Seemingly contradictory but actually unified viewpoints, is technical analysis really useful? Why did the moving average system that was used so smoothly before fail to hold up in the past two days?

Each stage has its own differences, and each target has its own differences. This is why subjective traders have not been eliminated by machine quantification and can still survive in the market. It is not that you have formulated a plan to open an order when you encounter a certain moving average, and to gamble when you hit a certain channel line. You can do a big job by resonance of key positions + indicators + trend lines + Fibonacci + golden crosses and dead crosses + overbought and oversold + divergences, etc. Although machines can dilute emotions and maintain a unified standard. But they are often limited.

Subjective traders can better adjust their current strategies. When is it most appropriate to use a certain set of things, and when is it most appropriate not to use a certain set of things? This is the reason why I often say "teaching students in accordance with their aptitude". #BTC☀ $BTC
