The long position in a Eurodollar contract gains value when LIBOR decreases. Price quotes on Eurodollar futures are calculated as 100 minus annualized 90-day LIBOR in percent. A change in 90-day LIBOR of 0.01% represents a $25 change in value on a $1 million Eurodollar futures contract. If LIBOR decreases from 3.64% to 3.58%, the contract price increases six ticks from 96.36 to 96.42, so the long position gains 6 × $25 = $150.
Treasury bond futures that have a face value of $100,000 are quoted as a percent of face value with fractions measured in 1/32nds. A bond futures quote of 102-16 represents 102 16/32, or 102.5% of $100,000, which is $102,500.
Currency futures contracts are set in units of the foreign currency and stated as USD/unit.
