oneZero Hub Integration for MT4 and MT5 Brokers

What is oneZero Hub?

oneZero Hub is a Software-as-a-Service pricing and risk management system that sits between a broker's trading platform and its liquidity providers (LPs). It builds prices from several LP streams, applies spreads and markups, decides whether client orders are hedged externally or kept in-house, and records quote and trade data for analysis.

oneZero describes the product in its own words as follows:

"Our Hubs are robust Software-as-a-Service price and risk management systems. Designed for scalability, security and reliability, our technology enables the seamless management and routing of tens of millions of trades daily by hundreds of clients around the globe."— oneZero, Hub Technology (accessed October 2026)

Three facts from oneZero's own site matter most for an integration plan:

• It is hosted, not installed on your server. oneZero states that "each Hub is a dedicated, hosted instance" and offers co-location options in the NY4, LD4 and TY3 data centres (Hub Technology page, accessed 8 October 2026).
• It works with MetaTrader 4 and 5. The Retail Hub page says brokers can "establish connections to your customers via front-end trading platforms including MetaTrader 4/5 for the receipt and delivery of quotes and trades" (Retail Brokers page, accessed 8 October 2026).
• oneZero is a technology provider, not a liquidity provider. Its site footer states that oneZero "is not a broker, and does not act as a trading principal". The homepage adds that the company is "liquidity neutral and independent".

For scale, oneZero's homepage states that its technology handles "$250B+ ADV, 14 million transactions and 400 billion quotes per day", and its company page (accessed 8 October 2026) states it was founded in 2009 and serves 250+ customers. On 6 October 2026 oneZero announced that it had been named World's Best FX Trading Solution in the Euromoney FX Awards 2026 for the third consecutive year.

How a oneZero integration with MT4/MT5 is structured

A typical setup has four layers: client terminals, your MetaTrader server, the oneZero Hub, and the liquidity providers. Prices flow up from the LPs to the platform, and client orders flow down to be filled, hedged or warehoused under your rules.

 Clients (MT4/MT5 desktop, web, mobile)
              |
   Your MT4 or MT5 trade server
   (groups, symbols, swaps, margin)
              |
   MetaTrader bridge / gateway
              |
   oneZero Hub (dedicated hosted instance)
   aggregation - markups - warehouse - hedging
              |
   Liquidity providers (via EcoSystem / FIX)

The Retail Hub page lists the main functions that you configure in the Hub: "pricing and risk management, aggregation, warehousing, market access, price distribution", together with Warehouse Controls, a Margin Engine, Risk Management, Aggregation and Pricing & Spread Controls.

Your MetaTrader server still holds the client-facing setup: account groups, symbol specifications, trading sessions, swaps, margin settings and plugins. In our experience, many go-live problems come from mismatches between those MetaTrader settings and the Hub settings, not from the Hub itself. Typical examples: a contract size that differs between MT5 and the Hub, a session open in MT4 but closed at the LP, or a group routed to the wrong book.

MetaQuotes states that "the MetaTrader 4 trading platform licenses are no longer available for purchase", so new brokers launch on MT5. If you plan to move, read our MT4 to MT5 migration guide before you design the oneZero routing.

Step-by-step: integrating oneZero Hub with MT4 or MT5

The integration runs in seven stages, from scoping to live monitoring. The order below is the one we use. The duration depends mainly on how quickly vendor onboarding and LP contracts are completed, since FXSUPPORT does not control those.

1. Assess the current setup. We review your MT4/MT5 servers, plugins, groups, symbol list, existing bridge (if any) and risk model, and note what must change.
2. Agree the target design. Which LPs, which symbols, which client groups are A-book, B-book or hybrid, markups per group, and failover rules. This becomes the configuration document.
3. Vendor and LP onboarding. You sign with oneZero and your LPs. oneZero provisions the hosted Hub; each LP issues connection details.
4. Connect MetaTrader to the Hub. We prepare the MT server side: network access, the bridge or gateway connection, symbol mapping and order mapping, trading sessions and DST/holiday schedules.
5. Test on demo, then on a restricted live group. Quotes, every order type, partial fills, rejects, stop-outs, swaps, session breaks and LP disconnects (see the checklist below).
6. Controlled go-live. Move client groups in stages, watch execution and logs closely, and keep a rollback path to the previous routing.
7. Monitor and optimise. Daily checks, end-of-day reports, LP performance reviews with your dealing team, and changes to routing rules as flow changes.

For a standard setup with a small LP list and clear routing rules, our own work on the MetaTrader side is typically scoped at two to four weeks once vendor and LP access is in place. Multi-server environments, both MT4 and MT5, or complex A-book/B-book rules take longer. We give a firm plan after the technical review.

A-book, B-book and hybrid routing in oneZero Hub

Yes, oneZero Hub supports both external hedging and internalisation. The Retail Hub lists "warehousing" and Warehouse Controls among its features, and oneZero's Portfolios feature lets you split client flow into groups that are managed differently.

"Implement multiple real-time risk management strategies concurrently – one group can be internalized, while other groups are hedged smarter."— oneZero, Portfolios (accessed October 2026)

oneZero states that "one Portfolio is included; add more as you wish", that Portfolio tracking is included in its Data Source Insights Essentials package, and that Systematic Hedging and Settings Schedule are available for automation. Its Institutional Hub adds ESP and RFS protocols and an Algorithmic Pricing Module.

The Hub only carries out rules you define. Before configuration we help your dealing team write them down:

• which MT groups or account classes go to which book or Portfolio;
• exposure limits per symbol and when hedging starts;
• how toxic or latency-sensitive flow is identified and moved (we maintain toxic-flow lists as part of risk operations);
• what happens to open positions when a client is moved between books.

Routing models carry regulatory consequences that vary by jurisdiction. This page is general technical information, not legal advice; check your model with your compliance adviser.

What drives the cost of a oneZero Hub integration

oneZero does not publish a price list on onezero.com, and FXSUPPORT does not publish prices. Total cost depends on the Hub package, infrastructure, number of LPs and servers, and how much ongoing support you need.

oneZero's Retail Brokers page says it offers "different packages to suit all broker types, from start-ups to enterprise grade brokers", with the option to upgrade as the business grows. When you budget, separate these items:

What to prepare before you contact oneZero or FXSUPPORT

A short preparation pack lets vendors and integrators give you an accurate plan and quote. Collect the following before your first call:

1. Platform details: MT4, MT5 or both; build numbers; number of trade servers; where they are hosted.
2. Symbol list with contract sizes, digits and trading sessions, and the LP symbol names if you already have them.
3. LP list, with the status of each agreement and connection details.
4. Routing model: which groups are A-book, B-book or hybrid, and your exposure limits.
5. Existing plugins and bridges that touch order flow, such as risk, copy-trading or MAM/PAMM plugins.
6. Reporting needs: internal reports, LP reconciliation and regulatory reporting.
7. Target go-live date and who signs off on testing.
