HFT is not front-running. Front-running is a form of trading on non-public information.

  Some forms of HFT work by getting information from other exchanges before you, then front-running on price differences.

    That's not what front-running is.

    This is arbitrage, not front running. Front running requires not-public information.
  • denotational 6y ago
    Front-running usually refers to a fairly specific scenario in which a brokerage or fiduciary executes orders as principal prior to dealing on behalf of their client so as to benefit from a market movement they anticipate will be caused by the client's orders. This is categorically not what HFT firms are doing.
