Bridge vs gateway: choose execution connectivity by workflow.
Bridge and gateway terminology is often used loosely. The important distinction is how orders, market data, routing logic, risk workflows and liquidity connections are integrated into the broker operating stack.
Bridge approach
A bridge commonly provides an external routing and integration layer between the trading platform and liquidity or execution systems, often with configurable routing logic.
Gateway approach
A gateway can provide a tighter or more direct connection model depending on the platform and liquidity technology involved, with different operational characteristics.
What to compare
Evaluate routing flexibility, latency, failover, monitoring, symbol mapping, reporting, risk workflow compatibility and support rather than choosing by label alone.
