API Throughput Limits
API Throughput Limits refer to the maximum number of requests or data packets a trading platform or exchange allows a user to send within a specific timeframe, typically measured in requests per second. In the context of cryptocurrency and derivatives trading, these limits are essential for maintaining system stability and preventing infrastructure overload.
Exchanges enforce these thresholds to ensure that high-frequency trading bots or algorithmic strategies do not overwhelm the matching engine, which could lead to latency issues or system crashes. When a trader exceeds these limits, the API typically returns an error code, effectively throttling or blocking further requests until the rate resets.
Understanding these limits is critical for developers building automated trading systems, as efficient code must be designed to respect these constraints to avoid service disruptions. These limits are often tiered, where higher-volume or premium institutional accounts may be granted higher throughput thresholds than retail users.
Effective management of these limits is a core component of market microstructure, as it directly influences how quickly orders can be placed, canceled, or modified in response to market volatility.
