I saw the same behavior with .dly files; premarket daily bars update on the chart, but the .dly files on disk don't reflect the changes until later.

Daily files are very different - these do not update until the end of the trading day. These do not update otherwise.


Is there a setting that controls how frequently Sierra Chart writes streaming data to .scid files on disk?

Yes - refer to the following:
Advanced Service Settings: Intraday File Flush Time in Milliseconds (Global Settings >> Advanced Service Settings >> Other)

You can not get access to the real-time data in real-time. It is not allowed by the exchanges, so there is always going to be some delay.
For the most reliable, advanced, and zero cost futures order routing, use the Teton service:
