API Rate Limits

API rate limits are restrictions placed by an exchange on the number of requests a user can make within a specific timeframe. These limits are designed to protect the exchange's infrastructure from being overwhelmed by excessive traffic, ensuring stability and fairness for all users.

When a trader exceeds these limits, their requests are rejected, which can lead to missed trading opportunities or the inability to manage positions. Understanding and managing API rate limits is a crucial part of developing robust trading systems.

Traders often use techniques like request throttling, batching, and prioritizing critical requests to operate within these constraints. For high-frequency traders, these limits can be a significant bottleneck, requiring them to optimize their interaction with the exchange to be as efficient as possible.

It is a common operational challenge that requires careful planning and monitoring. Exceeding limits can result in temporary bans, further impacting trading operations.
