There are 4
types of foreign exchange stop-orders in foreign exchange.
1. Equity
Stop
This is the
simplest of all stops. The trader risks only a predetermined
amount of his or her account on a single trade. A common metric
is to risk 2% of the account on any given trade. On a hypothetical
$10,000 trading account, a trader could risk $200, or about
200 points, on one mini lot (10,000 units) of EUR/USD, or only
20 points on a standard 100,000-unit lot. Aggressive traders
may consider using 5% equity stops, but note that this amount
is generally considered to be the upper limit of prudent money
management because 10 consecutive wrong trades would draw down
the account by 50%. One strong criticism of the equity stop
is that it places an arbitrary exit point on a trader's position.
The trade is liquidated, not as a result of a logical response
to the price action of the marketplace, but rather to satisfy
the trader's internal risk controls.
2. Chart
Stop
Technical analysis
can generate thousands of possible stops, driven by the price
action of the charts or by various technical indicator signals.
Technically oriented traders like to combine these exit points
with standard equity stop rules to formulate charts stops. A
classic example of a chart stop is the swing high/low point.
In the following figure, a trader with our hypothetical $10,000
account using the chart stop could sell one mini lot risking
150 points, or about 1.5% of the account.

3. Volatility
Stop
A more sophisticated
version of the chart stop uses volatility instead of price action
to set risk parameters. The idea is that in a high volatility
environment, when prices traverse wide ranges, the trader needs
to adapt to the present conditions and allow the position more
room for risk to avoid being stopped out by intra-market noise.
The opposite holds true for a low volatility environment, in
which risk parameters would need to be compressed.
One easy way
to measure volatility is through the use of Bollinger bands,
which employ standard deviation to measure variance in price.
The following two figures below show a high volatility and a
low volatility stop with Bollinger bands, respectively. In the
first figure the volatility stop also allows the trader to use
a scale-in approach to achieve a better "blended" price and
a faster breakeven point. Note that the total risk exposure
of the position should not exceed 2% of the account; therefore,
it is critical that the trader use smaller lots to properly
size his or her cumulative risk in the trade.


4. Trailing
Foreign Exchange Stop Orders
A trailing
foreign exchange stop order is a foreign exchange stop order
that adjusts itself whenever the price moves by a specified
amount in the trader's favour.
Example: Let's
say that a foreign exchange trader that has a long, profitable
USD/JPY position, needs to leave his computer. He can do one
of two things:
-
He can
place a sell foreign exchange stop order a number of pips
below the current market price (say 30 pips) or
-
He can
place a trailing sell foreign exchange stop order using
a 30 pip stop that adjusts itself every 30 pips. This means
that every time the price moves up by 30 pips, the stop
is automatically moved up 30 pips in order to protect 30
more pips of profit. It is true that both foreign exchange
orders will protect the trader's existing profit, but only
the trailing foreign exchange stop order allows the trader
to continue participating in greater profits if they indeed
occur.
5. Margin
Stop
This is perhaps
the most unorthodox of all money management strategies, but
it can be an effective method in foreign exchange trading, if
used judiciously. Unlike exchange-based markets, foreign exchange
markets operate 24 hours a day. Therefore, foreign exchange
dealers can liquidate their customer positions almost as soon
as they trigger a margin call. For this reason, foreign exchange
customers are rarely in danger of generating a negative balance
in their account, since computers automatically close out all
positions.
This money
management strategy requires the trader to subdivide his or
her capital into 10 equal parts. In our original $10,000 example,
the trader would open the account with an foreign exchange dealer
but only wire $1,000 instead of $10,000, leaving the other $9,000
in his or her bank account. Most foreign exchange dealers offer
100:1 leverage, so a $1,000 deposit would allow the trader to
control one standard 100,000-unit lot. However, even a 1 point
move against the trader would trigger a margin call (since $1,000
is the minimum that the dealer requires).
So, depending
on the trader's risk tolerance, he or she may choose to trade
a 50,000-unit lot position, which allows him or her room for
almost 100 points (on a 50,000 lot the dealer requires $500
margin, so $1,000 – 100-point loss* 50,000 lot = $500). Regardless
of how much leverage the trader assumed, this controlled parsing
of his or her speculative capital would prevent the trader from
blowing up his or her account in just one trade and would allow
him or her to take many swings at a potentially profitable set-up
without the worry or care of setting manual stops. For those
traders who like to practice the "have a bunch, bet a bunch"
style, this approach may be quite interesting.
Some examples
of foreign exchange order's transactions:
Example of
OCO Transaction:
Buy: 1 standard
lot EUR/USD @ 1.3228 = $132,280
Pip Value:
1 pip = $10
Stop-Loss:
1.3203
Limit: 1.3328
This is a foreign
exchange order to buy US dollars at 1.3328 and to sell them
if they fall to 1.3203 (resulting in a loss of 25 pips or $250)
or to sell them if they rise to 1.3328 (resulting in a profit
of 100 pips or $1,000).
Here's another
example:
Suppose, the
current bid/ask price for US dollars and Canadian dollars is
USD/CAD 1.2152/57
...meaning
you can sell $1 US for 1.2152 CAD or buy $1 US at 1.2157 CAD.
If you think
that the US dollar (USD) is undervalued against the Canadian
dollar (CAD) you would buy USD (simultaneously selling CAD)
and wait for the US dollar to rise.
This is the transaction:
Buy USD: 1
standard lot USD/CAD @ 1.2157 = $121,570 CAD
Pip Value:
1 pip = $10
Stop-Loss:
1.2147
Margin: $1,000
(1%)
You are buying
US$100,000 and selling CAD$121,570. Your stop loss order will
be executed if the dollar falls below 1.2147, in which case
you will lose $100.
However, if
USD/CAD rises to 1.2192/87. You can now sell $1 US for 1.2192
CAD or sell 1.2187 CAD for $1 US.
Because you
entered the transaction by buying US dollars (buying long),
you must now sell US dollars and buy back CAD dollars to realize
your profit. You sell US$100,000 at the current USD/CAD rate
of 1.2192, and receive 121,920 CAD for which you originally
paid CAD$121,570. Your profit is $350 Canadian dollars or US$287.19
(350 divided by the current exchange rate of 1.2187).
