How do I import external historical data from a text or csv file?
The Import Window is accessible via the Data menu. Investor/RT supports importing of daily, weekly, monthly, or intra-day data.When importing historical data you must specify via the Import Format menu, how the data in the input file is arranged. When the desired format is not one of the formats available in the menu, go to File > Preferences > QuotePage > QuotePage Formats to create a format that lists the incoming data fields in order. The newly format name will then be available for selection in the Data > Import window.
