anybody know a good paper or discussion on backing out FX option implied distributions from 10&25delta RR and Flys?I do it with equity index call quotes (after some interpolation considerations) using:P_implied(K,T)=exp(rT)*C''(K)My intuition suggests the same should be possible using RR and Flys for FX (perhaps even just Flys)any help appreciatedrgds
