Excellent thread - many thanks. You have to wade through a lot of garbage on this site to pick out the gems, but's worth it
Is it true that exchanges keep a unique serial number for each customer (for compliance reasons)
Hell no. At least not that I've ever been told, heard of, or found. Some exchanges will show you the clearing firm behind orders. Some will show you the unique order id of the order you're matching against. So you could match up who you're trading against and analyze the edge on their flow. But I've never seen one where you can see the customer id on a time & sales feed.Quote from stanage:
and that hft's have access to these numbers (so that, for example, they can keep track of an individual customer's positions)
Quote from hft:
Without going into specifics on fees or products I think an individual can make about a grand a day with this setup fairly reasonably. With the experience I have, I'd probably aim for somewhere in the neighborhood of $5-10K/day on certain products...and most likely slip to about half that much...or into the red once I come across unexpected problems that I take for granted being resolved for me by other people now.
Quote from QuantWizard:
Here's my question, which is more "philosophical": Why deploy HFT strategies at all? The primary (only?) advantage seems to be speed, which is basically a technological arms race and depends less on the sophistication of the strategy itself, meaning that whatever advantage you have for the moment will surely fade away, even in the short term.
So what are the pros, in terms of KPIs (e.g. ROI, sharpe etc.) vis-a-vis say "medium" frequency trading (e.g. intraday)? Would you consider your competitive advantage in your ability to _renew_ your strategies, rather than the strength of individual strategies?
