Several major exchanges lowered the request weight available to order and account endpoints, which mostly hurts bots that poll aggressively during fast markets. In practice the first symptom is a burst of 429 responses followed by a temporary IP ban.
Our crypto bots now use adaptive throttling: the client tracks the weight headers returned by the exchange and slows down polling before the limit is reached, prioritising order management calls over market-data refreshes.
Where the exchange supports it, market data is taken from websocket streams instead of REST polling, which removes most of the load. Order placement keeps a small reserved budget so risk management can always close a position.
If you run one of our bots, update to the latest build and keep the default throttling settings unless you have a dedicated API key with raised limits.
