Yo Irishbull, A guy at TD Ameritrade told me that when you sell a stock you can buy another stock right away with the proceeds but then you must hold that new purchase for at least the 3 day "buy" settling period of the previous stock purchase?
He also said the 3 day settling period only applies to the buy end of the trade, not the sell end of the trade.
I'm confused a little here but maybe I missunderstood TD rep.
