In most cases, the price will be concentrated in a certain area, not a certain point; If so, I will think that the area is a "support zone" or a "resistance zone". It should be pointed out that the range should not be too large, otherwise it will be of no reference significance to investors.

The top or bottom of the futures market often constitutes resistance or support; The unfilled gaps in the technical drawings also form effective support or resistance levels; The EMA also helps investors to judge the support level and resistance level; Observing the trend line can also judge the future support and resistance of the market.

It should be noted that when the main support level is broken down, the support level is transformed into the main resistance level; When the main resistance level is broken, it becomes the main support level.

Another way to find the support level and resistance level is to observe the "retreat" of the price in the process of operation-that is, the price fluctuation opposite to the current trend, also called "adjustment" or "correction".
