[See the full list.](/v1/docs/which-instruments-can-i-order-using-lusid) > [!NOTE] > Prerequisites > > To get started, [contact your FINBOURNE representative](/v1/docs/how-do-i-use-the-support-centre) to enable the integration in your LUSID domain. **Further reading:** [Understand how LUSID’s order management system works.](/v1/docs/understanding-how-lusids-order-management-system-works) ## Supported data types and methods ### Instruments See article: [Which instruments can I trade using LUSID?](/v1/docs/which-instruments-can-i-order-using-lusid) ### Order entities and connection types You can use LUSID to [stage orders in an **execution management system (EMS)**](/v1/docs/understanding-how-lusids-order-management-system-works#using-lusid-to-stage-orders-in-an-ems) with FIX messages that interact with the following entities: - Placements - Executions You can create orders in external systems (including EMS) and store records of any of the following entities in LUSID via [**drop copy**](/v1/docs/understanding-how-lusids-order-management-system-works#creating-orders-externally-and-storing-a-record-in-lusid-via-drop-copy): - Orders - Blocks - Placements - Executions - Allocations ## Setting up the integration All FIX trading integrations have a corresponding shared configuration set in the [Configuration Store](/v1/docs/configuration-store) that you must populate with the relevant values. To do so: 1. Navigate to **System Settings > Configuration Store** and select the **Shared Keys** tab. 2. Locate the relevant configuration set with **Scope** `system` and **Code** `FLAG-<external-system>` and select **Edit**. ![](https://cdn.document360.io/d575ad81-c0ed-4980-bbd1-d59ac5c3de82/Images/Documentation/image-59SQ3PZR.png?sv=2026-02-06&spr=https&st=2026-11-09T06%3A50%3A21Z&se=2026-11-09T07%3A50%3A21Z&sr=c&sp=r&sig=NZ%2BSLNcAagbgapc%2B3RzyAhICkxd0HIR5N0V4sS%2FXYHU%3D) 3.

How you trade depends on your integration type: - [EMS](/v1/docs/understanding-how-lusids-order-management-system-works#using-lusid-to-stage-orders-in-an-ems): Stage trades using the [Order Blotter](/v1/docs/using-the-order-blotter), then place them via your EMS - [Drop copy](/v1/docs/understanding-how-lusids-order-management-system-works#creating-orders-externally-and-storing-a-record-in-lusid-via-drop-copy): Trade using your external system and monitor your records in LUSID ## Monitoring and troubleshooting integration runs You can view your integrated placements and executions in LUSID via **Portfolio Management > Order Blotter** or **Order Management**. LUSID stores each record under your chosen [EntityScope](/v1/docs/bloomberg-emsx#entityscope): ![](https://cdn.document360.io/d575ad81-c0ed-4980-bbd1-d59ac5c3de82/Images/Documentation/image-M8FA1R3V.png?sv=2026-02-06&spr=https&st=2026-11-09T06%3A50%3A21Z&se=2026-11-09T07%3A50%3A21Z&sr=c&sp=r&sig=NZ%2BSLNcAagbgapc%2B3RzyAhICkxd0HIR5N0V4sS%2FXYHU%3D) To monitor and troubleshoot FIX messages LUSID receives and errors that occur on the LUSID side of the process: 1. Navigate to the **Order Blotter** and enable the **Details** grid. ![](https://cdn.document360.io/d575ad81-c0ed-4980-bbd1-d59ac5c3de82/Images/Documentation/image-MGWSZ47F.png?sv=2026-02-06&spr=https&st=2026-11-09T06%3A50%3A21Z&se=2026-11-09T07%3A50%3A21Z&sr=c&sp=r&sig=NZ%2BSLNcAagbgapc%2B3RzyAhICkxd0HIR5N0V4sS%2FXYHU%3D) 2. Click the **Configuration** icon in the **Details** grid. ![](https://cdn.document360.io/d575ad81-c0ed-4980-bbd1-d59ac5c3de82/Images/Documentation/image-24Z7OMCZ.png?sv=2026-02-06&spr=https&st=2026-11-09T06%3A50%3A21Z&se=2026-11-09T07%3A50%3A21Z&sr=c&sp=r&sig=NZ%2BSLNcAagbgapc%2B3RzyAhICkxd0HIR5N0V4sS%2FXYHU%3D) 3. Select the following columns to add to your dashboard: ![](https://cdn.document360.io/d575ad81-c0ed-4980-bbd1-d59ac5c3de82/Images/Documentation/image-59CKRVLS.png?sv=2026-02-06&spr=https&st=2026-11-09T06%3A50%3A21Z&se=2026-11-09T07%3A50%3A21Z&sr=c&sp=r&sig=NZ%2BSLNcAagbgapc%2B3RzyAhICkxd0HIR5N0V4sS%2FXYHU%3D) - `<entity>/FIX/Error`: Displays errors that occurred on the LUSID side of the process - `<entity>/FIX/FIXMessage`: Displays errors that occurred on the FIX side of the process - `<entity>/FIX/Text`: Extracts the text from the FIX message and displays it as a human-friendly value 4. Click **Save**. > [!NOTE] > Note > > For drop copy connections, check whether the entities you expect to have been created exist in the **Order Blotter** dashboard. If you think an entity is missing, [contact support](/v1/docs/how-do-i-use-the-support-centre). --- ### Troubleshooting #### LUSID hasn’t created a trade that was executed in my EMS [Follow these steps](/v1/docs/bloomberg-emsx#monitoring-and-troubleshooting-integration-runs) to check whether LUSID received a FIX message for the execution from the external system. - If LUSID received a FIX message, check whether the external system has correctly populated the value for tag `11` or tag `9613` to start with `PLAC-<number>`. - If LUSID did not receive a FIX message, check your integration configuration set is correctly populated. A logical data partition most entities reside within in LUSID.
