Not OP but here's why I think it's a great choice: it's the kind of book you could read many times and still not understand every nuance. There's a joke in the literary world that nobody has ever read it in full. It&#x27

Excellent question! The TL;DR is that substitutability and the ability to manage risk (e.g. execute hedges or constrain factor exposure atomically) can be great for inducing liquidity in the absence of large volume and high turnover. On sub

The company is US based but we're entirely open to remote work especially for engineering, and already have a handful of fully remote staff.

The funny thing about the emergence of HFT is that if you truly only have a hundred or so shares to buy/sell it's quite cheap and easy to do that now. Atomicity and substitutability isn't as important if there's plenty o

We're still going through integration and test/simulated trading with initial set of users so nothing public yet. But once we cut over to real cash/equities our volume data will all be published through FINRA's site[0].

No worries, happy to concretize this: the really easy example would be shoes. How much would you pay for just a right shoe or just a left shoe? A lot less than the pair, since you might not be able to find the other shoe in the right size,

An ATS is like an exchange, so we match buyers and sellers. And you guessed correctly that the initial users are institutional investors - or more directly their brokers. So initially we'll have institutions creating and sending in &qu

Couldn't agree more on the mechanism design front. There are so many dimensions to the problem - especially for US equities - that the design becomes quite nuanced and tradeoffs have to be made somewhere or other. The duration aspect o

The hedging scenario you describe is one of the hallmarks of combinatorial auctions[0], which let participants enter bids on packages. (Disclaimer, I'm a founder at OneChronos which is applying these auctions to US equities.) So a mark

There's a protocol being worked on called STIR/SHAKEN to address robocalls [0]. It's more like website / browser certificate PKI than spam filtering. Some of the major US telcos are working toward implementation already.

Does it matter if a robot can build a car? People can build cars. Of course it matters. A bot can scale to appear as millions of people. So whoever wields the most compelling bots gets a massive force-multiplier for their opinions and objec
