This is the complete opposite of what is happening.

What you're describing is straight up hacking, and if there was as clear of a breach of the law like that, we wouldn't be having civil discussions about whether HFT is good or not.

Besides, almost nothing routes to Wall Street anymore. Especially not for stocks.

NASDAQ's trading platform is in Carteret, NJ. NYSE's trading platform is in Mahwah, NJ. Most HFT firms, if they're not already colocated in Carteret or Mahwah, are located in Secaucus, NJ.
