error Code: 420 | Invalid Real-Time Query in reqRealTimeBarsEx (AEX +CAC) I'm using the VB.net sample program (using TWS ActiveX control) to test some code. When I use Symbol GOOG, everthing is working (Req Mkt Data / Hist.Data / RTbars) I'm using SMART as Exchange. When I use a Dutch (AEX) Symbol or France (CAC) I get an error? So I use : Symbol=ING / Exchange=AEB / Currency=EUR The req. Mkt Data and Hist. Data are working, BUT the RTbars give me the following error : id: 29622819|Error Code: 420|Error Msg: Invalid Real-time Query. Anybody an idea ?? Kind regards, Michael
