Jason Posted September 30, 2023 Report Share Posted September 30, 2023 (edited) Just went to load MT with the charts in the layout preloaded with symbols from yesterday's session and received this error. Have never seen this before and didn't do any system or software updates between runs. If I select Ignore the program is unusable. Tried system shutdown/restart and received the same error. Also encountered the same problem when loading a fresh instance of my layout. The message I receive from MT is: Medved Trader encountered an Error Symbol cannot be null or empty Parameter name: sym Please contact Medved Trader technical support and provide the error details AppVer: 1.1.9930.100 Err.Flags: Log, ShowIndicator, ShowToUser System.ArgumentNullException: at MT.MTSymbol..ctor(String symbol) in [ROOT]\MTShared\MTSymbol.cs:line 82 at MT.Trading.TradePositionsUC._populateRows(List`1 symbolList, Nullable`1 newSubtotalPosition) in [ROOT]\MT\Trading\TradePositionsUC.cs:line 1098 I will attempt to attach an image of the windows error dialog.

Jerry Medved Posted September 30, 2023 Report Share Posted September 30, 2023 can you send me the log? Quote Link to comment Share on other sites More sharing options...
Jason Posted September 30, 2023 Author Report Share Posted September 30, 2023 (edited) Okay, didn't think of this before posting but I tried disconnecting from IB Gateway, closing MT and reloading it. Everything reloaded fine. Subsequently reconnecting to IB with MT already loaded didn't seem to present any problems with functionality but when I tried shutting down MT while still connected to IB and reloading MT again received the same error. It hadn't occurred to me that the IB connection could be spawning the error. Will send log. Edited September 30, 2023 by Jason Quote Link to comment Share on other sites More sharing options...

Jason Posted September 30, 2023 Author Report Share Posted September 30, 2023 Okay, I've tried closing MT again and restarting both the IB connection and MT and can no longer reproduce the issue. Can't explain this. I know it's possible to get a very rare and benign exception error but reported this after I was able to reproduce it earlier. Nothing had changed regarding the connection on IB Gateway either. Status was green across all IB connections both now and when I was able to reproduce the error earlier.

Jerry Medved Posted September 30, 2023 Report Share Posted September 30, 2023 the issue is due to some odd position that MT is not recognizing. I will need to fix the handling. What is IBCID198163396? Quote Link to comment Share on other sites More sharing options...
Jason Posted September 30, 2023 Author Report Share Posted September 30, 2023 Good question. First time I've ever seen it. Will have to log into the IB website to investigate. Quote Link to comment Share on other sites More sharing options...
Jason Posted September 30, 2023 Author Report Share Posted September 30, 2023 That is taking the place of ARR in the portfolio. It appears to be an Interactive Brokers bond identification number. It also appears that ARR went bye-bye. Can't even pull a chart from the IB website and don't immediately see any news that would explain what's happened. But I wonder if it may have something to do with maintenance that IB is performing as it usually does on Saturday. Quote Link to comment Share on other sites More sharing options...
Jason Posted October 1, 2023 Author Report Share Posted October 1, 2023 FYI, I've found that this error hasn't just disappeared. It's thrown again when I access the my current positions. I suspect it's when balance/account updates are receive by MT. Quote Link to comment Share on other sites More sharing options...
