How to calculate the support and resistance levels of a stock?

The support level and pressure level can be seen through the moving average. The level above the moving average is the pressure level, and the level below the moving average is the support level. When the stock price falls, it will not continue to fall at a certain point in time. The stock price at this point in time is called a support level. When the stock price rises, it will not continue to rise at a certain point in time. The stock price at this point in time is called the pressure level.
