OPTION STRATEGIES
As we described earlier, four possible
option selections exist for a trader: (1) long a call, (2) long a put, (3)
short a call, and (4) short a put. These four can be used independently,
together, or in conjunction with other financial instruments to create a number
of option-trading strategies. These combinations enable a trader to develop an
option-trading model which meets the trader’s specific trading needs,
expectations, and style, and enables him or her to anticipate every conceivable
situation in the market. This trading structure can be adapted to handle any
type of market outlook, whether it be bullish, bearish, choppy, or neutral.
Options are unique trading instruments.
They can be used for a multitude of purposes, providing tremendous versatility
and utility. Among their multiple applications are the following: to speculate
on the movement of an asset; to hedge an existing position in an asset; to
hedge other option positions; to generate income by writing option positions
against asset positions; and to generate additional income by writing options
against different quantities of options or the underlying asset, also known as
ratio writing. Due to the numerous option strategies that arise from these
applications and the fact that the scope of this book is limited, we will
devote coverage to a cursory explanation of two of the most popular strategies
which are designed to take advantage of market movement: spreads and straddles.
SPREADS
Option spreads are hedged positions
that can be utilized to control a trade’s risk, while at the same time limiting
gains. They accomplish this goal by simultaneously taking positions on both
sides of the market. A call option spread is the simultaneous purchase and sale
of call options with different strike prices, different expiration dates, or
with both different strike prices and different expiration dates. Likewise, a
put option spread is the simultaneous purchase and sale of a put option with
different strike prices, different expiration dates, or with both different
strike prices and different expiration dates. Spreads with different strike
prices are referred to as price spreads or vertical spreads because the strike
prices are stacked vertically on top of each other in financial listings.
Spreads with different expiration months are referred to as calendar spreads,
horizontal spreads, or time spreads because the options expire at different
times. A spread where both the strike price and the expiration month are
different is referred to as a diagonal spread.
Option spreads can be used when one has
an inclination as to where the underlying market is heading, but is somewhat
uncertain. Because the position is hedged, a spread allows the trader to
participate in the market while effectively containing risk, sometimes even
more so than with single option positions. Option spreads can also be used when
a trader has particular price targets in mind—because spreads limit gains as
well as losses, spreads can be initiated that will enable the trader to take
advantage of these targets while at the same time keeping risk at a minimum.
Vertical Spreads
As is the case with options, any of
four possible vertical option spreads can be selected depending on what a
trader expects will happen in the market: one can buy a call spread, one can
sell a call spread, one can buy a put spread, or one can sell a put spread. A
long call spread and a short put spread are considered bull spreads because
they are used when a trader’s market outlook is positive, or bullish. A short
call spread and a long put spread are considered bear spreads because they are
used when a trader’s outlook is negative, or bearish.
Buying a call spread. If a trader purchases a call option, he or she is looking
for the market to rally so the option can expire in-the-money and the trader
can profit. Likewise, a long call spread can be initiated to anticipate bullish
market conditions. A long call spread requires the purchase of a call option
with one strike price and the simultaneous sale of the same call option with a
higher strike price. Ultimately, when buying a call spread, the trader wants
both call options to expire in-the-money. With call options, the lower the
strike price, the greater the premium. Therefore, at the time the long call
spread is initiated, the premium that the trader pays for the call option with
the lower strike price will be greater than the premium that the trader
receives for the call option with the higher strike price. Since the trader
must pay a greater premium for the rights to the long call option than what he or
she receives for the short call option, the net premium cost is partially
offset in a bull call spread. Because the trader must put up some money upon
initiating the trade, this is considered a debit spread. To obtain the
break-even point of a long call spread, one would add the net cost of the
spread to the long call’s strike price (the lower strike price)—any value above
this break-even point is a gain on the trade and anything below this break-even
point is a loss on the trade.
The advantage of buying a call spread
is that it provides less risk than if one were to simply purchase a call option
outright. The most one can lose on the trade is the total cost (net premium
cost) of the spread—if both options of a long call spread were to expire
out-of-the-money, then the trader would lose the greater price paid for the
long call option position with the lower strike price and would retain the
lesser price received for the short call position with the higher strike price.
By selling a call option with a higher strike price, the trader receives some
additional income, thereby reducing the total cost of the spread and the
maximum loss. However, the drawback is that the gains are also limited. This
maximum gain is capped at the difference between the two call option strike
prices minus the total cost (net premium cost) of the spread. In any case, with
a long call spread, the potential gains are greater than the potential losses.
