It should go through. I have Scott trade and the trades go through on the day I make them. The money has to settle for 3 days. They don't like it when you use unsettled funds which happens when you use the same funds to sell, then buy, then sell again. They call it a free ride. They let you know about it. When your funds are fully available, it should be approved the same day. Even SGMD.
If you actually bought on Friday you should have already received conformation unless it was an unfilled "limit" order or you put some other condition on it that wasn't met by the time period you specified. Either way you should have received some kind of notice.
If the trade went thru, you're golden. It still takes 3 days to clear the trade but if the trade executed then you're a shareholder!!
The activity should be recorded in your account, have you looked?
