A futures contract can be any physical commodity, such as corn, wheat or meat products. It can also be a financial instrument, such as government and treasury bonds, equity indices and currencies. There are also futures contracts based on energies, such as oil, natural gas and heating oil.

Below we will outline the following aspects of a futures contract:

• Contract Size 50x index (1/5 S&P Index)
• Value of 1.0 point USD 50
• Tick Size .25
• Tick Value USD 12.50
• Margin USD 4,000
• Exchange Chicago Mercantile Exchange (CME)
• Trading Hours (CET) 22:30 – 22:15

Contract Size

The size of one S&P E-mini contract is 1/5 the size of the standard S&P index.

Value of 1.0 point

Each point in the contract is worth USD 50, meaning that a S&P E-mini contract with a Bid price of 1,281.25 is actually worth USD 64,062.50 (64,075.00).

Tick Size/Value: A tick is the smallest allowable increment by which a futures contract can move or, in this instance, in increments of .25. Given the fact that 1 point is equal to USD 50, the value of 1 tick (.25 of a point) would be USD 12.50.

Margin

Futures contract margins are set by the exchange on which the contract is traded. Exchanges use a system called SPAN (Standard Portfolio Analysis of Risk) to determine the margin level for each contract. SPAN is a computer model that calculates the range of possible changes in price for a particular contract. The "worst case scenario," i.e. the most adverse change in price with the position a trader holds, is then used to calculate the initial margin. For this S&P E-mini contract, the initial margin is USD 4,000/contract.

Futures contracts also have what is called a maintenance margin, i.e. the amount required to hold the open Futures position. For the S&P E-mini contract, the maintenance margin is USD 3,150. If the margin on the trader's account falls below the maintenance margin, additional funds must be transferred or the number of open contracts on the account must be reduced. The margin associated with a particular contract is subject to change.

Exchange

The S&P E-mini is traded on the Chicago Mercantile Exchange.

S&P E-mini contracts can be traded between these hours.

ESU6, ZGZ6, YMM7 – What's It All Mean?

Futures contracts are named according to the type of contract that is traded, plus the month and year in which the contract will be delivered. For example, in the contract name ESU6, ES stands for E-mini S&P 500. U is for September and 6 stands for the year 2006. Each month has a specific letter of the alphabet assigned to it, as follows:
