Liquidity bridge & FIX API development
Prices in, orders out —
on your terms.
A liquidity bridge decides what prices your clients see and where their orders go. We build bridges and FIX API gateways that connect MetaTrader 5, cTrader, or your own trade server to your liquidity providers — with aggregation, markups, smart order routing, and the A-book, B-book, and hybrid rules your dealing desk runs on.
FIX is the standard language of electronic trading, maintained by the FIX Trading Community. We deploy close to your liquidity — for FX, that usually means Equinix LD4 in London, home to the world's largest multi-asset electronic trading ecosystem.
In short
- Nima Dorostkar's team builds liquidity bridges and FIX 4.4 gateways connecting MetaTrader 5, cTrader, or a proprietary trade server to liquidity providers.
- Bridges include price aggregation, markups, smart order routing, A-book/B-book/hybrid rules, and feed filtering.
- Every quote decision and execution report is stored, so any fill can be reconstructed.
What we build
Liquidity bridge development:
what's included.
FIX connectivity
FIX 4.4 sessions to liquidity providers and prime brokers, with session management, sequence recovery, and drop copy.
Aggregation & markups
Best bid and offer across LPs, spread markups per client group, and synthetic instruments built from underlying quotes.
Smart order routing
Route by size, symbol, or client risk score, with partial fills, rejections, and last-look responses handled explicitly.
A-book, B-book & hybrid
A rules engine for routing decisions, exposure limits per symbol, and automated hedging when limits are crossed.
Price feed & filtering
Spike and stale-quote filters, feed failover between LPs, and tick storage in TimescaleDB for replay and audits.
Execution monitoring
Latency, fill ratios, rejections, and slippage per LP — reported daily and alerted in real time.
How we build it
Engineered for
real money, from day one.
- 01Correctness before speed
Every order state transition is explicit and logged, so no order is ever lost between your platform and an LP.
- 02Low latency where it matters
Go services on the hot path, hosted near your LPs, and measured under load before launch.
- 03Failover by default
Feed and session failover between LPs, with safe fallbacks when a provider goes quiet.
- 04Full audit trail
Every quote decision and execution report is stored, so any fill can be reconstructed for a client or a regulator.

Questions
Liquidity bridge development FAQ
What does a liquidity bridge do for a broker?
A liquidity bridge connects a broker's trading platform to its liquidity providers. It streams prices from the providers to the platform — often aggregated and with markups applied — and sends client orders out for execution, returning fills, rejections, and execution reports to the platform.
Can you connect MT5 to several liquidity providers at once?
Yes. The bridge connects MetaTrader 5 through the Gateway API and holds FIX sessions with each provider, aggregating their prices and routing each order to the provider your rules choose.
How does A-book and B-book routing work in a custom bridge?
Each order is checked against routing rules — by client group, symbol, size, or risk score. A-book orders are sent to a liquidity provider; B-book orders are kept in-house within exposure limits; hybrid rules can hedge part of the flow automatically when exposure crosses a threshold.
Should a broker build or buy a liquidity bridge?
Buying a bridge is faster to start with. Building one makes sense when you need routing logic a vendor can't configure, run several trading platforms, want to avoid per-volume fees, or need full control of execution data for compliance.
