问题如下:

A linear price scale is:

选项:

A.

inappropriate for a candlestick chart.

B.

better suited for analysis of short-term price movements.

C.

constructed with equal vertical distances corresponding to an equal percentage price change.

解释:

B is correct.

A linearly scaled (rather than a logarithmically scaled) chart is better suited for analysis of short-term price movements. A linear scale plots price against a vertical axis with an equal distance between prices, whereas with a logarithmic scale, equal vertical distances correspond to an equal percentage change. The difference between a logarithmic price chart and an arithmetic (linear) price chart can be small when analyzing a chart in the short term. However, major differences are apparent when analyzing longer-term charts (more than two years of price data).

麻烦 讲一下 linearly scaled 和 logarithmically scaled 谢谢。

嗨,努力学习的PZer你好:


这个正课里有讲的,linearly scaled 指Y轴是变化值, logarithmically scaled指Y轴是变化百分比,适用的条件不一样,B就是讲义上的结论。
