Re: (Sensible) Definition of a derivative conctract's notional amount

for the Residual risk add-on you either take the gross notional amount or,  if the gross is nonexistent,  take the maximum potential loss, for the latter you have to get the Expected Effective Positive Exposure which is defined in SA-CCR as : 1.4 *( MtM +PFE(vol of underlying risk driving the contra...

What sort of maths is needed for algorithmic execution quant developer?

1-Market Intuition----> good luck with that.2-a mathematical model to mimic a very complex reality (all the mathematical tools you can fathom )3-a coding language (c# ,c++,MatLab,etc...)

SABR Risks.

we generate a vol surface using SABR ,then we apply different twists and turns to this surface to compute vega,is this correct ?should we shift parameters ,recalibrate and compute vega ? or shift the surface ?
