This article really makes me angry. Who does this support other than the IT industry that supplies them with 500 Million in servers, networking equipment & infrastructure?
What is this data center going to do? A grad student could design a decent database system for trades and banking. So they now have a 500 million $ data center, are they now going to use that scrape a few more milliseconds off there HFT's or the associated algorithm's? Are they going to figure out the optimal market strategy to beat there competitors? They can't possibly have enough data to fill something like that, so it has to computation power, right?

How does this contribute to society other than support an electric company? Don't give me liquidity bullshit.

Separate your banking from investing and then we can talk about how "banks" like this isn't a plague on society. /rant

Comment Re:HFT Should be illegal (Score 1) 77

A penny per share tax is a buck on a round lot trade of 100 shares to kill HFTs. The problem is I don't lose a buck to HFTs but I would lose a buck to the govt. Its just a cheesy stealth taxation plan. Blame the HFTs, rich people suck, horray for the 99% we're gonna destroy HFTs, but the only real end result is the govt takes more of my money. So a transaction tax is a great way to cause a couple orders of magnitude more damage to the economy than HFTs could theoretically ever cause.

Who's to say this money would go to the government? Don't exchanges need to pay huge amounts of money for infrastructure to support this activity? Also, isn't there a clear segregation between "normal" traffic and this high speed traffic?

This still doesn't explain the fixation on killing HFTs. So they get a "sin" tax. On what sin, exactly? nobody knows.

Because financial engineering has just been so beneficial to society... /s

WRT increasing transaction volume to make more than $1000... Remember that superman movie where Richard Pryor took all the fractional cents out of everyone paycheck, put them in a pile, and kept that substantial amount? Well HFT is like that in trades where a bunch of competing HFTs fight each other to, on long term average, determine the sub-cent price of a share priced in cents, and then, essentially, the HFT who skims off the least amount on top of the sub cent slice beats the greedier HFTs and keeps the extra skim. Well, in the movie, if Richard Pryor wanted more money, he'd have to make more transactions, make more paychecks. But Mr Pryor doesn't get to decide how many times paychecks are written per month (Weekly checks? Daily checks?), or how many people are employed... This tired old hollywood plot was recycled into Office Space, and probably many more movies. There's only like 50 movies, endlessly redone.

Ya ya ya, we all know the old skimming scheme that's become possible because of electronics controlling money. Just because there is a way to manipulate a system, doesn't make it a good thing. 21 is a good (blackjack)movie, but will still get you thrown out of a casino. There's nothing to say that these HFT's aren't skimming money from regular investors and vice-versa. That said though, why does the market exist in the first place? It's not for a bunch of machines to race to the penny.

Think about making a competitive system to determine the sub cent fractional price of shares traded at cent rounded prices. Read the wikipedia article below. You pretty much end up reinventing HFT.

Instead of sending me to a generic NP-Hard problem, I find this - far more interesting. Particularly the part where these machines submit orders and then instantly cancel them in order to find how high/low the market's machines are willing to go. I'm sure there is some very complicated algorithms(combination of networking and math) that go into finding the optimal way to beat others at this game...

I like the idea of a lot of competing HFTs from a lot of companies fighting each other in a race to the bottom to rip me off the least. Worst case is we damage the HFT ecosystem just enough that two companies get all the fractional skim and have no limits on greed because the government helpfully destroyed all the competition for them. Yes. That would be bad.

I do agree that the current competition scheme is better than an artificially created monopoly. I'm just confused why the HFT market needs to exist in the first place. Liquidity could come in from other ways(I believe). If not a tax(maybe not to the government) on only HFT, then why not a random delay (like say 10 second average)? Wouldn't that preserve the market while removing any possible gain that could be made this millisecond?

We (as a country) always make the worst possible decision, so this is probably what we'll implement.

Comment Re:HFT Should be illegal (Score 1) 77

The easiest way to "get rid of" HFT is to fix decimalization. Back when we traded on eights thats too wide to make money on a HFT strategy, and if we allowed millionth of a penny trading quotes that would narrow bid/ask resulting in too little money generated by HFT. Decimalization seems to be almost the perfect pricing system to result in massive HFT strategies, so if you really hate HFT (and WHY?) then just fix the pricing structure so its not profitable anymore. Rather than playing games with legal enforcement of favored or disfavored behavior, simply make disfavored behavior unprofitable. I suppose the opposite solution of going big would work just as well, fine we'll only trade stocks on dollar values now no fractions of a dollar.

Don't forget that it was possible to game they system in different ways when they traded on fractions. Changing the decimal system seems a bit overkill(also, I'm still a bit confused how that wouldn't create further issues?) when a small tax on ultrafast trades/a small delay on the stock exchange end would solve the problem created by these HFT machines.

Comment Re:Myths of Security? (Score 0) 216

Your comment isn't very intelligible. Are you confusing cryptography with computer security, perhaps?

I know they are two separate topics (albeit related to some extent), I was just kinda generalizing that there is always a flaw in the system, obviously a buffer overflow doesn't have anything to do with cryptography... and I forgot to hit the "Post Anonymously" button.

That statement does not pertain specifically to mod chips or software, but is a general statement about such goods.

Hardware, batteries, etc that are counterfeit can and have caused injury and death. Counterfeit medicine, vitamins, and supplements have caused sickness and death. Counterfeit toys and children's clothing contain dangerous chemicals, lead based paint, are missing flame retardants, or are made of flammable material.

Absolutely counterfeit good are bad for the market and for public health, but what he was arrested for ("felony tinkering" not for attempting to misrepresent his product as the real thing) will always lead to cries of absurdity.

This was something that was discussed in Bruce Schnier discussed in his book ( ).
