The big yinxian line, also known as the long yinxian line, is a stock trading term, which is characterized by almost opening at the highest price and closing at the lowest price that day. It means that many parties are losing ground under the attack of the empty side and there is no defense.

Under the price limit system, the largest daily yinxian entity in China stock market can reach 20% of the opening price of the day, that is, the daily limit opens and closes.

The strength of the negative line is directly proportional to the length of its entity, that is, the longer the negative line entity is, the greater the strength is, and vice versa. The appearance of the big yinxian is an ominous omen for many parties.

Extended data:

Generally speaking, the big yinxian has the following three functions:

1. Confirm the upper gear pressure with the big yinxian: The big yinxian may be opened by the horizontal or downward pressure line or the blocking moving average, which confirms the upper gear price pressure, and then forms the top big yinxian.

2. Break through the lower support with the big Yinxian: The big Yinxian can also break through the horizontal or upward support line or the supporting moving average in the form of a gap, thus forming a breakthrough through the big Yinxian;

3. Take the big Yinxian line itself as the pressure: the midpoint or the highest price of the big Yinxian line can be used as the upward pressure of the price rebound that occurs later. If the big negative line or some bearish K-line combination appears again here, the pressure is effective.
