If your two accounts are linked, be careful- you can't bid from one account and have shares up for sale in the other at the same time (and perhaps in a short period?)- I learned that the hard way when I tried to do that (but the other way around, and for different reasons) with TPWR a bunch of years ago- got an immediate call from E-Trade - since it was an "innocent mistake" (which it was, for the most part, although my spidey senses were tingling a bit), I got off with a warning- otherwise I was looking at an at least 30 day suspension from trading in the account. Check and make sure all is Kosher before trying to implement anything like that- buying and selling "to yourself" wreaks of manipulation! As they say on TV, the more you know!
