The Default Amount (DA) is the default order size. This is the number that initially appears in the Amount field when an order is created. You can set a different default amount for each account. In the Account Information window, left-click the “DA” field. The “Default Amount” dialog box will appear.

 

 

Enter the new DA, and then click OK.
