"Mysterious algorithm..."
I suppose that's technically correct-- we don't know how the algorithm works. But they make it sound like they have no idea to whom the algorithm belongs. If your logging can't get you this information (the bot's owner), I have no hope for the security of the exchanges.
If this kind of thing is a problem, then read your logs, visit the 'offending' party, and Do Something About It.
- dfc 14y agoRead your logs? The people that identified the algo are just looking at quotes coming in from different exchanges. What logs do you think they can look at?
- Jupe 14y agoSo, requests come into the trading system and there's no tracability? No credentials? No security? I'm not very religious, but heaven help us if this is the state of the Wall Street automation!
- yummyfajitas 14y agoThe SEC and individual exchanges have access to the full non-anonymized feed. Other market participants, such as nanex, only get the anonymized feed.
- theorique 14y agoEach participant is identified to the exchange (or ECN or ATS) by a MPID (market participant ID), but individual quotes on an exchange's limit order book are not tagged.
- rorrr 14y agoTrades are pretty much anonymous, only the exchange itself knows who the participants are.
- delinka 14y agoI guess I missed that the exchanges aren't commenting on this story. Now I suspect they haven't commented for many (if any) of these kinds of stories.
