Hi John, thanks for the clarification.

Just a suggestion for the Sierra Chart team — the documentation on the DTC Protocol could really benefit from a clearer disclaimer that real-time outbound market data (like MarketDepthUpdateLevel) is no longer transmitted via DTC due to exchange restrictions.

Right now, the way it’s presented on the website and in developer materials still implies that full DOM/tick data is accessible through the DTC Protocol, which can easily mislead developers into building full architectures around it — only to hit a wall, as I just did.

It’s clear Sierra still supports the infrastructure, and that’s appreciated, but many of us rely on clear up-to-date technical documentation when designing data pipelines. A small update there would save others from wasting time, energy, and possibly money.

Thanks again for confirming — we’ll pivot accordingly.
