## Trading task in classic mechanics

In physics, action is an attribute of system dynamics. By definition it is a functional over trajectory or history of the system:

where L is the Lagrangian. The real beauty of such description lies in developed and well studied mechanism of equation solutions.

## Quantum Mechanics and Market Observables

Quantum mechanics has quite powerful notion of observables. They are just properties of system state that can be determined by measurement process. Let’s recall main principles of quantum mechanics and how they could be applied to markets.
