As it was said, it's really better to start off small, because sometimes market can still be unpredictable and wreck us

Using the limits both for going onto the positions and for the trading session overall is the best course of action, in my opinion.
Agreed. And I am a champion for this. Even though the profit may not be massive, start off small - gain experience and build your account up from there. Anyone who is just a beginner do not need a large capital, you are going to blow it off. After you have built up experience then you can play around with huge capital and even more risker types of trade. Other than that, it is a very high risk gambling which I am sure the trader who is a beginner has not risk management in place if they start off with a huge trading capital.
