They mentioned a lot of colos, but you can actually lease space in the NYSE building itself. You don't get much faster than parking your server next to the one

  From the article: One reason the high-frequency traders can beat others to the punch is that they often locate their computers in data centers run by the exchanges. The New York Stock Exchange, for example, moved its computer infrastructure last year to a facility it built in Mahwah, N.J., where it also leases space to trading firms. It can command premium prices for that space because close physical proximity means fast access to the exchange's raw trading data. Most other market participants don't see that data until milliseconds later, after it's been consolidated and combined with information from other exchanges.

    Interesting! The mention of the NYSE wasn't in the article when I read it. Good to see they updated it.

    This underscores the weakness of TFA. "often locate their computers" really should read "always locate their computers" in data centers run by the exchanges. Any high frequency trader that does not is, well, decidedly second tier or worse.

  being colocated dosent mean anything if your infrastructure sucks. e.g. what switch(s) you use, which PHYs/transeivers are used, what NICs you use, what kind of cables (fiber/copper) and what kind of hw/sw stack you run on. You might be surprised there`s 10s of nanosecconds difference between a twinax 10Gb copper cable, 0.5M 10Gb SR fiber and a 2M 10Gb SR fiber cable... which does make a difference. The differences between different vendors of NICs.. etc etc. ...this aint no FB/Google/blah.1M.requests.a.minute datacenter - its the latency not the thoughput that matters.

    What's funny is that this matters even less than Facebook.
