2	Changing Sources	How to change which data sources are the default source for commands run in the OpenBB Terminal.	source sources default source datasources api keys api keys openbb sdk yfinance yahoo finance alphavantage polygon EODHD change the source

import HeadTitle from '@site/src/components/General/HeadTitle.tsx';

Many commands have multiple datasources attached to it. A great example is /stocka/fa/income that allows you to select FinancialModelingPrep, Polygon, AlphaVantage, EODHD or YahooFinance. Many have a default source, but you can change the default sources of each command via two methods.

Changing the Source

Returning to the example of the income command instead the stocks/fa menu. This source has multiple sources to choose from. You are able to specify this source with the --source argument. This also becomes clear from the help menu.

(🦋) /stocks/fa/ $ income -h

usage: income [-t TICKER] [-q] [-r] [-p column] [-h] [--export EXPORT] [--sheet-name SHEET_NAME [SHEET_NAME ...]] [-l LIMIT] [--source {FinancialModelingPrep,Polygon,AlphaVantage,EODHD,YahooFinance}]

Prints a complete income statement over time. This can be either quarterly or annually.

optional arguments:
  -t TICKER, --ticker TICKER
                        Ticker to analyze (default: None)
  -q, --quarter         Quarter fundamental data flag. (default: False)
  -r, --ratios          Shows percentage change of values. (default: False)
  -p column, --plot column
                        Rows to plot, comma separated. (-1 represents invalid data) (default: None)
  -h, --help            show this help message (default: False)
  --export EXPORT       Export raw data into csv, json, xlsx (default: )
  --sheet-name SHEET_NAME [SHEET_NAME ...]
                        Name of excel sheet to save data to. Only valid for .xlsx files. (default: None)
  -l LIMIT, --limit LIMIT
                        Number of entries to show in data. (default: 5)
  --source {FinancialModelingPrep,Polygon,AlphaVantage,EODHD,YahooFinance}
                        Data source to select from (default: FinancialModelingPrep)

For more information and examples, use 'about income' to access the related guide.

Within the source arguments it shows the exact sources as previously mentioned. Therefore, with this information in hand it is possible to switch to a different source e.g. with income --source Polygon. Do keep in mind that you might need to have an API key to use this source, see here.

Working with the Sources Menu

In case you are looking to change the default source al together, you can do so via the sources menu as found on the homepage of the OpenBB Terminal.

For example, if you would like to change the default data provider from the income command from the stocks/fa menu you can first run the command get --cmd stocks/fa/income. This returns the following:

(🦋) /sources/ $ get --cmd stocks/fa/income

Default   : FinancialModelingPrep
Available : FinancialModelingPrep, Polygon, AlphaVantage, EODHD, YahooFinance

Then, with set you can change the default data provider. For example, we can change the data provider to Polygon with the following:

(🦋) /sources/ $ set --cmd stocks/fa/income --source Polygon

Default data source for 'stocks/fa/income' set to 'Polygon'.

(🦋) /sources/ $ get --cmd stocks/fa/income

Default   : Polygon
Available : Polygon, FinancialModelingPrep, AlphaVantage, EODHD, YahooFinance
