What is Futures ?
Futures is

A contract into which parties enter to either buy or to sell Underlying
assets in the future and the contract’s parties must adhere to the contract.
Party who agrees to buy underlying assets in the future is called Long
Futures or to have a Long Position
Party who agrees to sell underlying assets in the future is called Short
Futures or to have a Short Position
When entering into a contract, there will be a fixing of prices for buying
or for selling in order to make a delivery of underlying assets or to make
a cash settlement in the future.
Profit of one party will be equal to a loss of another party or we call
Zero sum Game.
On a date when parties enter into a contract, both parties will agree on
prices for buying and selling in the future but there will be no settlement
on that date. Delivery and settlement of price for underlying assets will
be done in the future when the contract’s maturity date arrives.

SET50 index and price of Futures are different figures and

Calculating SET50 Index Futures Price
Today (t=0)
In Between
Expiration (t=T)
Buying Stock
• Paying a spot
price
• Receive shares
immediately
• Entitle to receive
dividend
• Cost of paying cash
(interest)
• Already holding shares
with net cost S +
Interest
• Dividend
Buying
Futures
• Agree on price
for futures
• No rights to
dividend
• Payment on futures
• Receive shares
At the expiration date, we will have shares in our hand on both cases, buying on spot and
buying futures. Therefore, the cost of acquiring shares on both cases should be the same as
follows:
F=S + Interest – dividend
It can be seen that Futures price (F) is differed from spot price (S) on the value of paid
interest deducted by dividend which is the net cost of carrying this stock. Therefore, we call the
formula showing this relationship the Cost of Carry model or cost of carrying theory.
Example: spot price of share S = 500, interest = 30, dividend =20
Price of futures in theory =500+30-20 = 510

Q = Dividend yield rate
T = Remaining period before expiration
Value of underlying assets
i.e. 500,000 Baht
Cost of Carry formula to calculate Futures price in theory
F = S + Interest - dividend
F = S + S*R*T-S*Q*T
i.e. Futures (F) is 510 when SET50 (S) is 500 point
Price of SET50 Futures traded in the market will also depend
on demand & supply of investors. Market price of Futures
can be differed from price in theory at a certain level.
32
Example of theoretical price setting of SET50 Futures
Assuming that
the current SET50 index is at 500 points (S=500)
Dividend payment rate = 4 % (Q=0.04)
Interest rate = 6% (R=0.06)
What Futures price, one year term (t=T) should be (F=?)
F = S + interest – dividend
F=S+S*R*T–S*Q*T
= 500 + 500 * 0.06 * 1 – 500 * 0.04 * 1
= 500 + 30-20
= 510
= Theoretical price of one-year term SET50 Futures
33
Example of theoretical price setting of SET50 Futures
Futures price (F) can be higher or lower than the current price (S)
F
= S + Interest-dividend
= S+S*R*T -S*Q*T
= S + S * (R-Q) * T
If interest rate (R) > dividend rate (Q), then F>S
If interest rate (R)< dividend rate (Q), then F<S

Order Types : SET50 Futures
Limit Order (Specify exact price)
The most common order type is the limit order.
Limit orders can only be traded when the trading
price is better or equal to the limit price of the order.
Market Order
The most simple order type is the market order. A
market order is an order to buy or sell a quantity (a
certain number of contracts) at the best price. In
other words, a market order is traded immediately as
long as there is an order to match. Market orders are
not allowed to stay in the Orderbook.
Stop Order
Condition order. If the input condition is met, then
the sent order will begin to match in the market.
Combination Orders
Standard (2 series, time spread combo) is the
Calendar spread order that can get long position in
one series and short position in other series.
Fill and Store (FaS, Day)
The Fill and Store (FaS) order must have a limit
price. As much of the order as possible is traded,
and the rest is stored it in the Order book.
Fill and Kill (FaK)
The Fill and Kill (FaK) order is traded as far as
possible until its quantity is filled, or until there are
no more matching orders. In either case, the rest
quantity of the order is rejected (killed) and Fill and
Kill orders are therefore not stored in the Order
book.
Fill or Kill (FoK)
The most complex order type is the Fill or Kill
(FoK) order. When the Marketplace receives a FoK
order, it tries to match the entire quantity. If the
order can be fully filled, the trade is done.
Otherwise no trade will take place, and the entire
order is rejected. In other words either the whole
quantity is traded, or nothing at all. The Fill or Kill
order cannot be stored in the Order book.

