CTO of an HFT firm here. My opinion: repo (and probably author’s comments) are LLM-generated. That said, many questions and techniques touched upon are real. So even though I certainly would not use any of these verbatim (as I wouldn’t do with any other LLM code), as a list of pointers for someone relatively new to the field this is actually pretty useful.
Saves you a “generate low-latency trading system” prompt anyway.
It does not. If this was the case, round trip wire to wire latency below 1.0-1.2 microseconds in software would’ve been impossible. But it clearly is possible - see benchmarks by Solarflare, Exablaze, and others.
They were most definitely IFR. Not because of the weather but because IFR is required above certain altitude 18,000 ft in the U.S. and typically lower in Europe (depends on a country). Jets including small private jets are almost always on IFR. Airliners with passengers - always.
Russian propaganda does not say that. Putin himself said on multiple occasions that any theories of staging moon landings are silly. Don’t have a reference at the moment but I have seen several Putin’s interviews to that effect.
Russian propaganda is alive and well on many topics but denying American moon landings is not one of them.
One does not need a lot of bandwidth to trade successfully. In fact, a limited number of signals agreed upon ahead of time is enough. E.g. signal “A” could mean “buy 10 contracts”, signal “B” - “sell 100 contracts”, etc. And you can of course wrap 256 such signals into one byte. So transmitting a single byte at an opportune time let’s you control your trading on the other continent in a quite precise fashion. If you make such transmission, say, 10 times per day your bandwidth utilization is technically 10 bytes per day or about 0.001 bps - yet you can make a ton of money.
Respect and courtesy are nice but I think the reason this style is so effective is different. It makes the counterparty believe that you are collecting the paper trail to file a lawsuit. And behaving like you are preparing to file a lawsuit is much more effective than just claiming you will be filing a lawsuits.
I imagine that when presented with a choice of $88 payment or having to deal with a lawsuit, 100% of decision-makers will chose the former. And it’s not about the lawsuit outcome. Even if some complete garbage is filed which has no chance of success, the burden it creates on the business is clearly much higher than $88.
And I know a business owner who is shopping for a new house after getting a PPP “loan”. Sure, PPP money is supposed to be used for payroll. No problem, one can indeed use PPP money for payroll 100%. But then use the business revenue, 90% of which would normally be used for payroll, to take out a nice bonus and buy a house.
So, what if a business was successful, not impacted by covid, and wasn’t planning to lay off any employees anyway? Say, technology consulting company with 100 employees. Took out a PPP “loan”, which will be promptly forgiven since they keep the staff, who gets to keep the money? Something tells me 100% goes to business owner and 0% to employees.
I think there are quite a few companies like this. Hence “money goes to those who least need it”.
Comments about storage costs are nice theory but don’t tell me those storage costs went up 50 dollars a barrel to cause CLK0 to go from +10 to -40 within something like 30 minutes. It was all forced liquidation by brokers like IB and people absolutely bamboozled by negative prices puking their positions. Nothing to do with costs for actual storage.
Strategic Petroleum Reserve uses salt caverns to store crude oil and has the capacity of 797 million barrels [1], which is equivalent to roughly 500-700 larger tankers. Both construction cost and carry cost per barrel are, of course, much lower vs. tankers.
Would creating, say, online marketplace to help people lose desired amount of money with certainty - for example, via some sort of specially crafted financial instrument - violate any applicable rules & regs? Idea for the next YC batch?
