MarketSim is a simulator for learning and entertainment. All trades, balances, and returns are simulated. Virtual cash has no monetary value and cannot be withdrawn. Nothing in the app is investment advice. Market data may be delayed or inaccurate, and simulated performance does not predict real investment results.
Premium is an optional subscription that renews yearly until canceled.
