Dear all,
Please see this: http://www.mathworks.com/matlabcentral/fileexchange/29434-connecting-to-interactive-brokers-via-activex-api
The code is working perfectly, I am just wondering at this part of the code
%%now create an event listener and start displaying data
l = CListener('SPY');
l.startListening(tws,'trade');
How do you store this information in the array whilst its listening?
Best,
M

Aspen is probably empty. Creation of an ActiveX client probably failed.
