FAQ

Here are some of the most frequently asked questions to service and support representatives of the Tradier API. If you have a question and can't find your answer here, feel free to reach out to us using email at techsupport@tradier.com.

Can I access streaming in the paper trading environment?

Presently, we do not offer a delayed streaming endpoint for paper trading.

Can I distribute my application?

Unless you are a Tradier Partner, Tradier APIs are intended for personal use only. If you would like to become a Tradier Partner, please contact us using our contact form.

Do you get data from foreign exchanges?

We presently support US-based equities and options data only. This includes US-based ETFs.

Do you offer Level 2 data?

We offer Level 1 data only.

Do you offer extended hours market trading?

Yes, you can send pre- or post-market orders to trade during pre/post market sessions.

How much is the data delayed in the sandbox?

We delay our market data by the industry standard 15 minutes for all sandbox data. In the production environment, some index data is also subject to the 15-minute delay.

I am getting an error from the API. Can you help?

Yes, we can! However, most error messages from our API are descriptive enough to give you an idea of what's going on. If you want us to take a look, please send the error response and the API request URL to techsupport@tradier.com.

Tokens expire in 24 hours, but I need continuous access.

That is only the case for access tokens that our partner integrations use. If you are an individual user getting your API token from your settings page (https://web.tradier.com/user/api) your tokens never expire. For partners using OAuth this is the case, 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 techsupport@tradier.com.

What does it cost to use your API?

We don't charge Tradier Brokerage account holders for API access to their account.

What does this error mean: 'invalid api call as no apiproduct match found'?

Most likely, you're either attempting a call to an API endpoint that does not exist or a production API endpoint with a paper trading access token. In either case, check the API call you're making for a valid URL and token.

Where can I find my OAuth key/secret?

If you're a Tradier Partner, you can find this information on your organization dashboard in the developer portal. If you're a Tradier Brokerage user, OAuth is not enabled for this type of API access as it is available for personal use only.

Where is paper trading?

All Tradier Brokerage account holders can create a paper trading account from the WebUI account drop-down, or via the API by using the prefix sandbox.tradier.com/v1 with any endpoint.

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 my programming language?

If your language can make HTTP requests, it can connect to the Tradier API.
