Continually need to relog on TWS...

What is the % CPU usage during the problem?

 

and Ram, hence asking about taskmanager

 

I did a few tests. CPU usage peaked at 50% a few times on the 3rd screen of the "performance" window, but not when it froze, just on the preceding attempts when the charts ended up being displayed after a long load. RAM is a flat line at 1.4 Go

 

sounds like bummer charts then unless some IB chart users come to the rescue. I think you better not hold your breath for that

You have good charts already so why use IB's charts?

 

CTS only display 2 contracts per chart. These IB charts are really fine for what I want to do, the only problem is the freezing.

 

try a free trial with Sierra Charts. Sounds like the basic will meet your needs and you'll not have problems

 

I wonder if it doesn't have to do with the 100 Tickers limit on IB too. I don't think so as 100 is the limit for simultaneous load, but I am not sure.

It seems I can load as many 5 instruments charts as I want, but when I try to load one 20 instruments chart on 5 min frame, it freezes...

 

I tried with my laptop ( 4Go RAM ). Same Problem.

 

Has the problem been resolved?

 

Are you running the latest java release? When I upgraded mine all hell broke loose. Are you noticing any error messages ever?
