Show HN: An AI agent that trades inside limits you set, starting on paper
It screens opportunities, reads the supporting and conflicting evidence, checks portfolio fit, calculates a risk budget, previews an order, follows the account's approval policy, monitors the resulting position, and records what happened.FST does not remove market risk and does not guarantee a profitable outcome. Its purpose is to make the decision and execution process more consistent, observable, and accountable while keeping hard controls outside the language model.The product is one connected system across QS Research, FST, and QS Brokerage. Trading involves risk, paper results do not represent future live results, and no AI trading agent can guarantee a profitable outcome.Can I test FST without a live brokerage account?Yes.
