Trading forex can be risky and it is important to approach it with caution. Over-trading, or trading too frequently, can lead to emotional and financial stress. It is important to have a well-defined trading plan and to stick to it, as well as to manage risk properly.
I learned a lot of new techniques and chart patterns. Also, this forum provides traders to communicate with other traders and learn from their experiences as well.
Indicators, chart patterns, and the study of daily market trends are also important apart from theoretical knowledge. On the other hand practice on a demo account is also necessary.
It depends on an individual trader how long he/ she wants to use it. Once a trader is confident enough and learns each perspective of trading then he/she can switch to a live account. But there is no specific fixed time for how long a demo account should be used.
