Data provider settings define periods of refreshing data, refresh intervals, and auth providers.
You may use Data Provider Manager to configure provider settings.
Also, you may change data provider settings directly in the provider configuration files, like YahooFinanceQuotes.dll.config, in the DataProviders subdirectory.
The default installation folder is %ProgramFiles%\Gartle\RealTimeToExcel.
Yahoo! Finance Data Provider Settings
See Yahoo! Query Language at https://developer.yahoo.com/yql/ to learn usage limits before the changes.
In short, this is 1000 calls per hour. Note that all Yahoo! Finance data providers connect to the single Yahoo! web service.
So, if you use two data providers, you must divide 1000 calls by two to get the available watched stock number.
For example, you watch stocks using 2 data providers. You can watch 1000 / 2 = 500 stocks with the one-hour refresh interval.
If you want to refresh the data twice an hour, divide the number by 2. In this example, your limit is 250 stocks.
The FAQ also contains the recommended limit as 0.2 calls per second. But, one call per second is quite good when the 1000 calls per hour limit are kept.
