I&#x27;ve worked in automated option market making in the past; if I were on a jury hearing this case, there&#x27;s no way I would convict these guys of spoofing.  They are taking advantage of a feature built in to the market for purposes similar to this: hiding your intentions.  The only people who could realistically be damaged by this are professionals, retail customers will either benefit from the tiny bit of extra liquidity added by the 1 or won&#x27;t be adversely affected by the hidden AON orders on the other side.  The algo traders who complained to the SEC should be embarrassed at doing so; they should have been burned on a couple of trades, figured out what they were doing wrong and fixed their code to compensate.  Blindly stepping up your quote or order for size on a 1 lot in order to capture rebate is just foolish and anyone who can make money off you for doing so should be entitled to it.
