uments define the quantity, the type of goods, and in some cases
the quality of a particular commodity. In the past, the size of a con-
tract was based on the quantity that would fit into a single railroad
car: 5,000 bushels for grains, 112,000 pounds for sugar, 1,000 bar-
rels for oil, and so on. For this reason, contracts sometimes are
referred to as cars.
Trading takes place in units of a single contract: You cannot buy
or sell less than one contract. The exchange’s contract specifica-
tion also defines the minimum price fluctuation. This is referred
to in the industry as a tick or minimum tick.
A contract for British pounds is defined by the CME to be 62,500
British pounds, and the minimum tick is a hundredth of a cent, or
$0.0001. Thus, each tick of price movement is worth $6.25. This
means that Sam stands to make $62.50 for every tick in the spread
because he sold 10 contracts. Since the spread at the time he sold
the contracts to ACME was two ticks wide at $1.8450 bid and
$1.8452 ask, Sam will try to buy 10 contracts at the other side of the
spread at $1.8450 immediately. If he buys successfully at $1.8450,
this will represent a profit of two ticks, or just over $100. Sam buys
his 10 contracts from a large speculator, Mr. Ice, who is trying to
accumulate a position betting on the price going down; this is known
as a short position. Mr. Ice may hold those contracts for 10 days or
10 months, depending on how the market moves after this purchase.
So, there are three types of traders involved in this transaction:
• The hedger: ACME Corporation’s trader in the hedging
department, who wants to eliminate the price risk of
currency fluctuation and hedges by offsetting that risk in the
market
6 • Way of the Turtle
