For experimental purposes only. Not financial advice, and I fully expect it could (and most likely will) go to shit. The point is the setup, not the money. I wired up an autonomous trading loop where the models check each other instead of just agreeing: Claude is the “CEO” — runs morning research and places the trades. Codex (GPT-5.5) is the red-team — every trade idea gets handed to it to try and kill before anything is placed. Two different model families catching each other’s blind spots. Three scheduled agents: a morning research+trade run, a pre-close risk check that enforces stop-losses, and a weekly strategy review. Cheap model for the daily grind, premium model only on exceptions (to keep token costs sane). The part I’m most into: a local LLM (Gemma 4 running in LM Studio on my laptop) acts as an always-on news watchdog in near real time. It filters the market-news firehose and only escalates the genuinely material stuff up to the cloud agents and pings my phone. Free, private, and runs all day. Day 1, it actually talked itself out of a hyped trade: Codex noticed the next session was a market holiday and flagged the whole thing as a “sell-the-news” trap. The discipline surprised me more than anything. Aggressive goal, probably unrealistic — but watching the agents reason, disagree, and stay disciplined is extremely interesting. It could be fun. Will most likely go to shit. But it’ll be an entertaining couple of hundred bucks. Also, did deep research on tax and capital gain implications and feel comfortable with how Robinhood will handle the 1099-B form and tracking trades. Before people start shitting all over this. Again, it’s only for fun and an experiment. submitted by /u/the_pezcorekid
