In Patrick’s words, above the fold:
Some years ago, I built a trading simulation for a startup I was running, Starfighter. It was, at the time, by far the most impressive technical artifact I’d ever made, including a scratch-built fake stock exchange. I recently ran into Rick Heicklen, who has a business teaching trading, and said we should swap notes on comparative pedagogical game design.
Trading doesn’t have a vast body of useful information targeted at people of various skill levels. There is a vast amount of fanfic. Actual practitioners work at a relatively small number of firms and are extremely disincentivized from explaining how the world really works to outsiders. Ricki and I talk about some of the lessons people learn early in their trading careers, how those correspond to market microstructure which impacts everything tied to the financial markets, and the security mindset. There are also some (perhaps surprisingly) portable lessons from trading to many other complex systems.
The link has 1.7hr of audio and 23k words of transcript. Patrick is on Twitter, writes his newsletter, and has written on the EA Forum; Ricki is iiuc Lightcone staff, and writes on LessWrong, Twitter, and her own blog.
For longtime readers of patio11 or even just his new blog, I think most of this will not be new, except for the discussion of Stockfighter: patio11 discusses how he generated realistic stock price histories for the simulated stock market (he copied real histories—I would’ve done something similar, but phrased it as a ‘block bootstrap’ or something), and also the final level of Stockfighter, which turns out to be ‘detect the inside trader’ and quizzes Ricki on how to do it both with and without the intended approach of ‘hacking’ the simulated stock market to get IDs for traders’ trades & find the trader with excessive returns.
(If you are interested in Jane-Street-esque discussions of trading & adverse selection and this is too entry-level, possibly LeBron’s 2019 The Laws of Trading might be a better use of reading time.)
There’s also Byrne Hobart’s article Understanding Jane Street (5.5k words), although pitched at an even lower level maybe. He recommends The Laws of Trading as further reading, alongside:
