YLoader is used to download historical quotes available from several financial sites.

Some of the main features:

• downloads free historical End of Day (EOD) price data from Yahoo, Google, MSN or Quote Media
• extensible to other data providers through data source plug-ins
• GUI and console-only versions
• intuitive and easy to use user interface and commands
• fully automated runs using both the GUI and console-only version
• configurable through a rich set of command line arguments
• virtually unlimited output data formats, configurable through fixed settings or regular expressions
• multiple simultaneous connections to the data provider for fast downloads
• symbols list can include any number of symbols
• data can be requested for any available date range
• prices can be unadjusted or split and dividend adjusted  
• different bar durations: daily, weekly, monthly
• data validation,
• data file name customization
• logging of session events to file
• bonus application symbols.exe can download all most up-to-date Nasdaq, NYSE and AMEX symbols.

See the session.bat file for an example of how to create a batch file for an automated downloading session, that retrieves the most recent Amex symbols and saves them in "symbols\sym.txt, and then downloads and saves their market data in the directory "data", both under the installation directory.

The whole process can be further automated by adding a new scheduled task for this or similar batch file to the Windows Scheduler (which can be found in the Control Panel\Scheduled Tasks). This task can be programmed to run every day after the market close thus making sure that the most recent data is always available locally.
