How to draw the Ganzi line of stock futures?
Ganzi line, also called angle line, selects significant high points and low points. If the newly selected points are immediately replaced by innovative highs and lows, the selection points of Ganzi Line will also change. The high point is drawn as a descending Ganzi line, and the low point is drawn as an ascending Ganzi line.

There are two ways. First, you can draw a Ganzi line at a 45-degree angle from a key point. Second, use the downward line of 1: 1 to connect two important highs when falling, or use the upward line of 1: 1 to connect two important lows when rising, and you can draw a Ganzi line.

Each corner line represents time and space, and plays the role of support and resistance.

The results of logarithmic coordinates and ordinary coordinates will be different, and the results of angle lines in different periods will be different, so the daily use of transactions is a very complicated problem. After studying for more than a year, perhaps it is just a lack of knowledge and a superficial feeling, which is of little significance to the choice of trading points. However, the long-term support resistance of the Shanghai Composite Index is almost in line with the angle line. You can try to draw it in ordinary coordinates and logarithmic coordinates. It's amazing.
