In the Book Trade workspace, you can search for the account and/or security for which you want to process the transaction. You must identify the security at a minimum.

To search for the security for the trade:

1. From the Book Trade workspace, click the Search drop down on the ribbon and select New Search, Last Search, or any saved search. Or, click the double arrow to the right of the workspace to expand the Search Detail pane.
   You see the Search Details pane.
2. Complete the search criteria.
   You can specify a value in the Entity ID, Xref Type, and/or Xref ID fields or can click the Entity ID or Xref ID arrow to select a different entity or security option. Or you can click Add Search Criteria to manage the search criteria that appear.
3. Click the Search button in the Search Details pane.
   You see the search results based on the criteria you selected. Your search criteria appear to the left of the workspace header.
4. If you want to save your search criteria, click the Save or Save As dropdown and enter a name for the search.
5. In the Grid tab, you can use the options to manage how data displays for the search results.

After you specify search criteria and review the search results, you can select a security from the search results and process a transaction for that security. The system uses the entity/or and security you selected in the search criteria as default values in the transaction entry panel.
