Before revision:  We introduce a general class of Value\&Risk (V\&R) measures as a function of (p,X,\mathbb{P), where p is the observed initial value of X or is assigned by \pi _{P}(X) under the probability P. } Our approach is inspired by a new interpretation of the quasiconvex duality in a Knightian setting, where a family of probability measures replaces the single reference probability and is then applied to value financial positions.
