I agree with most of the things you say. I've worked in finance for the last 9 years. But to nitpick, the latency issue has got nothing to do with dealing rooms, which are rooms where traders, salespeole, quants and support staff sit. A human trader sitting nearer to Bloomberg's servers isn't going to make more money because they see the news 1us faster than someone a bit further away. The fully automated stuff is where the milliseconds matter, and the data is analysed and the trades made on servers that are not on the floor / dealing room. They are, as we've both said, in a machine room or even an exchange's hosting facility, close to their own servers. My point was simply that you won't get an improvement in "real time trading abilities" by scrapping / moving / doing whatever you like with the place where the humans sit. It's all about where the machines that run the algorithms and execute the trades are located. And that is not a dealing room (for big players at least).
