Generally speaking, the early high point is the most common pressure level, and the early low point is the most common support level. To find the pressure level and support level, we need to be familiar with their generation principles.

The principle of stock pressure level is as follows: when the stock price rises to a certain range, a lot of selling pressure is generated, resulting in oversupply, then the stock price will fall under pressure and fall back under pressure for many times, then this position will form a stock pressure level;

The principle of stock support level is that a large number of transactions were made in a certain stock price range in the previous stage, and this position generally becomes the cost price of shareholders' positions. The supply in this price range will gradually decrease, and the demand exceeds the supply, which will naturally form the stock support level.
