Instinet Trading Hours

S

I am curious what hours your broker lets you see the NBBO
or order book for Instinet ECN

my broker gives me access to Instinet from 3 am to 6:26 pm
approx EST

I have seen their NBBO quotes sometimes earlier than 3 am
and it seems Instinet might have different hours according to their website




"Instinet adheres to the following trading schedule:

Trading ends at approximately 6:40pm EST and all orders are purged from the system.
Trading begins again after approximately 5 minutes at 6:45pm as the next trading day.
Friday evening from approximately 6:40pm to Sunday evening at approximately 7:30pm orders will not be accepted by the system but stocks may be quoted."
 
I now see bids and offers ( NBBO )

starting at 1 am (? )

with my broker but I cannot execute until 3 am

in the past I could not even see the NBBO

for Instinet until 3 am
 
is that Instinet is not making a market for any size in

the QQQ + SPY this pre am 4:30 am EST

perhaps by 6:00 am they will EST
 
Instinet seems ot be making a market tonight
or tomm ( 138 am est )

wonder how come if these quotes are real

they were not doing anything yesterday until

late morning pre market ( perhaps 6 am )
