Following up someone else trading signal as a newbie trader is not always advisable because when you keep following that person in form of copy trade whenever such person make seriously makes it surely affects you that is following up the person. What do you do then is better to develop yourself and have your personal trading guides and techniques for a better trading experience, for instance you can learn from various people and create your own methods that could suits you more better than following up others on how they trading.
Anything fun to learn by yourself should not be copied from someone else and the same is true in trading. If you find a good expert who you are copying. If the signals all sound right and he is a successful trader, then you can make a good profit, but if you are following someone who is self-destructive or who does not understand the market very well, you lose a good amount of money.
It is also worth noting that when we are copying someone else, we are not learning anything from ourselves, our minds become dependent on others, and the ability to think for ourselves is not enough. Our self-confidence also decreases, so a person should learn and trade by himself.
This is the reason why I'm against copy-trading.
