Application Configuration File

Application Configuration File

The application reads settings from the application configuration file.

The default file is market.csv.exe.config. Please always keep it with the executable file, market.csv.exe.

You may specify alternative files using the config option. For example:

market.csv.exe download YahooFinanceQuotes symbols\uk-symbols.txt /config=configs\uk.config

This feature is used for loading different settings for different markets.
