Quote from pipscooper:
MidKnight,
One of IB's reps mentioned on the boards that they were phasing out the system restart time that used to take 45 mins or so.
From my observations and what one rep said: the restart time is 11:50 PM Eastern time. I set my auto logoff time to that time, then I reconnect. When I get back on quotes continue until about midnight. At about midnight Eastern quotes either freeze or go blank until approximately 12:06 AM Eastern. A TWS restart often brings quotes back online before that time. Quotes run continuously from that point on.
There is one other thing to watch out for. If you are collecting quotes, at about 12:10 AM Eastern on one of my accounts and about 12:30 AM on another account the purple *reconnect* lines come on the TWS for about a minute. After that time my TWS API program stops collecting quotes so I manually restart it.
From what I can tell they are still working on the restart - it has been getting smaller and smaller timewise for the past few weeks. I haven't seen an official announcement on this - just my first hand observations.
I have had some trades on, and have placed trades between 11:50 PM and 12:10 AM Eastern and it works. I am not usually actively trading at that time, however as the TWS is not 100% reliable during those times (sometimes quotes go out for a minute then come back on, sometimes have to restart TWS to get them to come back on).
To add to the good info provided by pipscooper: TWS auto logoff time (Configure - Misc) can be set for
any time of your choice. As far as I know, there is nothing special about midnight or thereabouts. Mine is set for 5:07 pm EST. Why?
- it's the optimal time for me, as some time between 4:30 and 5 pm -- 2 minutes before that (Windows foreground-insistent) Java logoff window pops up at 5:02 -- I have already saved all reports and screen shots I need for the day;
- IDEAL Pro forex quotes are not available between 5 - 5:30 pm, so nothing is missed, e.g., for charts, by scheduling auto logoff during that interval;
- immediately after auto logoff I login back into TWS at 5:07 and hit "start" again on QuoteTracker, my API charting app. This is the only time in any 24-hour period that I have to manually launch and login into TWS.
The IB US server reset begins for me at midnight and is completed within a few minutes (3-6, typically). I believe this may vary slightly for different accounts. During that time, orders are still visible and live, but there are no live forex quotes.
The other auto reconnect mentioned above happens for me around 12:35 am and is completed within 1 minute. Ditto regarding orders and quotes.
