Quote from Samc:
Does anyone know if there is any "official" time for options to begin trading each day?
I know I have been in options positions and had to sit the first 15 minutes of trading watching a big move in the underlying from the open until there was a B/A for the option?!?
Thanks
I think, generally, options start trading in sync with the underlying stock, but in practice it can mean a few minutes delay (in some cases 15 min and more when the stock is excessively volatile). If you want to lock in gains on an options position you can always trade the stock to neutralize deltas and then close the whole position out when the bids/offers are posted.
