"On the other hand, all the leagues have significantly lower average hotness in the first half compared to the second half, so maybe it’s not just the NBA that has a boring first half problem." This seems to be a misconception. It

That's like asking a marathon runner why he doesn't just hop in a car. I use many languages. I use C# to knock out a GUI. VBA for a bit of spreadsheet work. Q/KDB+ for database/functional work. R for stats. All of t

How did we ever survive without them, before boost showed up? I seem to remember doing just fine. They are a symbol of the useless bloating of C++, a language trying to be all things to all people. A half-assed halfway house between mana

They have no real reason to exist. At best, they are syntactic sugar (auto_ptr), at worst they actually encourage poor design (shared_ptr). They are basically a crutch for programmers who grew up with managed languages and are afraid of r

There are some very good answers to that question. Related to that question, I still fail to see any advantage to using shared_ptr, weak_ptr, unique_ptr, auto_ptr, etc. If you are doing C++ right, nearly everything should be allocated on

VAT is paid on the difference between what you obtained a good/service for and what you sold it on at. The clue is in the name - "value added". You can even get a refund if you make a loss. A transaction tax would be charge

True enough, I was discussing direct market access. If you're going through a third party, it's up to you to vet them and make sure they are trustworthy. I agree almost word-for-word with Optiver's submission on payment for

You're still not getting it. You send your messages on a private link to the exchange. Then the exchange processes them (either puts an order in the order book) or matches a trade, and only then publishes that this has happened on the

Fine, I'll attempt to parse through your example. "Rather than buying Wigets-R-Us at $100/share, the HFT slips in with a, say, $99.99 offer to the seller, and offers you $100.01." So, 2 possibilities, you don't say,

You have no actual idea how a limit order book works do you?

Google and read up about "adverse selection". You are wrong, a retail investor/trader should never (ever) place a limit order. You have negative expectation on those orders, since you are (on the whole), slower and more naiv

Liquidity isn't a function of time, it is a function of relative time between the predators (arbitrageurs) and the prey (market makers). If the predators are much faster than the prey, liquidity will disappear since the market makers

And you've merely tried to change the subject. Something can't be front-running if it happens after a publicly disseminated market event. Understood? Flash orders = front running. Trading ahead of client flow = front running.

By the way, this is an awful, awful idea that you hear quite a lot. Think about what would happen. What incentive would a participant have for placing an order early in the one minute interval? If you can't cancel it, you're a si

Dark pools exist because these "real investors" you speak of are muppets. If you're a market maker out in the big bad world you are exposed to adverse selection risk - i.e. you're up against smarter, better informed or

Wtf? An example of latency arbitrage is say, two identical fungible securities listed on different exchanges. An order arrives causing the price on one exchange (A) to spike up (the event), you react after that event and buy the securit

You'd best look up the definition of "front-running". Reacting to an event the fastest makes you the quickest behind-runner, but you're still behind. Not front-running at all. Where did you even learn this term? Are y
