hahaha. no you would not be that is true but if u are more than a bid offer in the size of the notional itm it would be strange not to. so i think they decided the opt out of really mental shit option is easier so you would have to tell them but prob better than them not exercising if you forget.
oh actually i see ur point say u are long a call option requiring less margin then then delivered underlying and they exercise it and causes problems.
You should REALLY take Gussian's suggestion. Stop until you understand more, you are missing some key concepts of the options world.
1. If u make a deal with the broker that you wont exercise your option and he will not foce clise it. You have the free dom of gamblųng in the market for 2 whole hours and either expire your option of @3:45 pm stock price rises 30% and you sell your option making a lot of $. But in this case brokers comission is not guaranteed in case of stock going down. 2. Stop/loss.. nice so the stock price is going up constantly for 20 min and ur chanhing stop loss every 5 min. Fair enough. 3. Science Yo. Lets do this. So we have a theory: "Analysis was wrong, im guessing the analysis means that the stock will be up right(long call option)? But when @ the expiration time? 12pm/2pm /4pm.." So if we fail to prove this is wrong, this is correct by default. 1. Stock has to be dow the whole day.. from open to close(false, stock was down for 15 min from 2pm ) On open it was +3% 2h later +7.5% @2:01pm 0% up 4pm 5% up... 2.if the analysis would be compl wrong yes ur right but in this case its not 3.
