Huasheng software 4-line tutorial?

Watson's four-line selection method is a commonly used stock technical analysis method, which is mainly used to judge the rise or fall of stock price trend. The method is based on the following four lines:

1. support line: refers to the horizontal line where the stock price rebounds and is supported here.

2. Pressure line: refers to the horizontal line where the stock price rebounds and is under pressure.

3. Upward trend line: a straight line connecting two relatively low points, which is used to judge whether the stock price is in an upward trend.

4. Downward trend line: a straight line connecting two relatively high points, which is used to judge whether the stock price is in a downward trend.

The following is a four-line selection tutorial for Huasheng:

1. First observe the historical trend chart of the stock price, find out the horizontal line where the stock price rebounds and is supported or pressured, and draw the support line and pressure line.

2. Connect two relative low points on the chart to get an upward trend line; Connect two relatively high points to get a downward trend line.

3. According to the position and direction of the trend line, judge the trend of the stock price and the possible future development trend.

Regarding doing architecture tutorial, if you mean architecture design in software development, you can refer to the following steps:

1. Define requirements: define the functional requirements and business processes of the software.

2. Partition module: Divide the whole software system into several modules, and each module has its own functions and responsibilities.

3. Interface design: Design interfaces between modules to realize data transmission and communication between modules.

4. Choose technology: Choose appropriate technical framework and tools to ensure the stability and scalability of the software system.

5. Code writing: Write the code according to the designed architecture scheme, and test and debug it.

6. Optimize performance: optimize the performance of the software system to improve the operating efficiency and stability of the system.

The above is just a simple software architecture design process, and the specific situation needs to be analyzed and handled according to the actual project.
