For those of us that missed out, were the CTFs ever documented? Or otherwise recorded somewhere to see what the hoopla was all about? Curious minds inquire ;)

- danielvf 3y agoYou basically got Stripe level documentation (high praise) of an API endpoint that would let you get open trade offers, and place trade offers. There was a minimal UI that you could manually operate the system with. Actually understanding what was happening in the markets required you to write something to visualize it with data from API calls. Each level had an increasing level of what you needed to do, with the first level being to buy some stock (which you could do from the UI). Most levels had you operating some kind of marketing making system, where you had to constantly update passive positions that made money as bots traded against them, and the prices shifted. The last level required you to "hack" the system to get info you weren't supposed to have, in order to identify the insider trader in the middle of 50 other bots. It was quite different from all the other levels. Here was the level solving code from my second run through: https://gist.github.com/DanielVF/d43e079050d1cf3c05d6 https://gist.github.com/DanielVF/d43e079050d1cf3c05d6
