What is DTN Market Access (DTNMA) and why do I need it?
Investor/RT users who use a brokerage feed to supply data to IRT have often found that the historical back fill provided from their brokerage feed is unreliable, incomplete, or insufficient. These feeds include Interactive Brokers, TransAct/Infinity, and Rithmic. Interactive Brokers users should read the article located here to learn more about how IB's data differs from true tick data.
These users have a fast, reliable, and comprehensive back fill alternative with DTN Market Access Historical Service (DTN MA). When your license includes DTN MA, all historical back fill requests will be routed to DTN historical servers instead of your broker. Your real time data still comes from your broker. Almost all of our brokerage data source using clients use DTN MA to back fill their charts.
How much is DTNMA /Who supports it/How do I turn it on?
DTNMA is priced at $15.00/month and is licensed directly by Linn Software.To add DTN MA to your license, open Investor/RT and go to File->License->Revise License.
What is a Symbol alias and how do I set one up in Investor/RT?
A symbol alias is a way to communicate to Investor/RT that you get your data from two different places. If you are getting real time data from your brokerage and historical data from DTNMA, you will need to set up an alias for each symbol you are tracking. To set up an alias, go Setup>Instruments (or click Ctrl A). Enter your brokers symbol in the Instrument field and the DTN MA symbol in the alias field as shown below. For a complete list of all symbols, view the symbol guide using the Tabs on this page.
