openbb_platform/providers/finviz/README.md
This extension integrates the Finviz data provider into the OpenBB Platform.
It will install, finvizfinance, to power the functions.
To install the extension:
pip install openbb-finviz
The screener is a faithful replication of the public-facing stock screener - https://finviz.com/screener.ashx?
Some options are directly accessible through the function parameters, all others are exposed via presets or filters_dict.
The filters list below are exposed in the function, with choices visible in the docstring:
exchangeindexsectorindustrymktcaprecommendation (analyst's mean score from 1-5)signal (same as the "Signal" on the Finviz page)When the function is run without any parameters, it will default to the "top_gainers" signal.
res = obb.equity.screener(provider="finviz")
The metric parameter defines the type of data fields to return. Choices are:
overviewownershipperformancetechnicalvaluationDefault is, "overview".
res = obb.equity.screener(provider="finviz", metric="performance")
Presets can be created and customized in the "OpenBBUserData" folder. Template and default presets are created on the first run of the function.
Files are loaded on runtime, changes are effective without restarting the Python interpreter.
The preset parameter will override all others, except metric and limit.
Run the function to create the template and default presets in your OpenBBUserData folder.
Presets from the legacy OpenBB Terminal will continue to work, simply move your presets into the folder below.
res = obb.equity.screener(provider="finviz", index="nasdaq")
Then find the presets here: $HOME/OpenBBUserData/presets/finviz
res = obb.equity.screener(provider="finviz", preset="short_squeeze")
The filters_dict parameter acts as an alternative to preset, accepting a dictionary or JSON encoded string.
res = obb.equity.screener(provider="finviz", filters_dict={"Index": "NASDAQ 100"})
Or as a JSON:
res = obb.equity.screener(provider="finviz", filters_dict='{"Index": "NASDAQ 100"}')
When using the Fast API, this is sent in the request body.
All parameters are validated, incorrect keys and choices will raise an error with information to help correct. For example:
obb.equity.screener(provider="finviz", filters_dict='{"Index": "NASDAQ"}')
Invalid filter option 'NASDAQ'. Possible filter options: ['Any', 'S&P 500', 'NASDAQ 100', 'DJIA', 'RUSSELL 2000']
