+The Stock Options module of the OpenBB SDK wraps the functions of the Options [sub-menu](https://openbb-finance.github.io/OpenBBTerminal/terminal/stocks/options/) within the [OpenBB Terminal](https://openbb-finance.github.io/OpenBBTerminal/terminal/). This allows the user greater flexibility when researching and anlayzing options data. Start a Python script of Notebook file by importing the dependencies:
+
+```python
+from openbb_terminal.sdk import openbb
+
+import pandas as pd
+import numpy as np
+
+import matplotlib.pyplot as plt
+
+%matplotlib widget
+```
+
+## How to Use
+
+All functions within the Options module are printed with: `openbb.stocks.options`
+
+![Options Module Functions](https://user-images.githubusercontent.com/85772166/199891549-1331a65c-6251-4206-b77c-c64dfabe70f4.png "Options Module Functions")
+
+The [Unusual Options function](https://openbb-finance.github.io/OpenBBTerminal/terminal/stocks/options/unu/) returns a Tuple containing the DataFrame and a timestamp from when the list was last updated.
+
+```python
+unusual_options,timestamp = openbb.stocks.options.unu()
+unusual_options
+```
+
+![Unusual Options](https://user-images.githubusercontent.com/85772166/199891691-da3af87e-99c3-4d01-881f-62b6b0d3ae34.png "Unusual Options")
+
+Get up to ten years of historical put/call ratios (US equity options only), with the `PCR` function:
+
+```python
+pcr_spy = openbb.stocks.options.pcr(symbol = 'SPY', start_date = '2012-11-03')
+pcr_spy.rename(columns = {'PCR': 'Put/Call Ratio'})
+```
+
+![openbb.stocks.options.pcr](https://user-images.githubusercontent.com/85772166/199892365-f0ece3fa-307f-41cd-9326-d515f1d8b716.png "openbb.stocks.options.pcr")
+
+The list of expiration dates is generated with:
+
+```python
+openbb.stocks.options.option_expirations('SPY')
+```
+
+Get the raw DataFrame for an options chain from yFinance by using:
+
+```python
+SPY221111 = openbb.stocks.options.chains_yf(symbol = 'SPY', expiry = '2022-11-11')
+
+SPY221111
+```
+
+![openbb.stocks.options.chains_yf](https://user-images.githubusercontent.com/85772166/199900266-668af99d-ae72-4bca-9b40-14228b25279b.png "openbb.stocks.options.chains_yf")
+
+Getting all option chains for the underlying symbol as a single Pandas DataFrame requires a little bit of scripting prior to analysis. This will query Tradier as the data source:
+
+```python
+from openbb_terminal.sdk import openbb
+import pandas as pd
+import numpy as np
+
+expirations = openbb.stocks.options.option_expirations(symbol = 'SPY')
+options_df: pd.DataFrame = []
+
+for expirations in expirations:
+    options_df.append(openbb.stocks.options.chains(symbol = 'SPY', expiry = expirations))
+
+options_df = pd.concat(options_df)
+
+options_df.set_index(keys = 'symbol', inplace = True)
+
+options_df
+```
+
+Depending on the depth of options available, compiling the data may take upwards of thirty seconds.
