Key takeaways
- A bridge connects your MT5 trade server to liquidity providers, usually over FIX.
- Multi-LP set-ups add price aggregation and failover.
- Test fills, rejections, slippage and disconnections before go-live.
What a bridge does
A bridge receives orders from MetaTrader, sends them to one or more liquidity providers, and returns fills and prices. It also applies routing rules, markups and risk logic. Leading solutions include OneZero, PrimeXM, Gold-i and Centroid.
FIX connectivity
Most liquidity providers connect over the FIX protocol. Each connection has sessions for prices and orders, credentials and network requirements such as IP whitelisting or cross-connects.
Multiple liquidity providers
- Aggregation: build the best bid and offer from several LPs.
- Failover: keep pricing if one LP disconnects.
- Routing: send flow to different LPs by symbol, size or group.
Pre-launch tests
- Market and pending order fills per symbol.
- Rejections and requotes handled correctly.
- Behaviour when an LP disconnects.
- Spreads and markups per group.
- Latency between trade server, bridge and LP.
