about the uses for Batman and batch jobs. I've long found it curious that many people don't make more use of this program. I've actually told Fred in the past that he should charge for it as well as IO :-)
Anyway, I thought I'd just list some of the things that I use it for to perhaps stimulate some ideas -
- Nightly generation of updated market and index timing signals
- Automated e-mail of signal changes
- Automated update of portfolio model rotations
- Automated stock and ETF alerts from drawn trendlines, support/resistance, etc.
- Capture of AA HTML output and FTP to web site
- Capture of chart PNG's and FTP to web site
The bottom line is that Fred has fought through many of the special cases involved in AB automation, and handles a significant amount of complexity for you in Batman. I'd encourage you to invest the time and think through ways that it might help your particular situation.

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.
