Equity option in pre-market

Is there any trading of U.S. equity options outside of normal trading hours?

Occasionally I've seen quotes on equity options during the pre-market, primarily on ISE, but have not been able to execute at the prices listed - the orders are accepted by the exchange but sit un-filled.

Thanks.

 

No, equity options don't trade in pre- or post-market.

 

Thanks for the confirmation. The pre market quotes must be a glitch in ISE's system.
