When using IB Gateway in connection with MultiCharts 64, I do not get access to the historical market data farm and the status indicator for...
Finally, IB has issued a fix for the Java memory leak issue with TWS beta 940.1p:...
This is very good news indeed. I did some time testing with browser based TWS beta 940.1p and Multicharts64. The memory leak issue seems to be...
I already did this and submitted a log. Just wanted to know if anybody else has experienced this issue.
Since around two days, I do not get any connection to Historical Data Farm, please see the attached screenshot of IB Gateway (in TWS it's the same...
I had another test with these parameters. With this setting, Gateway crashes after some hours as well, after memory usage gets to around 1.1 GB....
And here is the heap usage for Gateway 932.4, for completeness. With this version, Java garbage collection works as it should and no freeze occurs.
Files size of the log file was too big. Another try with zip:
ddecker, below is the log for IB Gateway 938.1f. I'll have another test with the parameters you suggested.

Below is the heap usage log of TWS 938.1f on Win 7 64 bit with Java 1.7.0_21, API client is Multicharts 64. TWS froze after 3 hrs. The log...
pfranz, maybe the issue occurs only for the specific combination of Multicharts and TWS/Gateway 933+? But that's pure speculation, I didn't try...
I tried to integrate the Java log commands you suggested into the TWS shortcut target field, but there is a limitation of characters. Then I tried...
Yes, it's not real tick data, but more a "consolidated" datastream that updates every few seconds.
Maybe you want to try to plot in your application some charts of tick data for some Futures intruments (CL, GC, YM etc.) with a historical data...
That's exactly the way Multicharts handles it: historical data is retrieved from locally stored data and only the "gaps" are downloaded, when this...
pfranz, thanks for your reply. I really appreciate this. I've had a test run with Wise Memory Optimizer. The tool has a remarkable effect:...
ddecker, I am not quite sure if we are on the same page. That you do not have any memory issues with TWS 930.5 is perfectly consistent with my...
Thanks for confirming that there actually IS a memory leak with TWS 933.5. If you try the more recent TWS versions as well (up to the latest TWS...
The oldest TWS I have available is 924. Does TWS 917.9 have any specific advantages over the more recent versions up to TWS 932 (e.g. TWS 924)?...
