股票趋势图怎么画

股票趋势图的绘制对于投资者来说是一项重要的技能，它能够帮助我们更好地理解股票的走势，从而做出更明智的投资决策。

首先，我们需要明确趋势的分类。趋势分为长期趋势、中期趋势和短期趋势。在绘制趋势线之前，我们必须清楚自己所选择的是哪种趋势。对于长期趋势线，应以长期的波动点作为画线依据，例如使用周线或较长时间内的日 K 线；而短期趋势线则可以使用 30 分钟或 60 分钟 K 线作为波动点来进行画线。

接下来是开始画线。在初始阶段，我们要先画出一些实验性的线段来进行验证。等待股价运行一段时间后，保留那些能够准确反映出趋势波动的线段，淘汰其余不准确的线段。

然后要注意趋势线的修正问题。在上升趋势中，如果股价跌破了趋势线之后又能快速回到趋势线之上，那么就需要对趋势线进行修正。我们需要将最后一个低点改为最新的低点，这样趋势线的角度会产生变化，从而能够更准确地反映股价的走势。下降趋势线同理，一旦股价反弹突破了上一个高点，也需要更改最后一个高点来重新修正。

此外，我们所画的趋势线角度不应过大。因为角度过大的趋势线很容易被横盘突破，从而失去了分析的意义。所以，不要选择两个相邻差别很大的低点或高点来画趋势线。

一般来说，所画出的趋势直线只需要两个低点或高点即可构成，但趋势线被触及的次数至少三次，才能确认趋势线的有效性。如果运用趋势线可以帮助投资者展开顺势而为的操作，即寻找股价运动的趋势，在上升趋势时买入并持有，在下跌趋势时卖出股票而持币观望。

How to Draw Stock Trend Charts

Drawing stock trend charts is an important skill for investors. It helps us better understand the stock's movement and make wiser investment decisions.

Firstly, we need to clarify the classification of trends. Trends are divided into long-term, medium-term, and short-term trends. Before drawing the trend line, we must be clear about which trend we are choosing. For long-term trend lines, the long-term fluctuation points should be used as the basis for drawing, such as using weekly lines or longer-term daily K-lines; while for short-term trend lines, 30-minute or 60-minute K-lines can be used as the fluctuation points for drawing .

Next is to start drawing. In the initial stage, we need to draw some experimental line segments for verification. After the stock price has run for a period of time, retain the line segments that can accurately reflect the trend fluctuations and eliminate the inaccurate ones .

Then, pay attention to the correction of the trend line. In an uptrend, if the stock price falls below the trend line and then quickly returns above it, the trend line needs to be corrected. We need to change the last low point to the latest low point. This way, the angle of the trend line will change, enabling it to reflect the stock price movement more accurately. The same applies to the downtrend line. Once the stock price rebounds and breaks through the previous high point, the last high point also needs to be changed for re-correction .

In addition, the angle of the trend line we draw should not be too large. Because a trend line with a too-large angle is easily broken through by sideways movement, thus losing its significance for analysis. Therefore, do not choose two low or high points that are significantly different from each other to draw the trend line .

Generally speaking, the drawn trend line only requires two low or high points to form, but the trend line needs to be touched at least three times to confirm its validity. If the trend line can be used to help investors carry out trend-following operations, that is, to find the trend of the stock price movement, buy and hold in an uptrend, and sell the stock and hold cash in a downtrend.
