[amibroker] LogNormal Distribution in Options Pricing Model

 

Hello,

I am looking to incorporate the BlackScholes model on option pricing into some Amibroker Code.

Looking through previous posts raises some questions I was hoping for some assistance with.

BlackScholes model alternatives

  • I am aware of alternative models and was wondering if anyone had coded any of these into Amibroker?, notwithstanding the appropriateness or validity of them.

Existing Amiboker code on Black Scholes
I am aware of the existing code by;

Anthony Faragasso (2005) Black Scholes Option Pricing which seems to use a Standard Normal Distribution Function of ( x )
Vladimir Gaitanoff (2003)Option Calls, Puts and days till third friday which seems to take the same approach in terms of the distribution function.

I was wondering if anyone had progressed since then, using additional functionality subsequently available in Amibroker.

LogNormal Distribution
I am also aware of Howard Bandy's Normal Distribution function in his book and Amibroker post.

  • Is their a LogNormal distribution function in Amibroker?
  • Is their an approximation of the LogNormal distribution function that I could use.
A quick Google suggests that various methods have their limitations, although the maths is way beyond my level of understanding.

Would appreciate any support?

Regards

Paul McLaren
