There is trading activity in the milliseconds-seconds horizon as well. I'm sure all the big HFT players participate plenty. These just wouldn't be considered MM strategies. Your original question was why MMs have to operate at H

by AllanHoustonSt 6y ago
I guess I would say, it depends? Existing profitable MMs aren't all equally fast. So the slower ones that trade on the same exchanges or even the same indices have to be profitably trading at a wider spread. HFT isn't a concrete

Traders (be it hedge funds, props, retail, anyone) will only "take your action" if you price competitively. You'll never get your orders filled. The open bid and ask as per whatever the exchange quotes are really the only p

The industry as a whole provides net value to the market by via higher liquidity and tighter spreads. The arms race is a necessity due to rising competition. HFTs cannibalize each other every year. People on the outside seem to think bein

You’d be surprised at how many traders and QRs in HFT (or at least in OMM) often reach for Excel. Granted this is way more common among older people in the industry. And as a technologist OP wouldn’t have to worry about writing or maintai

I continually find myself amazed with what people can do with Excel.

Which popular H1B source countries teach COBOL? I feel like the advent of cheap offshore programming came well after the decline of COBOL. Though my sense of history can very well be off.

Live tells aren’t taken that seriously or considered a significant factor outside of laymen. That said I do think the dynamics of poker change more than most other board/card/table games when going from live to online or vice vers

I remember seeing murmurings of this on reddit. Cool to see it’s a paper now, thanks for sharing.

I personally wouldn’t mind seeing the language go the “editions” route a la Rust.

Unfortunately I agree with you Jane Street's tech blog and published lecture series are great and probably the best I know of. They make for great advertising to boot. Lecture series like Jane Street's are common in larger tradi

As others have mentioned, they have ways of writing OCaml specifically to not trigger the GC or perform any excessive allocations. Helps when you have your own version of the compiler and a branch of the language itself. This is talked abo

I feel like self checkout kiosks already solve this. Commodotized Amazon Go tech is a minute improvement in convenience compared to traditional cashier -> self checkout.

Would it be possible to do this without changing how name mangling works?

Neat, TIL. In the US my only exposure to Mercari have been low budget Youtube ads that make it look like a side project from a high schooler. I guess that's marketing at work (or not at work).

Cryptography was both my favorite topic in school and the one that cemented my realization in that I wasn't good enough to do math for a living.

This is the current state of online poker. I enjoy it in the spirit of the game as a fan but it's definitely made earning potential and barrier of entry much higher. Poker stands on a net negative economy so the game is converging to

I don't think Google has it in them. Something about their vertical integration, supply chain management, cross team coordination, etc etc. They just consistently put out phones that are subpar in the daily usability and quality cont

I still think having a network of drivers all around you and being able to track the status of your ride both pre-arrival and during the ride itself makes rideshare a better product. Depending where you are those dispatched drivers can tak

Also good luck getting reasonable (or any) cab service outside of Manhattan and NW Brooklyn. It was even worse pre rideshare days. Those are the areas that would need something like rideshare more since they're both less dense with l

I think DPDK does some user-level trickery to achieve per-core caching through DMA, do you happen to know how they go about it?

Is the overwhelming debit spending vs credit spending an emotionally charged and risk averse rationale decision by the general populace or just unfortunate financial illiteracy?

People bet on chess as well, I have old colleagues who do it actively. That’d fall under this VC’s purview as well. I have hold no stigma against gambling, I used to gamble professionally. I just think it’s important to acknowledge what i
