  Optimal structure of proteins is described by linear stochastic differential
equation with mean decrease of free energy and volatility. Structure
determining strategy is given by a twin of stochastic variables for which
empirical conditions are not postulated. Optimal structure determination will
be deformed to be adoptive to trading strategy employing martingale property
where stochastic integral w.r.t. analytical solution of stochastic differential
equation will be employed.
