I’ll add that most hft firms are trying to move to longer time horizons. Some with great success, some mixed, some not at all. There’s not much unclaimed pie left in the hft world

I don’t know why you think I’m saying TA works. The only thing I’ve said is that HFTs are by and large not responsible for trading away those inefficiencies

sub-minute opportunities are absolutely not all that exist, in many ways it’s the opposite. The hft opportunity space is extremely competitive, and much more zero sum than the mid/low frequency space. A relatively small set of players

The existence of players that generate high-sharpe consistent returns is a sort of empirical proof that the market is not actually random (although these tend to be relatively short term trades, I.e. < 1hour holding periods, turnover por

HFTs generally consider shorter timescales (both in the feature set and the forward horizon) than human TA would lean on, and make tremendous use of microstructure information rather than outright price movements. Having said that, “let’s t

These changes reduce the amount of instructions you need in the first place - less stack shuffling with more registers and push2/pop2, less register shuffling with nondestructive operations

I have yet to experience an issue watching media from where I reside when in the states (or when visiting Europe) than the other way around. Given, I live in Asia and haven’t spent a ton of time in Europe so maybe that explains it. You shou

Something that shocked me when I left the USA a few years ago was how aggressively region locked everything is outside of the states. More than half the times I’ve tried to find something it’s “oh, this isn’t available in your region”. “Oh,

If everybody is exactly 350us slower, then it’s still the same game. Iex also offers a variety of (dark) order types that can pull back without the 350us delay if iex believes the incoming flow will be toxic

Buying the 10 year and hedging all risks down to the two years is equivalent to just buying the two year. I think most other banks tried to get interest revenue from something other than going turbo long long-term treasuries? Or just accept

Not sure if or what the chance was, but fmax(x, 0) only requires checking the sign bit instead of doing a full floating point comparison (putting aside nan handling). A hypothetical relu instruction could probably get away with much less po

Citadels’s market-making arm, Citadel Securities, IS extremely competitive in on-exchange trading. They don’t just do wholesale market making (I.e. service for a price), they provide liquidity on-exchange as well (much more competitive&#x2F

I’m pretty sure Citadel securities makes more money from their non-wholesale businesses (I.e. on-exchange trading) instead of their retail pfof business. Either way, they are very successful in the competitive hft/trading arm as well a

One answer here is that with dated rates products (I.e. all futures and options, not to mention spot ficc) is * pricing is well understood * shares similar risks across all products If you add an ES perp, that might be a fine instrument in

Index futures are among the most liquid and highly traded instruments and have no natural expiries, a perpetual might make sense. There is a direct correspondence between the rates component of the index futures and all other naturally expi

Agree with the above, will add that proper fuzzing is worth it quite often also. If your ecosystem has tooling for structured fuzzing (or it's easy for you to fuzz from a raw series of bytes), fuzzers are relatively effort to add and v

You'd be surprised how common the view "Performance doesn't matter now we'll just fix the hotspot later" is

by vgatherps 3y ago
To be fair, performance is usually part of the “does it work in real life” question, it’s just that doing sensible things is probably good enough. The crud app at your startup probably doesn’t need to worry about cutting optimizing every la

There’s some discussion here about whether Luna/UST was a crime given that everybody know how it worked, is it a crime to be dumb / massively fail at business, etc. There’s a myriad of actual fraud allegations against Do Kwon, inc

The prioritization of refactoring is strongly context dependent. A small startup with a fast moving product trying to acquire and retain customers cares much more about serving said customer right now than an established business who has

It seems like a pretty standard (and simplified for HN) classification of employees who are and aren’t able to prioritize well. Employees who can prioritize well will naturally be given more independence to make choices than those who don’t

It's the opposite, FTX was selling customer BTC to prop up their own coins. This is also a clear example of how difficult it is to prop up a coin, even relatively illiquid ones like the FTX coins. FTX could sort of prop up their own co
