Quote from garchbrooks:
I don't doubt your comments at all, not one bit -- at least regarding speed.
But on the topic of security, the reality is that if you run, say, a firm in Chicago doing HFT, your employees end up interviewing everywhere else and people know stuff about other people's stuff everywhere else. The time you spend worrying about your binaries (not even source) on some other guy's server should be spent on internal employee security policies anyway. And, to top that off, some retail bozo making money independently would probably draw less attention than some firm that's doing serious volume and making serious profits.
I'd be less worried about someone hacking my server and taking my binaries because there's no way they can reverse engineer the binary and get all the changing inputs on a day to day basis without serious effort, and that serious effort would probably be better spent researching their own edge.
I believe the guy who says you have to remove, but at the same time, unless the edge prices in a slippage of 5-15 cents or so, I fail to see how retail traders can avoid getting victimized in the short run. HFT participants force the retail guy to withstand more risk, but I don't think the reward necessarily goes up. So, if you were doing like some kind of mean-variance study, the profile would look a lot worse for retail than HFT. Yet, it feels like ET has the same number of successful retail trader posters as it did in 2004, and it's a mystery to me how they are surviving.
In 2004, I remember seeing the markets price new information in such a manner that a retail trader could see the price adjust and move slowly. Now the MMs burst up and down, like before, but all the information gets compressed into much smaller "bars", to the point where some guy using "NinjaTrader" (or whatever) gets a faulty analysis without some really sobering assumptions worked into the model -- massive slippage, crazy commissions, and market orders filled nowhere near where a signal is generated.
