  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.
