Yahoo Options Data for PythonThis module retrieves option data from the yahoo finance website and
calculates greeks from it.Warning: The retrieved data and greeks might be outdated or incorrect.
Use at your own risk.InstallationYou can install the library by using:pip install yoptionsImportimport yoptions as yoDownload option chain with greeksTo download the option chain for a specific stock for the next expiration date, you can
simply use:# Chain of all FORD MOTOR COMPANY call options for next expiration date
chain = yo.get_chain_greeks(stock_ticker='F', dividend_yield=0, option_type='c', risk_free_rate=None)
print(chain.head().to_string())risk_free_rate is optional. If it is left empty, the current risk free rate from the US treasury will be retrieved
and used.This will calculate and print Delta, Gamma, Theta, Vega and Rho for every option in the chain.OUTPUT:
