Perhaps you are sending the request to the Level1 port instead of to the Lookup port.

Are you sending S,SET PROTOCOL first? The Market Summary commands were only added in Protocol 6.1, so if you're not specifying 6.1 or 6.2 the API will not recognize this command.

Also (as altmany just said) make sure you are connecting to Port 9100. Other ports (like 9400) will not understand this command.



Sincerely,
