金禅子：趋势线在实盘交易中如何运用

Taking advantage of the situation is a traditional operational concept and the core content of various trading theories advocated by trading masters both domestically and internationally from ancient times to the present. In the technical indicators for tracking trends, there areBOLL通道、均线理论、停损指标、趋势线等。趋势线作为其中的一种，在分析趋势行情中有着自己的特点，投资者不但可以利用趋势线跟踪把握趋势，更可以找到行情的转折点。下面笔者结合自己多年的实战经验就趋势线在futures中的应用作一简要分析。

1、 General application of trend lines

The so-called trend line is a straight line formed by connecting the low and low points of fluctuating market prices or connecting the high and high points. There are three types of trend lines: upward trend line, downward trend line, and oscillatory trend line. There are two types of upward trend lines: upward pressure line and upward support line. If the high and low points of the market gradually move upwards during the development process, connecting the high and high points forms an upward pressure line, and connecting the low and low points forms an upward support line. The trading strategy for the upward trend line is:

Firstly, in market fluctuations, when the market is in an upward trend and the price has rebounded to the upward support line, multiple orders can be intervened and a break below the trend line can be used as the stop loss point for multiple orders.

Secondly, during market fluctuations, when the market is in an upward trend and the price reaches the upward pressure line, multiple positions can be closed and sold without selling, waiting for another buying transaction.

　　下降趋势线分下降压力线和下降支撑线两种。如果行情在发展过程中高低点逐渐下移，将高点和高点之间连接就形成了下降压力线，将低点和低点之间连接起来就形成了下降支撑线。下降趋势线的交易策略是：

Firstly, in market fluctuations, when the market is in a downward trend and the price has retreated to the downward pressure line, short orders can be sold and the stop loss point for short orders can be set to rise or fall below the downward trend line.

Secondly, during market fluctuations, when the market is in a downward trend and the price drops to the downward support line, short orders can be closed and sold, without buying and waiting for another sell.

The oscillation trend line is divided into two types: oscillation pressure line and oscillation support line. In an oscillating market, connecting high points to high points forms an oscillating pressure line, while connecting low points to low points forms an oscillating support line. The trading strategy for oscillating trend lines is:

Firstly, in an oscillatory market, when the price drops to the oscillatory support line, if holding short orders, the short orders will be closed and multiple orders will be intervened. At the same time, falling below the oscillatory support line will be used as the stop loss point for multiple orders.

Secondly, in an oscillatory market, when the price rises to the upward pressure line, multiple positions can be closed and short orders can be sold, while breaking the oscillatory pressure line as the stop loss point for short orders.

　　二、趋势线的高级应用——捕捉行情转折点

　　利用趋势线来捕捉行情的转折点，是趋势线应用中较高的境界，但该技巧较难掌握。

　　在下降压力线和下降支撑线处逐渐收敛，在交汇点处形成了行情转折点A，行情向上突破进入上涨时期。投资者在交易过程中要把寻找行情转折点作为技术分析的重点，以博取较大的利润空间。

　　三、趋势线应用中需注意的几个问题

　　1.Time period of trend line

Trends can be divided into long-term trends, medium-term trends, and short-term trends based on the length of time. In practical practice, the author generally defines the trend line formed by the daily line as a short-term trend, the trend line formed by the weekly line as a midline trend, and the trend formed by the monthly line as a long-term trend.

Corresponding to the three types of trends mentioned above, the trading methods are short-term trading, midline trading, and long-term trading. Each trader should choose their own trading method based on their own trading characteristics to determine the trend cycle. In trend analysis, investors need to analyze the market in chronological order of long-term, medium-term, and short-term. After determining the medium to long-term trend, analyzing the short-term market will have a higher accuracy. Long term trends, which span several months or even years, are not suitable for general investors. Therefore, investors should focus their analysis on the analysis of mid-term and short-term trends.

　　2.The mutual conversion between trend lines

The pressure line and support line in the trend line are not fixed. After the price breaks through the pressure line, the pressure line may evolve into a support line for future trends. After the price falls below the support line, the support line may evolve into a pressure line for future trends. Investors should pay attention to the flexible application between pressure and support lines when applying trend lines.

　　3.Validity of trend lines

When drawing trend lines, there are many controversies about how to choose high and low points, including choosing the highest or lowest price that appears on the current day (or week or month) of the market, as well as choosing the closing price, and so on. The author believes that the true meaning of a trend line is to indicate the direction of market development, and a good trend line should be able to cover80%The above market trends. Therefore, the more points a trend line connects, the higher its accuracy. Investors can combine a large number ofKRepeatedly verify the line chart to obtain the trend line that is closest to the direction of market development.

The above provides a brief analysis of the application of trend lines in futures. Investors can further explore and research during the trading process, conduct in-depth improvement, and gradually form their own trading system and strategy.
