You can attach a note (memo) to an order via the Memo tab. However, you can only view the memo if you’ve added the Memo field to the Message Monitor’s Message view.
Complete the General tab (and the Advanced and/or Special tabs, if applicable).
Click the Memo tab.
Select a memo from the Memo drop-down list box, or if the memo you want to submit with your order is not available, type it, and it is automatically saved to the list.
Memos are limited to 30 characters.
When you have completed the Memo tab, you can click [Submit] to submit the order. Optionally, you can modify the Advanced, Special, Exec Instr, and/or Scale tabs to further customize your order entry.
