I'm unable to use TWS because of a corporate firewall. There is no way that port 4000 will be opened. I just opened the account but may have to close it if I don't have an alternative. I am a programmer and was thinking about writing a web based TWS that I could access through another computer outside of the firewall but I read in the documentation that there will be a prompt displayed anytime there is an option trade. What's more, I haven't found a way to disable the "Accept incoming connection?" prompt either. These facts render the API useless to me. So my question is, has anyone else been successful in dealing with this problem? Is there a web based system out there that gets around these issues? Any help is appreciated. I really don't want to give the money back to Datek. Thanks.
