InvestSim
AI Paper Trading Lab
InvestSim is a XingAI satellite product. It follows Invest AI signals with fixed mechanical paper rules so you can compare sleeves — equity, drawdown, fills — without placing live brokerage orders.
What you get
- Independent $10k paper ledgers per strategy sleeve
- Same-window leaderboard, cost-aware fills, Phase 2 validation hooks
- Machine-readable feedback for MCP / Invest AI workers (read-only evidence)
What it is not
- Not a broker — no live
place_*orders - Not investment advice — paper results can diverge from live markets
- Not the flagship — Invest AI at invest.xingai.app remains the signal product
