T.C., "Fully Paid" would tell me that it was a CASH ACCOUNT. Is your account a MARGIN ACCOUNT with a portion of FULLY PAID, and A PORTION ON Margin?
I ask this because TD WATERHOUSE may have their own rules, whereby other brokers act differently.
I have three accounts with Waterhouse, one of which is a small MARGIN ACCOUNT. (about 4,000 shrs.)
I asked TD W. not to loan or rent it out. He said
OK, "it's done."
