Quote from drp7804:
I'm having a hard time getting amped up about this article. Neither BATS nor Nasdaq are hiding this information from the public... they post information about these data subscriptions on their websites and a quick google search of "bats multicast pitch spec" gives you the exact byte-for-byte detail of what they're doing. Same for Nasdaq Total-View ITCH. It costs more for those feeds, and less for lesser feeds, but I don't see how that's anymore fair or unfair than... anything else in a capitalist society.
Correct me if I'm wrong, but the fraction of traders / investors we're considering victims here are the ones who have enough market savvy to place hidden orders on specific exchanges... yet are not aware that those exchanges publish certain details about hidden orders after execution (yes?). Itâs unfortunate that those traders arenât âin the knowâ, but I think itâs a stretch to call it unfair. I think itâd be worse to add additional protective government regulation, which would impact a likely larger group of market participants. Obviously, anyone who knows how these hidden orders are handled and doesn't like it can simply vote with their feet and try a different exchange or stop placing hidden orders, etc.
