For me, a newbie should start trading by studying, observing and looking for every possible outcomes. By doing so, a newbie will be able to learn first the cycle on how it will work and also, will learn on what to do.
Start with the theory then learn by practicing it with the actual amount.
As a newbie, you do not need to be aggressive, you have all the time to develop yourself so you have to start with a small amount of money
and when you learn enough that you consider yourself good already, that is the time to start risking a big amount.
Practice makes man perfect. 1st learn the basic needs in trading later invest a small amount and start trading. studying more about trading will not teach you how to trade. real experience will teach you what all issues you will face in trading. you are right after getting confidence in you then you can try to invest more amount and more profit.
