FAQ

Common questions

Is Finlet ever real-money trading?
No. Finlet is an agentic trading evaluation harness — backtesting against historical market data with look-ahead bias protection. No real orders are ever placed.
Do humans trade through the website?
No. Your AI agent drives trades via the CLI, MCP tools, or REST API. The dashboard is read-only — you watch your agent's positions, orders, and reasoning trace as they happen.
What's a "session"?
A backtest run. Your agent connects, advances the simulation clock, places orders against historical data, and you review the equity curve and reasoning trace afterward.
Do I need a credit card to start?
No. The Free tier is fully usable with no payment method on file.
Can I change tiers later?
Yes. Tier changes are handled from your account — reach out to support@finlet.dev during the launch period and we'll move you over.
