      About this replica

      A browser port of the research framework alejandroll10/llm_trading_sim, where LLMs act as trading agents in a simulated market. This replica runs fully client-side in vanilla JavaScript — no server, no API keys.

      Real LLM calls aren't possible from a static page, so each agent is a deterministic proxy that mimics a distinct personality: value-oriented analysts, momentum speculators, optimists, pessimists, short sellers, leverage traders and market makers. The matching engine, order book, dividends, leverage, short interest and round lifecycle follow the original design.
