1. Your Questions About Nasdaq After Hours
Nancy asks…
What are Pre-market trading hours and After-market hours?
In NASDAQ, what are the Pre-market trading hours and After-market hours? I guess buy/sell
order can be placed in this hours but execution can only take place in trading hours?
Can anybody elucidate?
Steve Winston answers:
As for the hours, each exchange and ECN has their own trading times. I believe NASDAQ and
NYSE Arca starts the pre-market session at 8:00AM and ends after-market at 5:00PM. ECNs
generally have much longer trading hours, and the earliest begins at 4:15AM and ends at
7:00PM.
Like the two previous posters wrote, liquidity during pre and after-market hours tends to be
extremely thin for most stocks. In generally, on the most liquid stocks and ETFs are traded
during those times.

2. Sharon asks…
Are Electronic Communications Networks / ECNs for Stock Market
open 24/7 or is there times when they r closed?
I am looking at GM stock charts on Nasdaq after hours but it does not show the date . I am
thinking the chart is showing Wednesdays data since normal trading ended early plus it likely
was closed for Christmas. I will propbably have to wait for Pre-Market data. Is there other times
when institutional investors do not have access to ECNs?
Steve Winston answers:
No they are not open 24/7. For example Nasdaq extended trading is 8:00-9:30 AM Eastern
Time and 4:00-6:30 PM Eastern Time.

Then I go on Ameritrade I get another, and finally on go on the Nasdaq site and I get another.
Steve Winston answers:
The same reason there isn't one restaurant to go out for dinner...
I'm not sure I understand your question.
