Gateway Redundancy

Gateway redundancy involves maintaining multiple, geographically or logically distinct paths to an exchange's API to ensure uninterrupted trading. By routing orders through different infrastructure points, traders can bypass local ISP issues, regional network congestion, or specific server-side failures at the exchange.

If one gateway experiences increased latency or connection drops, the system automatically switches to a backup, maintaining the continuity of the trading strategy. This architecture is essential for professional firms managing high-leverage positions where downtime can lead to catastrophic margin calls.

It reflects a defense-in-depth approach to market microstructure, acknowledging that network infrastructure is a point of failure. Proper redundancy management includes load balancing and health checks to ensure that the backup path is as performant as the primary.

This strategy minimizes the impact of systems risk and contagion by isolating the trading engine from infrastructure volatility.
