Hello, I am trying to write a client to use the SC Relay Server functionality to stream data relayed from SC and do some calculations. But I am stuck at the very first step, which is to get ENCODING_REQUEST. Q1: I am trying to understand the procedure used by SC. For example, SC documentation stated that if the client (my script) and the server (SC itself) use the same encoding, I can bypass this step. But how do I know which encoding scheme is SC using? Do I have to send an ENCODING_REQUEST to find out or there's some documentation that I didn't find out about? Q2: As for LOGON_REQUEST, what do I use in the username/password fields? Do I use the username/password for login to SC or something else? Here's how I am packing my requests with Python struct library: format_string = '<HHI32s32s128sIII32s32s32sI'
logon_request = struct.pack( format_string, 0, # Size will be calculated after packing message_type, protocol_version, username, password, general_text_data, integer_1, integer_2, heartbeat_interval, trade_account, hardware_identifier, client_name, market_data_transmission_interval ) That's all I have for now. Without the two steps above I can't even get SC to acknowledge my client as a valid one. Here's what I got from SC: 2024-05-02 08:38:19.356 | DTC client #5. 127.0.0.1 | Received unknown message type from client. Type = 0
