New York Stock Exchange opening

Hello everyone.
I want to know....the New York Stock Exchange opening is 8:00am or 9:30am?
Which are times where it is better not trade because we are near the opening of a market?
Many thanks and happy pips :-)

09.30 New York time. Trade it any time during the day here in Europe - you can trade the futures if you use 24 hr charts, and it closes at 17.30.

Thanks for the answer.
Why,in homepage of this site,is written that the opening is 8:00am ?

Openig bell 9:30 AM NY time
Closing Bell 4:00 PM NY time

8:00 - 9:30 Pre market trading
4:00 - 6:30 After hours trading

Is better not trade at 8:00 Ny time? What is Pre-market?
Thanks Ace66

all major news are usualy at 8:30...or 10:00 pre market is that you could trade stocks before the wall street open but without the major players fully in....
9:30 is when the overnight orders kicks in (if there is any) its like in forex any opening is Potential for a Liquidity spikes......SO it depens if you look for it to get in or you just want to wait and get in after 9:30 and see what's going on... wait for new HH or LL...
