what makes it different

built for learning, not speculation.

most simulators gamify trading. the lab is designed to build real understanding of portfolio dynamics, risk, and macro forces — without the bravado.

every ticker in the lab is drawn from real historical price data. lse-listed funds, us indices, gilt benchmarks. no synthetic numbers, no made-up returns. the context is real; the stakes are not.
