FIX Connectivity

One FIX Connector for Multiple Margin Accounts

A single FIX connector can serve many margin accounts on a hub. The taker platform names the account on each order in the standard FIX Account field, and B2CONNECT routes the order to the matching margin account.

FIX connectors

From a Connector per Account to One Shared Connector

Previously, every margin account needed a FIX connector of its own.

Previously

3 FIX connectors

Each margin account required a separate FIX connector.

FIX 1Margin account 1

FIX 2Margin account 2

FIX 3Margin account 3

Now — B2CONNECT

1 FIX connector

A platform running several White Labels, or serving a large number of end clients, keeps them all on one connector, with each account's positions, margin, and commissions kept entirely separate.

How it works

The Platform Names the Account, B2CONNECT Routes It

The Order Names the Account

The taker platform sets the owning margin account on each order in the standard FIX Account field.

Tag 1 (Account)

B2CONNECT Routes and Confirms

B2CONNECT routes the order to the matching margin account and returns the same value on every execution report.

The Client Reference Reaches Reporting

The client reference sent with an order is stored with the execution and appears in the Trading Report under Hub Reports.

The Account Identity Reaches the LP

Account (Tag 1) and, where enabled, SenderSubID (Tag 50) and OnBehalfOfCompID (Tag 115) travel with the order to the liquidity provider and come back on the execution report, so the provider can tell each account's orders apart.

Fills Traced Back to the Client That Placed Them

The client reference sent with an order is stored with the execution, so back-office and reconciliation teams can trace any fill back to the end client that placed it.

Why it matters

One Connector, Separated Books

Many Accounts per Connector

One connector can serve many margin accounts instead of one connector per account.

Fully Separated Accounts

Each account's positions, margin, and commissions stay entirely separate on the shared connector.

Traceable to the End Client

The client reference is stored with the execution and reported in the Trading Report under Hub Reports.
