This is an interview of Securities Technology Monitor editor-in-chief Tom Steinert-Threlkeld by Peter Fedysnky, New York correspondent for the Voice of America.

I find it raises interesting questions. The idea of the large data warehouse storing every single trade across market poses interesting technological challenges. Not to mention that once stored, without delays, it needs to be analyzed. And that the only way to really regulate with this information is to be able to dissect trades on same instruments from different firms, trades on different instruments from the same firm, etc. Considering some of these market are not yet electronic, this seem to me like a serious challenge. Not to mention the basic fact that the sheer amount of information collected would it make it very hard to process.
