...however, to IB's credit, when TWS and data are working as should, it's an outstanding platform...
Quote from spyderman:
Huge range week, with alot of movement, volume and quote changes.......all of which can cause problems and exploit any system weakness's. I traded actively all week YM ES NQ DAX ESTOXX and had 1 TWS outage of perhaps a minute. Even when prices moved extreme I noticed very little lagging of the quotes....Qcharts on the other hand lagged huge.....for perhaps a minute max in some instances.....albeit...this didnt happen very often. That matters little to me as I just use them for charting and not trading off of.
However these two are not my only sources of quotes, and if you are serious about trading, the more redundant you are the better.
I think some of you have some ISP/Bandwidth/processor problems.
ps.....curious thing.....for the past 45 days I've been using an AMD 64bit processor based pc instead of prior Intel's..(32bit)....compared to them, "freezing" problems of any kind have virtually dissappeared. Wonder if this is just coincidence?
Quote from Arnie:
TWS has been locking up for 10-30 sec every few minutes or so. I have exhausted every other posibilty...router, isp, computer. I call them again today and explain that on same computer with Mytrack and TWS, you can clearly see TWS locking up while MT quotes are coming in. They say they have NO REPORTS of this problem from anyone else today. These people are unreal. Any suggestions? Maybe a new broker?![]()

I had this exact problem. This is sometimes combined with the grey TWS window problem, slowness in loggin in, TWS dropping the socket connection, no quotes on the quote line or slowness in processing orders. I've had and corrected this problem twice so far. These symptoms can appear in combination, but the most common effect is the socket connection being dropped (two or three times an hour with slowness in re-loggin in).
A properly functioning TWS does not have this problem and I don't think the problem is in the server.
I have verified an issue with the *.lyt files in the XML directory becoming corrupted which can cause these symptoms in TWS. When I say verify I mean that I had these problems so I deleted the XML directory (allowing TWS to create clean files on the next startup). This fixed the problem (but I lost my pages, personalizations and hotkeys). Then I fed in the old *lyt files one at a time until the problem reappeared.
Think about what's happening. You upgrade to a new version. Suddenly you lose your pages or hotkeys (telling you TWS can't read a file). Then you get this instability with your connection which you blame on the new version itself.
But think through whats happened. You already know that some *.lyt files have been corrupted (which is why you lost your pages or settings or hotkeys). Then TWS behaves in a way which is consistent with the file corruption issue that I verified.
The problem is *.lyt file corruption, not the IB server and not the TWS application upgrade itself.
Anyone with these TWS problems should peform this test. Save your XML directory to a new location (the one named with random letters C:\Jts\dsxcsy). Delete the XML directory in the JTS folder. Restart TWS and see if the problem is solved. You can copy back your data stored in the XML directory after you've done this test.
