回复：Apprentice ASK: what is the difference betweem margin

I was told by the stock company that if I have margin account, i have to keep the same positions (sell and buy some amount,same stocks in the same day) although there are no limits about how many trading made, otherwise I will be considered to have borrowed money for the openings that I make during the day. And if I sell the opening next day, I will be charged one day interest 10% for the openings. Is this right? Based on you guys posts, I did not get the same info as that from my stock company.confused?
