In the majority of cases, a program makes a trader's job easier,
eliminating the necessity of a constant tracking of market situations,
sitting before a computer for a long period of time.
It may also help to relieve nervous tension and to lower the number of errors appearing in periods of extreme emotional tension.
But,
the main thing is that using the program method of trade management allows traders to develop their own ideas and test them on historical data,
to select optimal parameters for applying these ideas, and finally,
to implement a thought-out trading strategy.
