This dialog is available in the Advisor version from the File / Import / Prices / Schwab... menu command.
Select the file you wish to import pricing data from. Pricing, transaction, security, and position data files can be generated from Schwab Data Delivery. Pricing data is contained in either CRSccyymmdd.SEC or CSmmddyy.PRI files. The .SEC are the newer "B/D Core File" format, and the .PRI files are from the legacy Schwab format. Fund Manager supports importing from either file format.
All open investments will be updated. Pricing updates are done based on matching the symbol recorded for each investment with the symbol provided in the import file.
