Hi b
The data is directly accessible via the MetaStock plugin. We already have this operational for listed securities and requires no maintenance from your side (apart from the occasional click of one menu item). Also, we fully classify all of the listed companies into meaningful markets/groups/sectors/watchlists (see http://www.premiumdata.net/support/amibroker.php#securitylayout for a screenshot of the layout). The way our database maintenance works, you don't have to worry about "junk" building up. We remove codes that have changed due to code changes or delistings (there are a several hundred code changes each year on the US markets). In terms of AmiBroker integration, I think we'll have three different AmiBroker databases that are fully maintained: 1. Currently listed stocks 2. All delisted stocks 3. All listed and delisted stocks One thing that really needs careful attention with a delisted security database is the issue of code reuse/overlaps since AmiBroker can only accept one instance of any given code. We'll be getting around the code reuse/overlap issue (ie where codes are used multiple times throughout history by different companies) by using a numbering scheme at the end of the codes (eg. ABC1, ABC2, ABC3 for companies that three delisted under the code ABC). Best regards, Richard Dale.

How does one import the data into Amibroker? Is it by importing csv files, or is there a direct route? Getting delisted stocks for research made it worth the hassle to get CSI data into AB. After working through lots of problems, I finally settled into a two database solution. Once a month or so I would do a full history export from CSI into a virgin Amibroker database. That database was just used for research. It was never updated. The second Amibroker database of CSI data was just for the past year and it was updated regularly. Over time "junk" would build up in this database due to ticker changes etc. About once a month, I would delete the daily database, create a new one, and start fresh. A nicer solution would be most desirable. b _
