How to experience the rhythm of the rise and fall of the market?

We all know that whether it is a strong one-sided trend market, or an oscillating upward or downward situation, the market is always up and down. So how can we control this rhythm? The combination of life line (12-day average line) and the Bollinger band can be a good solution to the problem: during the process of ajustment to strong unilateral trend market, the life line comes or very close to the candle bar, which has a high probability of rising again; when the market shows oscillating upward or downward, the backing of candle bar to the middle rail of the Bollinger band is much more likely to start a new round of upward.
