Flat Files

Pro

REQUIRED

The Theta Terminal must be running to access data.

Behavior

  • Flat files are only available to pro users. The 7 most recent calendar days of data are available.
  • Data for the previous day should be available around 12:30am - 1am EST.
  • We have tentative plans to ease this limitation in the future.
  • If you are interested in procuring more than the 7 days available, contact sales@thetata.com.
  • A flat file will return the path to the file once it is complete.
  • We strongly recommend using a fast disk for where the terminal is running.
