I think people will understand it better from direct practice. because trading theory is very broad and will never end no matter how it is studied. One person simply sticks to one trading style until he is truly consistent in producing results. This is the best way to get to know these two methods of analysis.
Practicing what we understand in trading will make us have more experience in the trading we do and we can also increase our knowledge about trading so that we can gain profits from trading, when we consistently do what we understand well. Well, of course we will be able to make a profit from the trading we do.
