The primary information edge an asset manager has is that they have large enough order that it is not immediately consumable. This will have a price impact. So, if they take the HFT price on offer at a market, the HFT will lose money as the price will go against them.

Most of the algos I'm thinking about there are designed to minimise market impact. They do this by spreading the order over time and/or space (venues) as well as by balancing passivity and aggressiveness.

There is not a terrible lot that is written that is unbiased as most have a particular POV. Market microstructure textbooks are perhaps the healthiest place to start ;-)

Thanks a lot for sharing those bits of knowledge! I'll look into that, have you ever considered writing a book? ;) I added your blog to my long must read!

I love HN for such moments, out of a blue a post on a superinteresting topic AND a knowledgeable person who doesn't mind answering some questions.
