Subject: Re: OT: Premarket trading
Probably a misunderstanding: I am this moment on Schwab´s option chain screen. The bid/ask for the options do not change (which is why I asked; now I know why not. Thanks, Jim). What changes is the premarket quote for Berkshire stock.

Ok, going to bed now here in New Zealand. When getting up at 7am it will be already 2pm in New York, with me having missed most of the trading day then. But I am not willing to sacrifice my sleep for money :)
