Hi friends,

I delivered a talk to my team today on Options Pricing with Python. It was tremendous fun - with lots of intuitive examples, code-snippets and visuals.

I would love to share the powerpoint deck and the PDF document containing the code snippets.

Cheers!
Quasar.

@Quasar Chunawala I remember reading somewhere else on the forum that you had passed the Level II exam of the CFA Program. Did you ever go on to sit and complete Level III? Just recently passed Level II, signing up for Level III in June 2018 in the coming weeks.

Your python code doesn't look really Pythonic. It looks more like you are coding in C++ or Java instead of Python.

For example, your initialization of the C ndarray could be done better this way:
Code:
if optionType == 'C':
    C[N] = np.where(S[N] > strike, S[N]-strike, 0)
else:
    C[N] = np.where(strike > S[N], strike-S[N], 0)
or if you want to take it to the next level:
Code:
C[N] = np.where(S[N] > strike, S[N]-strike, 0) if optionType == 'C' else np.where(strike > S[N], strike-S[N], 0)
In Scientific Python, you tried to avoid loops as much as possible. That's the power of the language.

Hi, I tried using the code as you wrote it and keep getting a math domain error.

sigma = sigma2 + (-sigma2 + math.sqrt(sigma2*2 + d1d2 *(2sigma2*P+Q)))/(d1d2) -> causes the issue as the "P" component is negative under the square root. I am probably missing something. Any help would be appreciated. Thanks.
