For me, the quotes would just freeze on a few stocks, then slowly on some more, then they would disappear completely across the board. Right now I am using the browser version instead of the standalone. It seems to be working ok. IB tech showed me how to transfer all my settings from the standalone version to the browser version. This was a relief as I have about 100 stocks set up with various routing options. Does anyone know the pros and cons of using the browser version as opposed to the standalone version? I must say that, even although this has been a problem for the last 2 days, IB tech has been responding as well as can be expected via email. I'm sure (hoping) this problem will be ironed out shortly with the next build.
One main con of using the browser version is that if your internet explorer crashes, so does TWS. But I still use the browser as a default because the standalone doesn't work as well on my system for some reason.
I've been having similar problems with my quotes since I upgraded to the latest stand-alone build a couple of days ago. For me, it starts whenever an order goes live: A few seconds after that quotes get slow, then incorrect, I even get negative numbers, then they disappear completely. The solution is to restart the TWS, which I have been doing after EVERY ORDER... I would like to use the browser based version while they are working on the standalone one (unfortunately I was too stupid to save a copy of the old version). How exactly do you transfer your settings to the browser-based one?
I also suffered yesterday with the missing quotes and negative values and other funny stuff on my standalone version of the TWS. I called the IB Tech desk this am and was told to use the website version of the TWS for trading. this seemed to fix all the problems I was having thursday.
Kleinphi This is a copy of the email I got from IB tech. "Log out of all of your instances of TWS. Go to my computer, the C: drive, and then to the JTS folder. Hold down the ctrl key on your keyboard, and single-click on all folders in here that begin with the letter "d" and go up to edit and select copy. Click back once, then go into the ibjts folder. Go up to edit and paste. Say "yes to all" to replacing the folders. This will copy all settings into the web version for you; unfortunately, we don't have an older standalone available."
