There are many advantages to trading spot
money market as opposed to trading stocks and futures.
1. Bid/Ask Spread rates
Spread rates have tightened dramatically
in the last years. Most online money market 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 money market 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-Money market.
3. 24 hour market
Money 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 money market
options, however, is their higher premiums. On average, SPOT
option premiums cost more than standard money market
options.
Why Trade Money Market Options?
There are several reasons why money
market 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) money market position.
-
You get to set the price and
expiration date. (These are not predefined like those of
money market options on futures.)
-
Money market 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 money market options to trade on predictions of
market movements before fundamental events take place
(such as economic reports or meetings).
-
SPOT money market options give you
many choices:
-
Standard money market 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 money market 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 money market 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.
Money Market Options Prices
Money market 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 money
market 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
money market 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
Money market 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
Money market options are a good way to
profit while keeping the risk down – after all, you can lose
no more than the premium! Many money market traders like to
use money market options around the times of important
reports or events, when the spreads and risk increase in the
cash money markets. Other profit-driven money market traders
simply use money market options instead of cash because
money market options are cheaper. A money market options
position can make a lot more money than a cash position in
the same amount.
Hedging Strategies
Money market options are a great way to
hedge against your existing positions to decrease risk. Some
traders even use money market options instead of or together
with stop-loss points. The primary advantage of using money
market 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 Money Market Options
Money market options are often used in
combinational strategies with other money market 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 money market 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 money market 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.
