I have Scottrade also. They are self clearing, so you can buy and sell w/o any trouble. Since the chill, I have picked up over 2 million shares. I was lucky to have Scottrade from the start.
On cash accounts, if you have a Scottrade office nearby that you can drop a check off at, the funds will available for trading the next day, sometimes sooner. Bank transfers take 3 days to clear. Go figure!
Go get 'em lowjack!
GFTYA!
