In fact, the names of indicators can be seen in the upper left corner of these two pictures!

There is "VOL" in the upper left corner of the above picture, which means "volume". The trading volume is different from that of stocks, and the trading volume of stocks will not be so abruptly enlarged or reduced, because there are always so many tradable shares in the stock market except issuance and stock delivery. The same futures product has different monthly contracts. For example, when the main contract of soybean futures is 130 1, the volume of this contract is the largest, while other contracts are very small, almost none.

There is "macd" in the upper left corner of the figure below, which is the MACD indicator. What exactly is macd? You can Baidu it.
