Eurodollar futures actually belong to the category of interest rate futures. Financial markets quote interest rate futures at 100 minus last year's annualized interest rate (the so-called annualized interest rate is to turn the rate of return in a certain period into an annual rate of return), and the contract value of interest rate futures is settled as follows: contract size *[ 100-( 100- interest rate futures quotation) *

Because it is to avoid the risk of rising interest rates and the risk of falling European dollar futures prices, it is to establish short positions.
