There are
many advantages to trading spot foreign exchange as opposed
to trading stocks and futures.
1.
Bid/Ask Spread rates
Spread
rates have tightened dramatically in the last years. Most
online foreign exchange brokers offer a spread of 5 pips on
EUR/USD which is currently the most widely traded and liquid
currency pair. In the futures market spreads can vary
anywhere between 5 and 9 pips and can become even larger
under illiquid market conditions (which tends to happen
substantially more often in futures currencies).
2.
Margins requirements
Usually
foreign exchange trading with a 1% margin is available. In
layman's terms that means a trader can control a position of
a value of USD 1'000'000 with a mere USD 10'000 in his
account. By comparison, futures margins are not only
constantly changing but are also often quite sizeable.
Stocks are generally traded on a non-margined basis and when
they are, it can be as restrictive as 50% or so. You can
start with as little as 25 USD in Easy-Foreign exchange.
3.
24 hour market
Foreign
exchange market trading occurs over a 24 hour period picking
up in Asia around 24:00 CET Sunday evening and coming to an
end in the United States on Friday around 23:00 CET.
Although ECNs (electronic communications networks) exist for
stock markets and futures markets (like Globex) that supply
after-hours trading, liquidity is often low and prices
offered can often be uncompetitive.
4.
No Limit up / limit down
Futures
markets contain certain constraints that limit the number
and type of transactions a trader can make under certain
price conditions. When the price of a certain currency rises
or falls beyond a certain pre-determined daily level traders
are restricted from initiating new positions and are limited
only to liquidating existing positions if they so desire.
This mechanism is meant to control daily price volatility
but in effect since the futures currency market follows the
spot market anyway, the following day the futures market may
undergo what is called a 'gap' or in other words the futures
price will re-adjust to the spot price the next day. In the
OTC market no such trading constraints exist permitting the
trader to truly implement his trading strategy to the
fullest extent. Since a trader can protect his position from
large unexpected price movements with stop-loss orders the
high volatility in the spot market can be fully controlled.
5.
Sell before you buy
Equity
brokers offer very restrictive short-selling margin
requirements to customers. This means that a customer does
not possess the liquidity to be able to sell stock before he
buys it. Margin-wise, a trader has exactly the same capacity
when initiating a selling or buying position in the spot
market. In spot trading when you're selling one currency,
you're necessarily buying another.
A
disadvantage of SPOT foreign exchange options, however, is
their higher premiums. On average, SPOT option premiums cost
more than standard foreign exchange options.
Why Trade Foreign exchange options?
There are
several reasons why foreign exchange options in general
appeal to many traders:
-
Your
downside risk is limited to the option premium (the
amount you paid to purchase the option).
-
You
have unlimited profit potential.
-
You pay
less money up front than for a spot (cash) foreign
exchange position.
-
You get
to set the price and expiration date. (These are not
predefined like those of foreign exchange options on
futures.)
-
Foreign
exchange options can be used to hedge against open spot
(cash) positions in order to limit risk.
-
Without
risking a lot of capital, you can use foreign exchange
options to trade on predictions of market movements
before fundamental events take place (such as economic
reports or meetings).
-
SPOT foreign exchange options give you many choices:
-
Standard foreign exchange options.
-
One-touch SPOT – You receive a payout if the price
touches a certain level.
-
No-touch SPOT – You receive a payout if the price
doesn't touch a certain level.
-
Digital SPOT – You receive a payout if the price is
above or below a certain level.
-
Double one-touch SPOT – You receive a payout if the
price touches one of two set levels.
-
Double no-touch SPOT – You receive a payout if the
price doesn't touch any of the two set levels.
So, why isn't everyone using foreign exchange options? Well,
there also are a few downsides to using them:
-
The
premium varies according to the strike price and date of
the option, so the risk/reward ratio varies.
-
SPOT
foreign exchange options cannot be traded: once you buy
one, you can't change your mind and then sell it.
-
It can
be hard to predict the exact time period and price at
which movements in the market may occur.
-
You may
be going against the odds.
Foreign exchange options Prices
Foreign
exchange options have several factors that collectively
determine their value:
-
In the money
– This means the strike price is higher than the
current market price.
-
Out of the money
– This means the strike price is lower than the
current market price.
-
At the money
– This means the strike price is at the current
market price.
-
The time value
– This represents the uncertainty of the price over
time. Generally, the longer the time, the higher premium
you pay because the time value is greater.
-
Interest rate differential
– A change in interest rates affects the relationship
between the strike of the option and the current market
rate. This effect is often factored into the premium as
a function of the time value.
-
Volatility
– Higher volatility increases the likelihood of the
market price hitting the strike price within a limited
time period. Volatility is factored into the time value.
Typically, more volatile currencies have higher foreign
exchange options premiums.
How It Works
– A Scenario.
Say it's
January 2, 2004, and you think that the EUR/USD (euro vs.
dollar) pair, which is at the time at 1.3000, is headed
downward due to positive U.S. numbers; however, there are
some major reports coming out soon that could cause
significant volatility. You suspect this volatility will
occur within the next two months, but you don't want to risk
a cash position, so you decide to use foreign exchange
options.
