Just visiting is designed according to the principle of Shays channel. Xue Si developed a unique set of analytical techniques when analyzing trends. The basic method is to draw the Scholes channel on the trend chart first, and then analyze and judge according to the Scholes channel. There are two main points in drawing the learning channel: first, most of the lines are required to be sandwiched between the upper and lower tracks; Second, the vertical distance between the upper and lower tracks is equal everywhere. Just visiting uses neural network technology to simulate the fuzzy thinking process when people draw Shears channel manually, and automatically draws Shears channel, which is more standardized and accurate than manual drawing. Because just visiting is drawn automatically, it is a step forward compared with the manual drawing method originally developed by Chaucer, so it is called just visiting in name, rather than a continuation of Chaucer's channel.
