The most important basic knowledge of trading, technical analysis and fundamentals, If a trade is made without analysis they are only guessing by their feelings, not by reading the charts and how the fundamentals occur.
If you don't have basic knowledge, then don't trade, it will only cause losses because you don't know when to enter and when to exit.
Not only that, management also needs to be done to make trades according to the strategy and not make trading a waste of money.
