The service
Papertrade is a free simulator for practising stock trading with virtual money. You can trade simulated positions on live or historical market data, apply simulated broker fees, and let AI apps trade your simulators through MCP or our API. Nothing you do on Papertrade buys or sells real securities, and no real money is ever held, deposited or paid out.
Not financial advice
Everything on Papertrade is for education and testing only. We are not a broker, exchange, investment adviser or financial institution, and nothing on the service is investment, tax or legal advice. Simulated results don't predict real results. See our Risk Disclaimer.
Who can use it
You must be at least 18 years old and able to agree to these terms. If you use Papertrade for an organisation, you confirm you can bind it to these terms.
Your account
- Give a real email address and keep your password safe. You're responsible for activity on your account.
- API keys and AI app connections act as you. Keep keys secret, and revoke any you no longer use or think are exposed.
- You're responsible for what the AI apps you connect do with your account.
- Tell us at once if you think someone else is using your account.
Acceptable use
Don't:
- break the law or anyone's rights while using the service;
- scrape, bulk-download, resell or redistribute market data or other content from the service;
- overload, disrupt or try to get around limits or security, including through automated traffic beyond normal use of the MCP and API;
- access other people's accounts or data, or probe the service for vulnerabilities without permission;
- reverse engineer the service, except where the law allows;
- present simulated results as real trading results, or use the service to mislead others about investments.
Market data and third parties
Prices come from third-party providers. They may be delayed (some exchanges by 15–20 minutes), incomplete or wrong, and their terms allow personal, non-commercial use. Broker fees, taxes, trading hours and holidays are simulated from public information and may be out of date. Broker, exchange and company names and logos belong to their owners; we use them only to identify what's being simulated, and no endorsement or affiliation is implied. AI apps you connect are governed by their own terms.
Our content
We own the Papertrade software, design and content. We give you a personal, revocable, non-transferable licence to use the service under these terms. You keep any rights you have in what you put in (for example simulator names), and give us permission to store and process it to run the service.
Free service, changes and ending
Papertrade is free today. We may change, add or remove features, introduce paid plans (we'll tell you first and won't charge without your agreement), or stop the service. You can stop using it at any time and ask us to delete your account. We may suspend or close accounts that break these terms or put the service or others at risk.
Disclaimers
The service is provided "as is" and "as available", without warranties of any kind, including accuracy, availability, fitness for a particular purpose and non-infringement, to the fullest extent the law allows.
Limitation of liability
To the fullest extent the law allows, we won't be liable for indirect, incidental, special, consequential or punitive damages, or for any loss of profits, money or data, including losses from trading decisions you or your AI make outside Papertrade. Our total liability for any claim is limited to US$100. Some places don't allow these limits, so they may not all apply to you.
Indemnity
You agree to cover our reasonable costs from claims caused by your misuse of the service or breach of these terms, including by AI apps acting for you.
Law and disputes
These terms are governed by the laws of the United States and the state in which the operator resides, without regard to conflict-of-law rules. Nothing here removes rights you have under the consumer protection laws of the country where you live. Please email contact@papertrade.world first so we can try to resolve any problem informally.
Changes to these terms
We may update these terms. We'll revise the date at the top and, for significant changes, give notice on the site or by email. Using the service after changes take effect means you accept them.
