How to choose a liquidity bridge provider
A liquidity bridge provider supplies and usually hosts the software that connects your liquidity providers to MT4, MT5 and your other platforms. Choosing one comes down to eight checks: the platforms it covers, how LPs connect, how much pricing control you get, aggregation, the pricing model, hosting, monitoring and the cost of growing.
Eight checks before you choose
Most switching stories start with one of these being missed in the first conversation.
- 01
Platforms you run
MT4, MT5, a web terminal, a mobile app, FIX clients. A provider that covers only one will leave you building the rest.
- 02
How LPs connect
FIX 4.4 or TCP, how many LP sessions are included, whether it works with Centroid, and how a silent feed is noticed.
- 03
Pricing control
Markups per platform or client group, spread limits, fixed spreads, and a guard against crossed quotes.
- 04
Aggregation and failover
Best price, a single LP, or priority with automatic failover, chosen per symbol.
- 05
Pricing model
A flat monthly fee, a fee per million traded, or both. Volume fees grow with your flow; flat fees do not.
- 06
Hosting and IP
Who runs the server, whether it is shared, and whether you get a fixed IP your LPs can allow-list.
- 07
Monitoring and support
Alerts for stale prices and dropped sessions, where they go, and who answers when something breaks.
- 08
Room to grow
What another LP, another platform or another brand costs, and whether it needs a new contract.
How bridge providers charge
The model matters as much as the number: the same provider can be cheap at one volume and expensive at another.
- Flat monthlyHow it works:A fixed fee per month for a set capacityGood:Predictable; costs do not grow with volumeWatch for:Can cost more than a volume fee at very low volume
- Volume basedHow it works:A fee per million USD tradedGood:Cheap while volume is smallWatch for:Grows with every lot your clients trade
- HybridHow it works:A base fee plus a volume fee above a thresholdGood:A middle groundWatch for:Two numbers to model, and the threshold matters
- Licence and setupHow it works:A one-off licence or setup fee, often with maintenanceGood:Lower running cost laterWatch for:Large upfront cost, and you may run the servers yourself
Model your own volume before you compare quotes. The liquidity bridge cost guide has a calculator for flat and volume based pricing.
Building a shortlist
Three steps that make vendors easy to compare.
Write your setup down
Your LPs and how they connect, your platforms, your symbols, your monthly volume and how fast you expect to grow.
Ask everyone the same questions
Use one checklist for every vendor, so answers line up side by side instead of in different sales decks.
See it on your own symbols
A demo on your own LP feed and symbols shows mapping, spreads and monitoring as they will be, not as a slide.
In XiroLink
XiroLink as your bridge provider
XiroLink is a hosted liquidity bridge: LPs over FIX 4.4 or TCP, MT4 and MT5 datafeeds, WebSocket and FIX for everything else, markups per platform, best price or priority failover per symbol, and monitoring with alerts. Each broker runs on its own server with a fixed IP, at a flat monthly price from $799 with no volume fees.

Bridge provider questions
What is a liquidity bridge provider?
A company that supplies the software, and usually the hosting, that connects a broker’s liquidity providers to its trading platforms. The bridge provider is not the liquidity provider: it connects to the LPs you choose.
What is the best MT4/MT5 bridge provider?
The one that covers the platforms you run, connects to your LPs over FIX or TCP, gives you control of spreads per platform, and prices in a way that suits your volume. Put the same questions to every vendor on your shortlist and compare the answers side by side.
How much does an MT4/MT5 bridge cost to set up?
Setup ranges from free to several thousand dollars, and running costs are a monthly fee, a volume fee or both. XiroLink costs $799, $1,499 or $2,499 a month with no volume fees; setup and onboarding is $500 once, free on annual plans and Enterprise.
What is the best way to connect to several FX liquidity providers without building in-house infrastructure?
Use a hosted liquidity bridge. It keeps a session to each LP, aggregates their prices per symbol, applies your markups and delivers to MT4, MT5, web and FIX clients, while the provider runs the servers, the fixed IP and the monitoring for you.
Is a bridge provider the same as a liquidity provider?
No. The liquidity provider quotes the prices and fills the orders. The bridge provider connects those prices to your platforms, applies your pricing and keeps the connections running.
