As for me, every trader should have a comprehensive approach to trading. I realized the importance of this approach through my own mistakes, and this understanding became one of the key moments of my formation as a trader.
So, what is the comprehensive approach to trading? Initially, the comprehensive approach implies a wider view of the trading process than most non-professional amateur traders see it. Many, having read technical analysis works, look on the price chart, trying to see the characteristic figures or divergence of price and indicator. Other traders giving preference to the fundamental analysis wait for release of important financial news, and then try to connect with them current, and to predict the future price movement on their basis.
The danger of this one-sided approach is that if a person is looking for certain signs (whether they are technical analysis figures or the relative position of stars in the sky), he will definitely find them (and even where they aren't actually there).
You don't have to try to embrace the infinite, I'm only saying that before making a decision you should look at the question from several angles, it will always help to clarify the situation and as a result - to protect you from mistakes.
