I'm just now figuring out how to use DDE Socket Bridge after using the Legacy DDE for the past several years. Running runDdeSocketBridge.bat (which is required to connect the API) prompts this popup that has to be accepted: Is there any way to auto-accept that popup prompt? I automate TWS through IBC and this kind of puts a wrench in everything.
You probably want to hide your account number, though I don't know if anyone can do anything with it.
