I've read this on options, but my questions are not answered there. So:
If I buy a put/call option on IG, when exactly does it settle? I can see dates for the options, but not times, and
Is it the case that all options are exercised at expiry and only then? i.e. I can't exercise them before the expiry date and time, and exercise takes place automatically at expiry if in the money, such that I don't have to do anything?
Thanks.
