What do “Catch up automatically” and “Tuner trades only” do on the station?

Question

Accepted Answer

Live tape recording always runs; these checkboxes do not turn it on. “Catch up automatically” at station start-up and once an hour finds trades without tape (closed before the station was installed, while it was switched off, or gaps in the recording) and fetches them from the exchange for as long as the exchange provides them. “Tuner trades only” does not fetch trades closed before the core began writing times in milliseconds (around mid-September 2026), and it erases their tape. If “Record emulator trades” is turned off, the emulator tape is erased. “Keep tape” limits the storage period.
