I am new to Interactive Brokers and have been having a lot of problems with its TWS platform (both web-based and standalone). It will slow down after a couple of hours and then it would just freeze. I would have to use the Task Manager to shut the program down. This continues to be a problem despite trying a number of things, including uninstalling and reinstalling Java and TWS, recreating a new profile, increasing the memory allocated to TWS (i.e., from 512MB to 2048MB). I've been trying to get Technical Assistance to help me, but nothing has worked to solve this problem. Another problem that I have been experiencing is the long delays in creating a new chart...it has taken as long as 2-3 minutes for it to load the data. I don't know if anyone else has encountered either of these two problems, but any comments or suggestions would greatly be appreciated.
