If you're using Investor/RT with DTNMA (either alone, or in
conjunction with live data from a brokerage feed), then you will likely
have a set of symbols that you'd like to backfill data on periodically.
The best way to do this, is to create a quotepage which contains this
list of symbols, and then download the data periodically, either
manually from the Download Data window, or automatically on a schedule.
This might especially be true for Indices or Statistics (like VIX.XO,
TICK.Z) that DTNMA provides backfill on but the broker feeds don't
support live.
- Create a new quotepage by choosing "File: New: Quotepage" from the
main menu.
- Enter the desired symbols into the quotepage, hitting Enter after
each one is entered.
- Save the quotepage with "File: Save: Save As" and give it a
name like "DTNMA Symbols".
- Manual Backfill: Now you can manually backfill these
symbols by clicking on the Download Data button in the main toolbar,
selecting the proper quotepage name on the left, and choosing the
periodicity and period on the right.
- Automatic Backfill via Schedule: You can also create a
schedule to automatically backfill the symbols periodically. Go
to "Setup: Schedules", and create a new schedule that has an action of
"Download Historical Data". Within the schedule, you can
specify the frequency of the backfill. Within the Action, you
may also specify the quotepage, periodicity, period, and server/source
(DTNMA). For more info on schedules, click