Placing Margin

Margin is client’s one lump sum of cash but is observed into
levels of initial margin and maintenance margin “Margin
money is equate to Green-tea refill. If green tea is reduced to
one certain level – called maintenance level, it will be
refilled back to a full glass again”.
Placing margin by clients :
Margin

• Level of initial margin (Initial
• Level of initial margin (Initial

• Level of Maintenance margin
• Level of Maintenance margin
(Maintenance margin = MM) =
(Maintenance margin = MM) =

35,000 Baht / 1 contract
Example 1 : Margin Calll
When margin amount declines to
32,000 Baht, there will be a call
(call margin) to increase margin
by 18,000 Baht
50,000 Baht
35,000 Baht
Example 2 : Excess Margin
Margin = 60,000 will equal to
having excess margin of
10,000 Baht which can be

Investing directly in the basket of stocks will
render returns = 10/500 = 2%
It can be seen that
investing in Futures
renders higher returns
and also higher risks
than investing directly in
stock
Futures is an
investment with high
risk and high return
Futures has leverage
that is to use small
amount of money for
investment but returns is
large (both
positive/negative)

Longing SET50 Futures
will render returns =
10,000/50,000 = 20%
Shorting SET50 Futures
will render returns =
-10,000/50,000 = -20%

Summary of Important Issues

Longing or Shorting SET50 Futures is an agreement to buy or sell SET50
index in advance by agreeing on price at the contract entering date.
Price of SET50 Futures depends on Cost of Carry Model and Demand and
Supply of the market
Price of SET50 Futures (F) is a different figure from SET50 Index (S) and
they have different values but the convergence of F and S will cause the
two figures to be equal on the futures expiration date.
Client’s margin money will be one lump sum but will be observed into
levels of initial margin and maintenance margin.
Mark-to-market is to record profit/loss every day by using settlement price
of SET50 futures for mark-to-market purpose but not using SET50 index
level.
If the market rises, Long SET50 Futures will make profit while Short
SET50 Futures will suffer loss.

Credit Risk Management and Margin Call
1.
Trading agent must prepare for client to completely place margin within the following time frame:
1.1. In a case of initial margin placement
1.1.1. Clients who are not institutional clients must place margin before trading of futures contract. If
margin is not placed, the system will not be activated for trading.
1.1.2. For institutional clients, margin must be placed at least one hour before the closing hour of the
following day after the trading day.
1.2. In a case of additional placement of margin, additional margin must be placed at least one hour before
the closing hour of the following day after the day the agent asks investor to place additional margin.
2.
In an event that any client can not place margin within required period as stated in 1.1.2 or 1.2, an agent must
follow the following guidelines:
2.1. Stop trading on futures contract resulting in a new position for the said client.
2.2. Close position on Futures trading of such client at least one hour before the closing hour of the following
working day. The agent must close position for Futures trading of such client to the point that rate or value
of margin of that client is not lower than the rate or value of the client’s initial margin for the remaining
position.
3.
Credit and Risk Management Department has a duty to ask client to place assets as initial margin and to set
up maintenance margin at the rate or value not lower than that required by SEC or as announced by
Thailand’s Clearing House
4.
When rate or value of margin of that client is lower than the rate or value of maintenance margin as required
by the company (the company’s rate is not lower than that of Thailand’s Clearing House), the client will be
asked to place additional margin at an amount that will make rate or value of the margin to be not lower than
the rate and value of initial margin. The type of assets that agent asks client to place as margin must be the
same type of assets required by Thailand’s Clearing House for its member to place as margin. Currently,
Thailand’s Clearing House accepts only cash as margin.
