Excel DDE with IB's TWS API problem

Discussion in 'Automated Trading' started by fostercool77, Jan 8, 2012.

  1. I inserted a new module with my own VBA in the sample application. When I start my VBA, the market data stopped updating. But it updates again after I stop my VBA. Anyone has idea what is going on? Is it an Excel setting problem?

    Thanks very much.
