I am very glad to hear you enjoyed the courses!
To be honest with you I can not give you an exact answer, how much time you will need to follow the system from the Professional Forex trading course. This really depends on the market itself. As you will see with the trading example inside, we are waiting for the right moment to enter. Anyway it is really a professional Forex trading course, and you have much to learn from there.
If you are busy with your work on the other side, I would suggest you to stick with the algorithmic trading courses.
