以从切线理论角度看,趋势线是其中的一部分,它是将波动运行的价格的低点和低点连接或高点和高点连接而形成的直线。如果价格是按一个低点比一个低点高的运行方式来运行,所画出来的趋势线就是上升趋势线;If the price operates in a way where a high point is lower than a high point, the trend line drawn is the downward trend line. Another type is the horizontal extension of the low and high points of prices, without obvious upward and downward trends, which is known as horizontal consolidation or box consolidation.
趋势线可以分成支撑线和压力线,将价格波段运行的低点和低点连接成一条直线,就是支撑线;Connect the high and high points of the price band into a straight line, which is the pressure line. The length of the trend line is directly proportional to its importance. The distance between the first and second points of the long-term and medium-term trend lines should not be too close. If the distance is too close, the importance of the formed trend line will decrease.
趋势线的角度至关重要,过于平缓的角度显示出力度不够,不容易马上产生大行情;A trend line that is too steep is not sustainable and is often prone to quickly changing trends.
