I would like to be able to completely remove a given stock (or any other instrument) from the windows labelled Position Statement (It's under Monitor-->Activity and Positions). I can't figure out how to and I have had no luck searching Google. I know how to close out a position but once I do, I want have the ability to remove it from my sight. Thank you in advance.

When you close a position it stays on the list until the next day, then it does not appear anymore.

This doesn't seem to be the case for me. They just hang out for weeks.

I agree with JP, it stays around forever for me too. Current position entries disappear when closed but Unallocated (which seems to be a system generated group) just seems to stay constant.
