Val:
Omega server is a DDE Server. It takes only specific commands. It honors
requests using the BIFF3 clipboard format from Excel. It also honors
requests from TradeStation, per the Omega SDK (available free from Omega
Research). TradeStation acts as a DDE client to the Server. To the best of
my knowledge, there is no way to make it act as a DDE Server except by
attaching a DLL to it that does the DDE service. This would be a lot of
work. Far simpler to use a global variable scheme such as TradeLab provides.
There's not too much that's special about writing a DLL; you need to use a
language that supports it. Generally, generating a DLL is a compiler
option. There's a free TS kit that explains the interface from the Omega side.
