The world also needs fewer* trading algorithms.

• fredkbloggs 11y ago
  Well, really, the world doesn't need any. But I'm curious why you think the world would benefit from fewer.

    Isn't there no real value added with HFT? Isn't the question then 'why don't we have fewer?'

      HFT is generally touted to provide liquidity, at the least. Of course, there are some that argue against that.

      Apparently the people doing it are gaining something from it, else as you note there would be less of it. I don't know whether it's value-creating or not as a whole; there are different types and classes of HFT operations and algorithms (including those that try to trade based on rumors and sentiment), and various arguments about who is or is not better off for their existence. Someone who wants to assert that it's harmful needs to have some kind of tally of all the benefits/profits and all the harm/losses that shows net value destruction, or at the very least a complete ethical argument. All we got was "the world needs less of this", which doesn't really do much to further anyone's understanding nor provide a digestible view on the matter.
