Hello

Starting a journal. “Blog” feels a bit dated but it’s the same thing. You can find it at blog.ehrlich.dev or journal.ehrlich.dev - same place.

I use LLMs to help write this. If something reads like an AI wrote it, that’s a failure. Let me know: [email protected].

First up: people sometimes ask about options trading when it comes up that I do it for fun. The answer takes a while, so I wrote it down. Five parts, starting with what a derivative is.
