2 minutes to explain whether candlestick analysis is a superstition:

Candlestick: It's like watching an athlete run. You can directly see how big their strides are (whether it's a large bullish candle or small steps).

Indicators (MACD/RSI, etc.): It's like the heart rate monitor worn by the athlete. It can only tell you: "Dude, your heart rate is too fast right now (overbought)" or "You're out of stamina."

Trading theories (Chande theory, Elliott waves, etc.): It's like the athlete's MBTI; they study this person's personality and habits.
