This presentation builds further on the work contained in [1]. We discuss again the meaning of a q derivative [2][3] and interpret the value of q in a financial environment. We are particularly interested in this presentation to discuss how the stochastics are affected when we use such derivatives. In particular, why is the Ito lemma (see [4] for instance) not usable? We also expand on the use of this type of derivative in finance.
