If you want to accurately find out the "support level" and "resistance level", you can judge it in the following three ways.

1, average

The moving average has two major functions: one is to indicate the direction; The other is to provide a basis for judging the support resistance. Because the moving average takes the average of the closing prices for many days, it has corresponding support and pressure on the fluctuation of exchange rate. When the exchange rate returns to the vicinity of the moving average, investors tend to rebound at the bottom, thus forming obvious support there.

However, when analyzing the short-term support resistance by using the moving average, it should generally conform to the principle of large-period small moving average and small-period large moving average. For example, looking at the daily line, we generally pay attention to the resistance of the 5-day, 10 and 20-day moving averages. If it is a 60-minute chart or a 15-minute chart, generally look at the moving average of 100, with 200 cycles.

2. Bollinger Band

Bollinger Bands generally judge the support resistance level by observing the upper rail, middle rail and lower rail.

Generally speaking, the bollinger band does not change much in the leveling stage, when the support level and resistance level are relatively stable, which is also the best time for high-throwing and low-sucking operation. However, investors should also note that when the bollinger band is flat, it is even more necessary to set a stop loss to prevent a breakthrough.

3, the golden section line

The golden section is the most common and effective way to find support and resistance.

Just open the chart, use the golden section index to connect two relative high points and low points in a period of time with the low point as the base point, and judge the support point of the price according to the corresponding point of each golden section line. The judgment of pressure level is based on the relative high point.
