In the K线, there are various forms of long positions trend, below are some common forms.

1. After the moving averages congeal, they diverge upwards: During a sideways adjustment, the short, medium, and long moving averages intertwine and congeal together. Then, they suddenly break out of the congealed state, diverging upwards and gradually forming a long positions arrangement. The longer the congeal time, the greater the strength of the upward divergence.

2. Silver Valley: Formed by the intersection of three moving averages, the short-term moving average crosses above the medium- and long-term moving averages from below, and the medium-term moving average crosses above the long-term moving average from below, forming an irregular triangle with a pointed upward direction. It indicates that the bulls have gathered considerable upward momentum.

3. The dragon emerges from the sea: When the price is sluggish, a large bullish candlestick suddenly appears, engulfing several short, medium, and long moving averages, and the closing price is above multiple moving averages, like a dragon leaping out of the sea, indicating the return of long positions.

4. Inverse Head and Shoulders: Composed of the left shoulder, head, right shoulder, and neckline. When the right shoulder forms and the price breaks through the neckline, it is a buying opportunity. Typically, a surge in trading volume is required when the neckline is broken.

5. W bottom: Also known as a double bottom, it has two identical or similar bottom points. When the price breaks above the neckline, it may signal an upward movement. The farther apart the two bottoms are, the greater the likelihood of a future reversal, and the larger the potential fluctuations.

6. Arc Bottom: The arc phase is usually a period when large institutions accumulate positions. After the pattern is completed, a significant rise typically follows. During the formation of the arc, trading volume is generally high at both ends and low in the middle. The longer the formation time, the stronger the reversal will be in the future.

7. V-shape: The V-shape reversal appears rather suddenly, and the trading volume generally increases significantly during the reversal, with the market quickly shifting from a downtrend to an uptrend.

8. Old Duck Head: Formed by multiple moving averages, the 5-day and 10-day moving averages cross above the 60-day moving average to form the duck neck, the price falls back to form the duck head top, after the 5-day and 10-day moving averages form a death cross and then a golden cross to form the duck nostrils, the duck's mouth opens (price exceeds the duck head top) indicating that an upward trend will begin.
