Hello i just wanted to clear up some queries i have of futures and options.

Firstly is the profit of options worked as the increase worth per share minus premium and any put or hedge options.

Also are futures the same thing but you have to keep topping up the margin account and can loose a lot more . Say though after the first week the exercise price increases is your bank account debited for the profit or does it stay in the margin account as a buffer zone incase the price goes down.

When you buy options and futures does a broker give you a document explaining the date of expiration , what happens if you forget to sell.

Thank you

p.s are futures and options void of capital gains
