BOSS

Paper trading

Simulated positions opened from a strategy page at live execution prices, followed here with real market data until you close them or they expire. Nothing is traded.

Your positions are saved only in this browser (local storage) and never reach BOSS's servers: clearing this site's data deletes them, so export a copy to keep one. Fees are estimates, a real fill can be worse than the top of the book, and expiries settle at the venue's official delivery price once BOSS has recorded it, estimated until then.
