Is anyone else having trouble with data not coming back after the midnight reset? It seems that this week I have had this happen 3 times on two different TWS instances. Data stops for certain products just after midnight and no trading is possible until a manual restart of TWS. Obviously, this adversely affects automated trading and short of staying up to midnight every night how can this be worked around? It always seems to be the same servers (the ones carrying data for CL/NG/RB for example) and I think it is the cusfuture farm but I could be getting that mixed up. Either way, this seems to be a regular occurrence now that I have upgraded TWS past 906. I am currently using TWS version 906.9 when having this issue. Incidintally, I have run TWS versions before the forced upgrade through the midnight reset and maybe 1 in 100 times this happened. This week is 3 for 5 . As a side note, what is the actual purpose of this midnight reset? Is there some memory leak that can only be corrected by a daily reset? I have still never heard a clear explanation as to why this practice is even necessary in the first place. My other brokerage account with a TT feed is clean and clear all night long so I know this is not an industry standard practice and I've only ever seen it at IB.
