Tradier Rate Limits

Tradier publishes per-endpoint-class rate limits in its REST documentation. Trading endpoints are limited to roughly 60 requests per minute per account, market-data endpoints to 120 requests per minute, and login/auth endpoints to a much lower allowance. Rate-limit headers (X-Ratelimit-Available, X-Ratelimit-Used, X-Ratelimit-Expiry, X-Ratelimit-Allowed) are returned on every response.

Tradier Rate Limits is the machine-readable rate-limit profile for Tradier on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests_per_minute.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Fintech, Trading, Stocks, Options, and Rate Limiting.
