When trading, one must understand that position management is more important than entry and exit points. Many people study various indicators, which is essentially just about figuring out how to enter the market; however, this is not the core of trading. Most strategies are merely about breakthroughs and finding support and resistance levels.
Many people go to great lengths to study various tactics, but it is better to consistently execute a single strategy for three months. 20% of the market trends contribute to 80% of the profits; during other times, one should learn to play dead or trade lightly.
In trading, do not pursue perfection. Ten consecutive small losses are not scary; catching one wave of trends can turn things around. The most frightening thing is fantasizing when it's time to cut losses and hesitating when it's time to hold onto profits.
