In foreign exchange transactions, the trading volume of currency pairs is usually calculated in US dollars. DDE indicator shows the trading volume and activity of a currency pair in the market in a specific period. This indicator can help traders understand the hot currency pairs and trading trends in the market, so as to formulate more effective trading strategies.

The calculation method of DDE index is to divide the transaction volume of a currency pair in a specific time period by the number of transactions in that time period. The trading volume is usually in US dollars, and the trading time is usually in standard lots (100000 currency units). The calculation formula is as follows:

DDE= the transaction volume of currency pairs in a specific time period ÷ the number of transactions of currency pairs in a specific time period.

For example, if the transaction volume of EUR/USD currency pair is 65,438+00,000,000 USD, and the transaction volume within 65,438+0 hours is 65,438+0,000 standard lots, then the DDE index of this currency pair is:

DDE= 10，000，000 \ 1，000= 10，000

However, it should be noted that the DDE indicator can only reflect the trading volume and activity of the market, and cannot directly reflect the price trend. Therefore, when making trading strategies, traders need to combine other technical indicators and fundamental information to obtain a more comprehensive market analysis.
