Black Box trading

    Im curious as to why there are so many ECN bids/offers well away from the inside that cancel if the market gets close. I assume these are boxes because of the way they flash
    We all know how nice and predictable these programs are, but why build one that only cancels if close? I understand guys want to be first at a much better price if the best bid cancels, but what about the bids behind them canceling and flashing
  2. You must be talking about a polka dotted black box.

    They want to get a lucky fill for some quick free money.
  4. Free money. Nice.
  5. Someone paid $15 on size for $5 rat MCDTA in ah today. Was that the free $ you refer to?
