hi, I've just started to trade options, and there is sth concerning iron condors that I can't understand. initially, I believed that I wd make money on my iron condor if the price will end up somewhere between my short call and short put. But I realised that the price behaviour of the condor is much more complex: one day, as the price started to depreciate quickly, my p&l also started to get lower, so I found myself with a position which was theoretically profitable but in reality with Delta about 33 I was deep in the red. So now I really not sure how the price of IC is changing. My biggest questions are: 1) Is it still correct that if at the day of expiration the price will finish between my short call and short put I'll make money on this trade (meaning full credit received)? 2) additionally, why the IC price changes so much when I'm just getting close to one of my shorts? will this change of the price result in my losses even if the price at expiration will stay between the shorts? 3) Do I need to pay attention to current P&L if I'm really interested in my spreads expiring worthless? 4) in software like OptionVue you can watch your position profitability level (like 6-8-10%). What does this figure really mean? Say I received a credit of $500 with margin requirements of $5k. Does this 6% mean that I need to exit my position if P&L is just (6% of 5000 = $300) - and this way i'm not going to wait to the expiration at all? thanks in advance.
