Some brokers feed real time data at a price level that is different from the back fill data received from DTNMA. For instance, the Euro contract from some broker feeds, is fed in with a display format of XXX.XX but when back filled from DTN MA, its format is X.XXXX. To correct this, we can add a multiplier to the DTN Symbol alias as shown below. Just go to Setup → Instruments:
Investor/RT's automatic backfill is designed to keep daily and intra-day historical data up to date automatically without user involvement. Generally speaking, if you track fewer than 100 symbols, all historical data management should simply be done for you; there should not be a need to manually perform data downloading operations. Users who track many hundreds or thousands of symbols are exceptional cases where a higher degree of user involvement is required to keep your historical data current.
To view as text, select the Profile Indicator by clicking on the containing rectangle (of the right-most profile). If you don't see the volume at price data when selected, you'll need to zoom in vertically using the shift-scroll wheel. When zoomed to a level where there is space for the text, the text should appear.
To export the volume at price data, right click on the containing rectangle of the profile and choose "Export Data".
Investor/RT has long featured automated backfill at startup, designed to backfill historical data since the date/time that the data feed was last stopped. Starting with version 11.2, backfill is now automatic and has been enhanced to fill in any historical data per symbol for all trading that has occurred since the last trade recorded in the local database. In prior releases, Setup: Preferences: Backfill allowed user control on whether to auto backill or not and whether to auto backfill all intra-day symbols or just those open in charts.
