 * @brief Theo price

 * dxPrice model-free computation. It represents the most recent information that is available about the corresponding
 * values at any given moment of time. The values include first and second order derivative of the price curve by
 * price, so that the real-time theoretical option price can be estimated on real-time changes of the underlying price
 * in the vicinity.
