Mom, I have a real stock account. If you want to buy stock short, it acts the same thing as buying on margin. When you buy the stock short, you sell so many shares. Then hope it goes down. If it goes down, the stock becomes covered (?) and then you can buy it back any price you want. I also asked them and they answered back this explanation.
Got it, Mom?
On your transaction, did you make it the night before. I f you did it the night before, when the market opens up, it tends to jump right over your limit price.. Don't forget, the overseas markets are open before ours are. These markets tend to dictate some difference in where our market closed one day and where it will open on the next. Unnderstand?
