Hello, logarithmic coordinates: the distance between scales in ordinary coordinates is directly proportional to the price. That is to say, in the ordinary coordinate system, all K-lines with equal ups and downs on that day have the same length. For example, all those that have gone up by 1 yuan from the opening to the closing.
K lines are the same length. However, in the logarithmic coordinate system, the distance between coordinate scales is directly proportional to the logarithm of the price. In other words, the K-line with the same fluctuation (%) on the same day has the same length.
