None of the blockchains use 2PC. The blocks may get discarded after a while. Sort of eventual consistency

Thats a general critique for published trading algorithms I've ever seen millions of times, but if you kindly take a close look at it, it accepts which stock to trade as parameter, and I'm running it with some other stock than the default parameter.


As we build our API trading brokerage, we wanted to show something like HFT algo can be built quickly. Chatting with an ex-HFT guy, I quickly built this and put it in GitHub, so anyone can run it. 261 lines of python. Check out https://github.com/alpacahq/example-hftish for the code and a bit of explanation on medium https://medium.com/automation-generation/hft-like-trading-al...

When did software devs lack the power to write trading tools? The issue is that the traders had the knowledge and wrote their ideas into a spreadsheet which was not only maintainable for them but easily extensible. I cannot overstate that second part. They become spreadsheet behemoths because it's trivial to make them do that one extra thing (at least for the first fifty or so features).

Probably when the IT peeps in finance believe that the problem with spreadsheets is their speed. As the fundamental problem of spreadsheets in finance has absolutely nothing to do with their speed, this may take a while.
