Possible Error in Code

Course Name: Options Volatility Trading: Concepts and Strategies, Section No: 16, Unit No: 18, Unit type: Notebook

Hi, I'm checking the mathematics within the Jupyter notebook and I think that you are using the parkinson estimator incorrectly - it is square rooted and so is NOT a variance number in this example.

 

Hi Alun,

We will check this and get back to you. 

Hi Alun, the code has been updated by using the square of the Parkinson estimate for variance.
