Paper trading lets you practise trading with simulated money. Size also uses a virtual balance during its games, then adds a defined game format with stages, scoring, and eliminations. The choice depends on whether you want an open-ended trading simulator or a game built around trading decisions. ## What changes? | | Size | Conventional paper trading | | --------------- | ---------------------------------------------------------- | ------------------------------------------------------------- | | Main activity | Play a trading game | Practise placing and managing trades | | Trading balance | Virtual | Simulated | | Structure | Timed stages and elimination rules | Typically an ongoing practice account; provider features vary | | Performance | Game score and rank, alongside P\&L | Usually account performance and trade history | | Payment | Free practice, or an entry for a paid prize game | Access and subscription terms vary by provider | | Rewards | Practice earns XP; paid games can award the selected prize | Ordinary simulated gains are not withdrawable cash | ## Choose paper trading when… You want to explore order types, record practice trades, or test how you manage positions in a simulator. Choose a tool that reflects the instruments and controls you want to practise. ## Choose Size when… You want a defined trading game: watch your position, follow the stage objective, and see where you finish. Start free to understand the format. A paid game adds an entry you can lose and a displayed prize for a qualifying win. ## Does a good result prove I can trade profitably? No. A game result or simulated trading record does not establish future live-trading performance. Size score, virtual P\&L, XP, and cash prizes are separate measures. ## Start free [Play your first Size game](https://www.size.club/docs/start/first-game), or read [Game rules](https://www.size.club/docs/gameplay/game-rules). ### Sources Reviewed 22 October 2026.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://www.size.club/docs/compare/paper-trading.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
