Stock Prophet is designed to be ergonomically efficient and allow the user to gain the most market insight with a minimum expenditure of time and effort. This is especially important in the development of neural network trading systems where large training data files must be generated reliably. Maximum reliability is achieved by minimizing the number of decisions and keystrokes required of the user. The result is a process which is easier, faster, and more reliable than the spread sheet approach normally used to build neural network data files. With practice, a typical indicator can be generated in minutes.
