comment Heuristics for calculating theoretical probabilities of being ITM at time T for listed options
@ Dragan Chupacabric : By probability you mean risk-neutral Probability (associated to stock-numéraire), right ? This is not comlpetely clear from your question when you say "I use delta as a proxy for this probability of success for single options". Regards

comment How do practitioners use the Malliavin calculus (if at all)?
I don't like this answer and vote it down. Moreover, I don't agree with the idea that there is an antagony between academics and practitioners.

you can still use very short maturities (listed) Libor Options Implied Vols if you want to, but as for such maturities vol isn't really the issue you can use flat first caplet vol instead. Regards

comment Rate interpolation in Libor Market Model
Well I haven't implemented the paper but argument seems fine even if the solution to make the fixed Libor is a little "articial" in my opinion and the author could have reformulated it in a more natural way within the framework of Schlögl with "a model" for short rates. Regards.

comment Rate interpolation in Libor Market Model
As this article is quite recent, I haven't read it. I'll take a look and tell you what I think about it. Anyway, there is also some interesting material about this topic in books of Brigo and Mercurio and in the book(s) by Andersen and Piterbarg. Regards

@Shane : Ok I agree with you and I will post an example of the prototypical answer I am targeting (at least I'll try), but simply I don't have the time to do it right now, so a little patience is in order here ;-) Regards
