Linn Software Partners - DTN Market Access

DTN Market Access is a backfill / historical service provided by DTN. DTNMA does not provide live/streaming data. If you're looking for the real-time streaming data service provided by DTN, that is DTN IQFeed. DTNMA is not needed if you're using IQFeed for live data as the backfill comes with the IQFeed service.

Intraday Historical: 120 calendar days of tick (includes pre-post market) and years of 1-Minute interval data (Forex back to Feb 2005, E-minis back to Sept. 2005, Stock/Futures/Indexes back to May 2007) retrieval for charting and time & sales data
Daily Historical: 15+ years
Internet-Based Historical Service (Windows and Mac OX are Supported)

DTN Market Access Historical Data accounts are available directly from Linn Software for $15/mo. This historical market data service can be used in conjunction with both the DTN Satellite, opentick, and Interactive Brokers Real-Time versions of Investor/RT to provide on demand backfill of charts with daily, weekly, monthly, intra-day bar and tick data. You can use DTN Market Access as your primary data source or use it in conjunction with a real-time data source. DTNMA is strongly recommended for both IB and opentick users, as a faster, more reliable, and more robust alternative for historical backfill.

For users of the Interactive Brokers or opentick versions of Investor/RT, DTN Market Access historical service can be used as an optional feature to supplement the limited historical backfill available directly from the those feeds. When you have this service enabled your Investor/RT registration code will have both an data feed id and a DTN Market Access id, e.g. U123456/LIN357 (for IB). Investor/RT chart windows automatically access the DTN Market Access servers to backfill daily, weekly, monthly, minute interval, and tick data charts. Intra-day historical data for the preceding 120 calendar days is available from any Investor/RT chart, or from the Data Download window.
