Forward Contract
Forward is just a contract to deliver at a future date
(exercise date or maturity date) at a specified
exercise price.
Example: Rice farmer sells rice to warehouser.
Example: Foreign Exchange (FX) forward. Contract
to sell £ for ¥.
Both sides are locked into the contract, no liquidity.
What will warehouse think if rice farmer tries to get
out of the contract?
Futures Contracts
Futures contracts differ from forward contracts in that
contractors rather than each other, deal with an exchange
and thus do not need to assess each others’ credit.
Futures contracts are retail products, rather standardized
than custom products.
Futures contracts rely on margin calls to guarantee
performance.

Chapter 7
Introduction to Futures
Futures are very similar to forwards
A futures contract is an agreement to (if you are ) buy long
or (if you are ) something in the future, at an sell short
agreed upon price (the futures price).
Futures exist on (debt instruments, financial assets
currencies, stock indexes), and (gold, crude oil, real assets
wheat, cattle, cotton, etc.)
A Comparison of Futures Contracts
and Forward Contracts
Both types of contracts specify a trade between two counter-
parties:
There is a commitment of an asset (this is the , to take delivery buyer
or the )long
There is a commitment an asset (this is the , or the to deliver seller
short)
Many times, futures contracts and forward contracts are
substitutes.
However, at specific times, the relative costs, liquidity, and
convenience of using one market versus the other will differ.

Other Unique Features of Futures Contracts
Some futures contracts have daily price limits.
Some futures contracts (Euro$, T-bills, stock index futures,
currencies) have one specific delivery date; others (T-bonds, crude
oil) give the short the option of choosing which day (usually in the
delivery month) to make delivery.
Some futures contracts (e.g., T-bonds) let the seller choose the
quality of good to deliver, within a specified quality range.
Some futures contracts (Euro$, stock index futures, feeder cattle)
are cash settled.
Note that a futures contract is like a portfolio of forward
contracts (time series).

Futures Prices
The or opening price is the price or range of prices for open
the day's first trades, registered during the period designated
as the opening of the market or the opening call.
The word refers to the highest price at which a high
commodity futures contract traded during the day.
Low refers to the lowest price at which a commodity futures
contract traded during the day.
Some publications show a or close closing price in their
tables. The closing price is the price or range of prices at
which the commodity futures contract traded during the brief
period designated as the market close or on the closing
call—that is, the last minute of the trading day.
Because the last few minutes of trading are of ten the busiest
part of the day, with many trades occurring si multaneously,
the exchange computes a settlement price from the range
of closing prices. The settlement price, which is abbrev iated
as in most pricing tables, is used by the clearing settle
house to calculate the market value of outstanding positions
held by its members. It is also frequently used
synonymously with closing price; although they may, in fact,
differ.
The refers to the change in settlement prices from change
the previous day's close to the current day's close.
The lifetime high and low refer to the highest and lowest
prices recorded for each contract maturity from the first day
it traded to the present.
Open interest refers to the number of outstanding contracts
for each maturity month. Some newspapers do not include
this information.

Part of the daily cash flow system used by U.S.
futures exchanges to maintain a minimum level
of margin equity for a given futures or option contract
position by calculating the gain or loss in each contract
position resulting from changes in the price of
the futures or option contracts at the end of each trading
session. These amounts are added or subtracted to each
account balance.
