Option Valuation for Roll Optimised Strategies

<t>Say you have a roll optimised future roll strategy, which invest in a new future every month...The possible future range will be the entire future curve.To value an option on that strategy say in one year, this is not trivial, as you cannot know, on which future the option will expire.Even the im...

New Book: PDE Valuation of Interest Rate Derivatives

<t>QuoteOriginally posted by: CuchulainnA number of schemes have been advocated for this PDE in x and y(which has the same form as Asian PDE). It is difficult and easy at the same time, depending on how you tackle it:difficult: no diffusion in y, so 3-point centred differences give problems and are ...

Boundary conditions for pricing barrier swaptions

<t>Do not think to much of the behaviour of the swaption at your boundary points,rhather think about WHERE you choose your boundary points..Ususally assuming Gamma to be zero at the boundaries is sufficient, i.e. This results in Linear Extrapolation at the boundaries: As i said it is critical where ...

Boundary conditions for finite difference

<t>QuoteOriginally posted by: dongtaLet me follow up with a question: In numerical methods, we can only solve the equation from S_min to S_max. What do we put for the BC at S_min and S_max? Thanks.You should not think about to long what kind of boundary condition you apply - assuming gamma=0 as BC m...

New Book: PDE Valuation of Interest Rate Derivatives

<t>alright unkpath, i think we all got your point.i think it's nothing to be angry about that i decided to publish that text in book format ( duh! ) - if you think that it's not worth reading, so long - i do think it is.On the other hand, if you want to start an "open-source" finance-book publishing...

LocalVolModel: Arbitrage-Fee Intepolation on Prices

<t>Hi,to receive positive local variances with the Dupire formula, you need increasing prices in maturity direction and positive second derivatives (positive density values)..With an smoothing algorithm (cubic spline interpolation) i achieve arbitrage free prices over strikes.The problem is the inte...

Interpolation of implied vols

<t>my answer might not help very much...but i had the same problems, when reading the remark about arbitrage violations...Probably one might be able to proof some general result concerning convexity within that interpolation...this would be interesting.I am not quite sure, why you're having problems...
