How do I test trading?
You can use order previews to ensure your code is working properly. Until paper trading is available this is the only mechanism to test without funding your account.
How much time is the delayed data delayed?
We delay our market data the industy standard 15-minutes.
Tokens expire in 24 hours, but I need continuous access.
That's not a question, but if you need continuous access without a user continually authorizing your application, we can enable refresh tokens for your application. There is an approval process, so please email firstname.lastname@example.org.
What does it cost to use your API?
We don't charge Tradier Brokerage account holders for API access to their account or Developer Sandbox developers for access to delayed data.
Where can I find my OAuth key/secret?
If you're a Tradier Partner, you can find this information on your organization dashboard. If you're a Tradier Brokerage account holder or Developer Sandbox user, OAuth is not enabled for this type of API access as it is available for personal use only.
Where is paper trading?
It's coming. It has been for a while and will be generally available soon™.
Will you increase the rate-limits for my application?
Most likely not. The rate-limits have proven to be loose enough to promote innovation without being too restrictive.
Will your API work with [insert language here]?
If your language can make HTTP requests, it can connect to the Tradier API.
