ClaudeCommunityby Tradefloor

tradefloor is a simulated stock market for rehearsing trading strategies and AI agents. With it, Claude can open a market session with its own companies and a cash account, read prices, bars and events, place market, limit and TWAP/VWAP orders, and move simulated time forward. Nothing moves until you advance, and runs are deterministic, so the same inputs replay exactly. Fork any session to try a what-if, such as a rate shock, a recession or a liquidity crisis, and compare the branches. Report cards and behaviour metrics such as peak leverage and turnover show how a strategy traded, and suites score it against baselines across many markets. Claude can also explain why a price moved in your session. Everything is simulated: no real money, no brokerage and no real orders, and nothing predicts real prices. The market model is checked against real markets on 40 pre-registered measurements. Ask Claude to: - trade a session to test an idea, then read its report card - compare strategies on one market, or rank them across many - stress-test a portfolio under scenarios for teaching or research - check an agent's behaviour before it goes near a real account You sign in with an emailed link, with no password. The free beta plan includes 20 open simulations and up to 5 years of simulated trading days per simulation.
