The original version incorporated network data acquisition from Yahoo!Finance

from `pandas_datareader`. Yahoo! changed their API and broke `pandas_datareader`.



The changes allow you to specify your own data so you're not tied into equity

data from Yahoo! finance. If you're still using equity data, just download

a CSV from finance.yahoo.com and use the `data.yahoo_data_helper` method

to form the data properly.



### Volatility estimators include: ###



* Garman Klass

* Hodges Tompkins

* Parkinson

* Rogers Satchell

* Yang Zhang

* Standard Deviation



Also includes



* Skew

* Kurtosis

* Correlation



For each of the estimators, plot:



* Probability cones

* Rolling quantiles

* Rolling extremes

* Rolling descriptive statistics

* Histogram

* Comparison against arbirary comparable

* Correlation against arbirary comparable

* Regression against arbirary comparable



Create a term sheet with all the metrics printed to a PDF.

Example usage:



```python



from volatility import volest

import yfinance as yf



# data

symbol = 'JPM'

bench = 'SPY'

estimator = 'GarmanKlass'



# estimator windows

window = 30

windows = [30, 60, 90, 120]

quantiles = [0.25, 0.75]

bins = 100

normed = True



# use the yahoo helper to correctly format data from finance.yahoo.com

jpm_price_data = yf.Ticker(symbol).history(period="5y")

jpm_price_data.symbol = symbol

spx_price_data = yf.Ticker(bench).history(period="5y")

spx_price_data.symbol = bench



# initialize class

vol = volest.VolatilityEstimator(

    price_data=jpm_price_data,

    estimator=estimator,

    bench_data=spx_price_data

)



# call plt.show() on any of the below...

_, plt = vol.cones(windows=windows, quantiles=quantiles)

_, plt = vol.rolling_quantiles(window=window, quantiles=quantiles)

_, plt = vol.rolling_extremes(window=window)

_, plt = vol.rolling_descriptives(window=window)

_, plt = vol.histogram(window=window, bins=bins, normed=normed)



_, plt = vol.benchmark_compare(window=window)

_, plt = vol.benchmark_correlation(window=window)



# ... or create a pdf term sheet with all metrics in term-sheets/

vol.term_sheet(

    window,

    windows,

    quantiles,

    bins,

    normed

)



```
