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?
Ok, what i meant was Purchasing a Call with the anticipation the price of a stock will go up in value upon expiry
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.
And if you have insufficient funds but ignore the margins call? They will auto-liquidate and hopefully you end up with a profit after transaction costs?
If your options are in-the-money by $0.01, your options will be automatically exercised on option expiration day
