Eurodollar Futures 	Eurodollar Futures
Contract Unit 	$2,500 x Contract IMM Index
Price Quotation 	Contract IMM Index = 100 minus R
R = three-month London interbank offered rate for spot settlement on 3rd Wednesday of contract month.
E.g., a price quote of 97.45 signifies a deposit rate of 2.55 percent per annum. One interest rate basis point = 0.01 price points = $25 per contract.
Trading Hours 	SUN - FRI: 5:00 p.m. - 4:00 p.m. CT
Minimum Price Fluctuation	Nearest expiring contract month:
One quarter of one interest rate basis point = 0.0025 price points = $6.25 per contract.
All other contract months:
One half of one interest rate basis point = 0.005 price points = $12.50 per contract.
The “new” nearest contract begins trading in 0.0025 increments on the same trade date as the last trading day in the expiring “old” nearest contract.
