In the theory of K-line combination, most K-line combination forms are composed of different single-day K-lines through various permutations and combinations, but some K-line combination forms are composed of K-lines and different technical analysis. Among them, the K-line combination forms formed by the combination of K-line and EMA system mainly include: lotus coming out of the water, rising sun, breaking hay cutter, setting sun, breaking through the tight encirclement and ambushing on all sides.

"Water Lotus" K line and "Rising Sun" K line are breakthroughs in different moving averages. The former refers to breaking the short-term moving average (20, 40, 60-day moving average), while the latter refers to breaking the long-term moving average (240-250-day moving average), while the "breaking" K line refers to breaking all the long-term and short-term moving averages, and the turning signal of this K line is more obvious.

Technical features:

1. The "tight encirclement" K line means that a K line breaks through the 10 moving average at the same time, including 5th, 10, 20th, 30th, 40th, 60th, 90th,120th and 65438. The opening price of "tight encirclement" K line is less than 10 moving average, and the closing price is greater than 10 moving average;

2. The volume of "tight encirclement" K-line has been enlarged;

3. The "tight encirclement" K line makes some moving averages turn.
