[Link] Why don't people like markets?

Wow, sorry about the stupid autocorrects above.

As have been pointed out on e.g marginalrevolution.com, one reason HFT is so popular is because the minimum stock price increment is one cent. HFT might conceivably lose much of its allure if this lower bound is changed to, say, .01 cent.

I'm not convinced trading must be intelligent to provide beneficial information to the market. I'm also not convinced all HFT systems have identical systematic errors. Can you give some examples?

What is the problem with high-speed trading in your opinion? I see a lot of people wanting a Financial Transactoons Tax, but I have yet to see étaples of what it would accomplish or prevent?

Stupid Questions Open Thread Round 2

In Fabric of Reality, David Deutsch claims the double-split experiment is evidence of photons interfering with photons in other worlds.

One last roll of the dice

That would amount to convincing me that the experience which is currently happening, is not currently happening; or that an experience which previously happened, did not actually happen.

Why? What's wrong with an experience happening in another way than you imagine? This more than anything cries "crackpot" to me; the uncompromising attitude that your opponents' view must lead to absurdities. Like Christians arguing that without souls, atheists should go on killing sprees all the time.

Your model assumes a constant effect in each iteration. Is this justified?

I would envisage a constant chance of recovery and an asymptotically declining estimate of recovery. It seems more realistic, but maybe it's just me?

Secrets of the eliminati

Interesting post throughout, but don't you overplay your hand a bit here?

There's nothing that looks remotely like a goal in its programming, [...]

An IF-THEN piece of code comparing a measured RGB value to a threshold value for firing the laser would look at least remotely like a goal to my mind.

Smart, (young), ambitious and clueless -- what to do to maximize goodness?

Well, moderate as in they don't have rule of law etc. What I meant to say was that even this level of capitalism has worked wonders in dragging hundreds of millions of people out of poverty. Contrary to decades of Western foreign aid.

Smart, (young), ambitious and clueless -- what to do to maximize goodness?

Every system ever devised consists of smart people telling the dumb ones what to do. Even in feudal society with hereditary rule, the thicker-than-brick kings were manipulated by smart barons and courtiers :-P

I'd venture capitalism less so than other systems. At least dumb people to some extent get what they want in capitalism. But of course, this is one aspect of nature that's very difficult to remedy and I worry that the cure is worse than the ailment

Caveat lector: I'm reading Atlas Shrugged right now.

Generalization from fictional evidence

I meant it as an explanation of my current dismal perspective, not as evidence of anything. Sorry if it didn't come across right.
