Is technical analysis useful?

A complete trading system includes opening and closing rules + capital management. The core of trading lies in capital management, not in opening and closing. Don't spend too much time learning techniques; the real core of trading lies outside the candlestick charts, such as your mindset, emotions, execution ability, and so on.

The ancestor of trading speculation, Livermore, what techniques did he have? In his time, there were no candlestick charts; there were no monitors invented yet. Stock prices were sent over by telegraph and then written down on a blackboard.

Livermore only knew one move: breakthrough, chase! (Similar to Fatty, making breakthroughs)

The trading field requires someone to guide you in; if no one points it out for you, many people will never get out in their lifetime. Many people have spent many years in the trading market, going around in circles, always learning techniques. After learning the theory of cycles, they still lose money; they continue to learn about waves, and after learning about waves, they still lose money, looking for various indicators to study. In the end, after all the learning, their hair has turned white, and they still can't make it work, resulting in losses. For example, a simple opening and closing rule: open long on a strong volume long bar, open short on a strong volume long bar, if wrong, stop loss; if right, move the take profit. Just doing this one rule that you can understand is enough to make you money. We only need to find a technique to learn, then rely on our own experience accumulation to refine some high win-rate opening and closing rules for our own use, and not learn so many random things.

Many people are talking about various indicators. Can indicators really predict future trends? What indicators should we learn?

Indicators do not predict future trends; indicators come from a series of calculations based on prices. First, there are prices, then there are indicators. Why can it predict future trends? Indicators are just a quantification and visualization of price trends and cannot predict future movements. The correct way to use indicators should be to find patterns. You only need to select one indicator and then find the relationship between this indicator and the price. Those colorful indicators on the screen are either meant to deceive you or are half-baked.
