This is an interesting little bit from Bloomberg on HFT

  • High humidity is impeding radio transmissions Tuesday among three New Jersey data centers where U.S. stocks trade
  • It's taking about 8 microseconds longer to send information from Nasdaq's facility in Carteret to the New York Stock Exchange data center in Mahwah, and an extra 2 microseconds to send data to Cboe Global Markets Inc.'s exchange in Secaucus

That's good - means I got time for another cup of coffee, right?
