Post From: DTC Server not sending MarketDataUpdateTrade messages to external client

I have the DTC Protocol Server enabled and listening on port 11099. I can successfully connect from an external Python client and send a MARKET_DATA_REQUEST (type 100) for MESM25-CME. The server responds with a successful TCP connection, but no Market Data messages are sent. Even recv(2) returns nothing — not even the header. I’ve confirmed: DTC Server is set to “Allow Trading” and “Local Computer Only” The symbol is receiving real-time data inside SierraChart (charts and Time & Sales both working) Using sub_type_flags = 7 to request trade/bid/ask/market status updates Question: Under what conditions will Sierra Chart not send Market Data via the DTC Protocol Server, even when real-time data is active? Is there any additional setting or limitation that prevents external DTC clients from receiving MarketDataUpdate messages? |
