Hello everyone

Im kinda new to options. But i have a question. if the stock is 550 and i buy a strike price at 590 with call price at 0.30x100= 30 dollars. after one day the stock went to 560 and call price is 0.60. thats means i have 30 dollar profit if i end the trade right. or do i get my 30 dollar only if the stock reach 590. its a american style btw could some pls help me with this question?

Yes, you can close out your position at any time before expiration to lock in the profit.
