Show HN: Multi-Agent Market Simulator for Studying Emergent Trading Dynamics

6 parkercarrus 2 8/26/2025, 1:42:55 PM aitradingsim.com ↗

I built this simulator to study how simple trading agents interacting with an order book can create emergent patterns—volatility, clustering, even chaos—without any external shocks. It’s meant as both a research toy and teaching tool. You can run different strategies, adjust configs, and watch dynamics evolve. Curious to hear feedback from the HN crowd on features/dynamics you’d like to see added.

Would it be possible to plug in real-world market data or news to see how the agents react?

Right now the simulator is intentionally “closed-world” — no external data feeds, just agents interacting through the order book. The idea is to strip away news/fundamentals and see what dynamics emerge purely from agent interaction. That’s where things like volatility clustering and liquidity droughts show up without being hard-coded.
