The first post was an introduction. The second was a nice overview of how to structure your trading system. It brought up points I've never thought of.

He did say more detail was coming in future posts. I'm not sure what you're expecting; this doesn't seem oriented towards developing models or trading strategies per se, but rather all the ancillary things that goes into building a HFT startup, including the execution of those strategies. Which was what the second post was about.

That is far more useful, since there is enough How-To-Be-A-Quant literature out there.
