# How do I block orders?

You can group one or more orders for the same instrument into [blocks](/v1/docs/what-is-order-blocking-in-lusid), ready for placement.

There are several ways to create an order block in LUSID:

- [Using the Order Blotter in the LUSID web app](/v1/docs/how-do-i-block-orders#using-the-order-blotter-in-the-lusid-web-app)
- [Using the LUSID REST API](https://www.lusid.com/docs/api/lusid/endpoints/blocks/UpsertBlocks)
- [Using Luminesce](/v1/docs/lusidblockwriter)

## Using the Order Blotter in the LUSID web app

You can block one or more orders at a time using the Order Blotter in the LUSID web app. To do so:

1. Sign in to the [LUSID web app](https://www.lusid.com/app/home).
2. Navigate to **Portfolio Management > Order Blotter** via the top left menu. ![](https://cdn.document360.io/d575ad81-c0ed-4980-bbd1-d59ac5c3de82/Images/Documentation/image(764).png?sv=2026-02-06&spr=https&st=2026-11-09T06%3A00%3A04Z&se=2026-11-09T07%3A00%3A04Z&sr=c&sp=r&sig=ZMpKDONV7NO3805DbEB2Vcz%2BSjlVfQk9GX789d7NehQ%3D)
3. Select the orders you wish to block together. There is no limit to the number of orders you can add to a block, but they must have the same:

  - **Lusid Instrument ID** (LUID)
  - **Side**, for example `Buy` or `Sell`
  - **State**, which must be `New`
  - Order **Type**, out of:
    - `Market`
    - `Limit` with the same **Price** value
    - `Stop` with the same **Price** value
  - **Time in force**
4. Select the **Options** icon > **Block all relevant**. LUSID blocks all applicable orders and leaves inapplicable orders selected. ![](https://cdn.document360.io/d575ad81-c0ed-4980-bbd1-d59ac5c3de82/Images/Documentation/image(626).png?sv=2026-02-06&spr=https&st=2026-11-09T06%3A00%3A04Z&se=2026-11-09T07%3A00%3A04Z&sr=c&sp=r&sig=ZMpKDONV7NO3805DbEB2Vcz%2BSjlVfQk9GX789d7NehQ%3D)

Provided your order block has passed a [pre-trade compliance check](/v1/docs/how-do-i-perform-a-pre-trade-compliance-run-and-view-the-results), you can place your order partly or in full. [See how.](/v1/docs/how-do-i-create-a-placement)

You can perform custom actions on one or more order blocks by running a **Block job**. [See how.](/v1/docs/using-block-jobs-in-the-order-blotter-dashboard)