You then go
to your broker and put in a request to buy a EUR put/USD
call, commonly referred to as a "EUR put option," set at a
strike price of 1.2900 and an expiry of March 2, 2004. The
broker informs you that this option will cost 10 pips, so
you gladly decide to buy.
This order
would look something like this:
Buy: EUR put/USD call
Strike
price: 1.2900
Expiration:
2 March 2004
Premium: 10
USD pips
Cash (spot)
reference: 1.3000
Say the new
reports come out and the EUR/USD pair falls to 1.2850--you
decide to exercise your option, and the result gives you 40
USD pips profit (1.2900 – 1.2850 – 0.0010).
Option Strategies
Foreign
exchange options can be used in a variety of ways, but they
are usually used for one of two purposes: (1) to capture
profit or (2) to hedge against existing positions.
Profit Motivated Strategies
Foreign
exchange options are a good way to profit while keeping the
risk down – after all, you can lose no more than the
premium! Many foreign exchange traders like to use foreign
exchange options around the times of important reports or
events, when the spreads and risk increase in the cash
foreign exchange markets. Other profit-driven foreign
exchange traders simply use foreign exchange options instead
of cash because foreign exchange options are cheaper. A
foreign exchange options position can make a lot more money
than a cash position in the same amount.
Hedging
Strategies
Foreign
exchange options are a great way to hedge against your
existing positions to decrease risk. Some traders even use
foreign exchange options instead of or together with
stop-loss points. The primary advantage of using foreign
exchange options together with stops is that you have an
unlimited profit potential if the price continues to move
against your position.
Hedge
ratio
An option
price does not fluctuate in a one-to-one relationship with
the fluctuations in the price of the underlying asset. This
is because as the option strike price becomes closer to or
further away from the current asset price, the probability
of the strike price being in the money changes. In the graph
below, you can see the relation of the option price to the
underlying asset price. The word used to describe the
relationship of the option’s price change to the underlying
asset’s price change is the hedge ratio or delta. As you can
see, as the option becomes more and more heavily in the
money, the option value’s price will fluctuate very closely
with the underlying asset price, meaning that the delta is
approaching 1. But as the strike price becomes further and
further out of the money, the delta approaches zero, as the
probability that the option will have any intrinsic value on
expiration also approaches zero.
Hedging with foreign exchange options
Foreign
exchange options are often used in combinational strategies
with other foreign exchange options, or as a hedging tool
for a spot position. A hedging strategy can be initiated to
reduce a potential loss on the investment. If the investor
buys a spot position at a price of 100, he has a profit/loss
scenario as shown in the left-hand figure below. If the
investor buys a put option, he can change the profit/loss
scenario and reduce a potential loss. This is illustrated in
the right-hand graph below. The advantage of hedging with
foreign exchange options instead of using a ”stop” is that
you can stay in the market despite movements against your
underlying position and still have an unlimited profit
scenario. The disadvantage is that you must have a larger
gain in the spot before the position makes a profit because
you must pay for the option.

Hedging example
You
speculate that the exchange rate of EUR/JPY will decline
steeply in the next week and have the capital to sell
1,000,000 EUR/JPY on margin at the spot price of 105.00. Now
you want to protect your position in case of a rise in the
EUR/JPY rate.
Protection
can be done in two ways
1) you can
place a stop order, or
2) buy an
option.
1) Placing
a stop
Let’s say
that you consider placing a stop, based on your analysis, at
106.00. Placing a stop order, you will, of course, limit the
potential for loss to JPY 1,000,000 (around 9,434 EUR) if
the stop (106) is traded, thereby closing your position.
2) Buy an
option
The other
way of protecting yourself from limitless downside in this
scenario is with the purchase of a call option. Let’s say
that you purchase a one-week call option with the same
strike price as the stop-loss order (106.00) at a cost of
JPY 300,000 (EUR 2,857). As the holder of this option, you
will maintain the potential for unlimited profit because
your spot position can stay open until the exercise date
without having to worry about losing more than the option
premium (JPY 300,000) and the (JPY 1,000,000) loss when the
price is at 106.00. The option will protect any final price
above that level. That’s because the call option gains value
as the spot loses value. In other words, this option
scenario can give you a staying power that is not possible
with the use of stops. In any market, entering the market
several times and hitting multiple stop losses is much more
costly than establishing a more strategic foreign exchange
options position. This is especially true in cases with high
volatility.
The two
strategies are shown in the graphic below. The thick blue
line shows the profit/loss scenario for the hedged position.
Keep in mind that in sideways markets, an option buying
strategy can become costly because you are paying for time
value that quickly erodes as the expiration date approaches.
Profit and Loss - Hedge
Another
potential advantage of a hedging strategy is this: in the
course of the option’s life, you may reassess your view of
the market and wish to actually close the short spot
position (even at a loss) in the expectation that the market
is going the other way. In this scenario, you close the
short position but keep the option, hoping that it will come
in the money before expiration. For example, let’s say that
after a few days, the spot price for EUR/JPY rises to 105.50
from the entry level of 105.00, and you have changed your
mind about the direction of the market. Since you believe
the rate will continue to rise, you close your spot position
for a loss, but hang on to your option until the expiration.
At any level above the break-even point of 106.3 you will
begin to make a profit. And again, the option itself might
be resold before expiration.
