Hi, I have a question. I am opening an account with TOS and I build my options portfolio but I have a problem. it's just a sample. I have 25000$ I want trade a title XYZ to 48$ I sell 10 call to 50$ and buy 10 call to 51$ the maximum risk is 1000$ the marge is 1000$ but if the title is to 52$ I am assigned but I have not the 51000$ to buy the coverage and give the title. how TOS manage the position ? thanks,
