I have bought 300 share of one stock and leave it overnight on Friday. when I open the account on Monday, I discover that there is ony 200 share. What has happened? I request the filled report from the rubbish company, they told me that one share is automaticlly sold by the system. The filled price is far away from the market price. The market price is about 20, it is filled at 10. I ask the rubbish company to compensate, they told me that according to the agreement they has no responsiblity. Suppose that you have bought 1000 share of goole at 600 on friday and close the account, then the people sold them all at 300, what will you think! Leave as soon as possible.
