Ok, what i meant was Purchasing a Call with the anticipation the price of a stock will go up in value upon expiry
So googling straight bull took me to pornhub...you're going to have to explain what you mean.

And if you have insufficient funds but ignore the margins call?Most brokers will auto-assign you the stock you called.
In fact, I can't think of a single broker that wouldn't. Generally you have to call the trade desk and say something like "hey, I would really like to not own this".
Check the OCC. This really is a trivial question.
Let's say i put in a straight bull trade, which expires in one month. However, after the trade is filled, i totally forget i have an open position. What happens upon expiry if the trade is in the money? Does the system auto-exercise for me?
