IB NYMEX trading hours

Hi, according to IB's website, the trading hours for NYMEX are
00:20 - 16:15 (ET) (1)
16:45 - 21:15 (ET) (1)
21:30 - 23:00 (ET) (1)

http://www.interactivebrokers.com/cgi-pub/exchange_display_web.pl?einfo=usNYMEX2&file=NYMEX.html

is it the case that QM and QG are NOT tradable between 16:15-16:45, 21:15-21:30 and 23:00--00:20 with IB when the prices are still fluctuating? Quite strange.

Thanks.

 

It's best to check the hours for each product on the exchange's website, since it's not possible to accurately list just one set of hours for an entire exchange, though IB tries to give a general idea of them. Most products are tradeable during the exchange-listed trading times that do not coincide with IB's scheduled downtimes (see http://www.interactivebrokers.com/en/software/systemStatus.php?ib_entity=llc ), though there are exceptions.

According to http://www.nymex.com/QM_spec.aspx , the trading hours for QM are:

Sun 7:00 PM – 9:30 AM
Mon – Thu 10:00 AM – 2:30 PM, 3:15 PM – 5:30 PM, 6:00 PM – 9:30 AM
Fri 10:00 AM – 2:30 PM

and http://www.ecbot.com/cbot/pub/page/0,3181,932,00.html#metals says metals trade 20:16-17:00 ET.

Also note that you will sometimes see bids/offers in a different color to show orders being entered prior to the actual opening.

 

I see that right-clicking on a ticker and choosing Contract Info->Details results in a page that now shows detailed trading time information.

It's important to note that these times are local to the exchange (i.e. ECBOT times are in Central).

Now, if I could understand why YM, ZG, and YG quotes are shown in the "pre-opening" color at the moment (19:56 ET)...

 

thats because they are not open yet !

10-2:30 are the big hours, the rest seem to be range-bound computerized quotes.

 

Even though I did the conversion when I wrote it, I was still looking at the 19:15/19:16 opening times and thinking they were supposed to be open (forgetting to convert to ET). I'll note that I did see values in the Last and Change columns which confirmed my thoughts that they were open already. I'd expect to see "C" values and blank changes.
