I had never thought of this before.

HFT provide liquidity. With enough of them, you really don't need a NYSE any more. After all, they're doing the same thing the exchange does.

Now all the attention to HFT makes a lot more sense. The logic never added up, but the politics obviously do.

Thank you.