Example
Buy 1 Micron (MU) Jan 50 Call @ 4
Sell 1 Micron (MU) Jan 60 Call @ 1
Market price of Micron stock: $50
In this example, the trader has
initiated a long call spread. This trader has purchased one Micron call option
with a January expiration and a $50 strike price for $400 and has sold one
Micron call option with a January expiration and a $60 strike price for $100,
when Micron is trading at $50 per share. Therefore, the total cost of the
spread is $300. This payment is a nonrefundable, fixed cost to the trader and
cannot be recovered. This $300 is also the most a trader can lose on the
transaction—if both calls were to expire out-of-the-money, meaning Micron stock
were trading at any price below $50, the trader would lose $400 on the long
January 50 call and would make $100 on the short January 60 call. Ideally, the
trader would like to see the market rally. If Micron stock were trading at $50
per share, the trader would make nothing on the long Jan 50 call option
position that is at-the-money, lose nothing on the short Jan 60 call option
position that is out-of-the-money, and lose $300 for the fixed cost to initiate
the spread, for a net loss of $300. If Micron stock were trading at $53 per
share, the trader would make $300 on the long January 50 call option position
that is in-the-money, lose nothing on the short January 60 call option position
that is out-of-the-money, and lose $300 in nonrefundable costs to initiate the
spread, for a net gain of zero. If Micron stock were trading at $55 per share,
the trader would make $500 on the long January 50 call option position that is
in-the-money, lose nothing on the short January 60 call option position that is
out- of-the-money, and lose $300 in fixed costs necessary to initiate the
spread, for a net gain of $200. If Micron stock were trading at $60 per share,
the trader would make $1000 on the long January 50 call option position that is
in-the-money, lose nothing on the short January 60 call option position that is
at-the-money, and lose $300 for the fixed cost to initiate the spread, for a
net gain of $700. Finally, if Micron stock were trading at $65 per share, the
trader would make $1500 on the long January 50 call option position that is
in-the-money, lose $500 on the short January 60 call option position that is
in-the-money, and lose another $300 for the nonrefundable cost to initiate the
spread, for a net gain of $700. Please note that once both call options are
in-the-money, the maximum gains have been attained, as any profits in the long
call option are exactly offset by the losses in the short call option. Also, if
both calls are exercised when they are in-the-money, the long January 50 call
option allows the trader to purchase 100 shares of Micron stock at $50 per
share and the short January 60 call option obligates the trader to sell 100
shares of Micron stock at $60 per share.
To summarize, the most the trader could
lose in a long call spread would be the cost of the spread ($300), and the most
the trader could make in a long call spread would be the difference between the
two strike prices minus the cost of the spread ($1000 - $300 = $700). (See
Payoff Diagram 2.5.) This differs from
the case of a long January 50 call option alone, where the maximum loss is the
cost of the contract ($400) and the maximum gains are unlimited.
Selling a call spread. If a trader sells a call option, he or she is looking for
the market to decline so the option can expire out-of-the-money and he or she
can profit. Likewise, a short call spread can be initiated to anticipate
bearish market conditions. A short call spread entails the sale of a call
option with one strike price and the simultaneous purchase of the same call
option with a higher strike price. Ultimately, when selling a call spread, the
trader wants both calls to expire out-of- the-money. With call options, the
lower the strike price, the greater the premium. Therefore, at the time the
short call spread is initiated, the premium that the trader receives for the
call option with the lower strike price will be greater than the premium that
the trader pays for the call option with the higher strike price. Since the
trader receives a greater premium by selling a call option than what he or she
must pay for the long call option, the net premium cost is more than offset in
a bear call spread. Because the trader receives money upon initiating the
trade, this is considered a credit spread. To obtain the break-even point of a
short call spread, one would add the net premium received on the spread to the
short call option’s strike price (the lower strike price)—anything below this
break-even point would be a gain on the trade and anything above this
break-even point would be a loss on the trade.
The advantage of selling a call spread
is that it offers less risk than if one were to simply sell a call option
outright. Initiating a short call spread provides immediate income to the
option writer, although it is less than the amount the trader would have
received had he or she simply sold the call option outright. By purchasing a
call option with a higher strike price, the trader receives some added
protection, thereby creating a finite, as opposed to an unlimited, level of
risk. The most one can lose on the trade is capped at the difference between
the two call option strike prices minus the total premium received on the
spread. However, the drawback is that the maximum gains are defined at the
outset of the trade as simply the total (net) premium received on the spread.
If both options of a short call spread were to

expire out-of-the-money, then the
trader would retain the greater price received for the short call option
position with the lower strike price, and would lose the lesser price paid for
the long call position with the higher strike price. In any case, with a short
call spread, the potential gains are less than the potential losses:
Example
Sell 1 Micron (MU) Jan 50 Call @ 4
Buy 1 Micron (MU) Jan 60 Call @ 1
Market price of Micron stock: $50
In this example, the trader has
initiated a short call spread. This trader has sold one Micron call option with
a January expiration and a $50 strike price for $400 and has purchased one
Micron call option with a January expiration and a $60 strike price for $100,
when Micron is trading at $50 per share. Therefore, the total premium received
by the trader for the spread is $300. This is a nonrefundable, fixed income
payment to the trader and cannot be lost. This $300 is also the most a trader
can gain on the transaction—if both calls were to expire out-of-the-money,
meaning Micron stock were trading at any price below $50, the trader would gain
$400 on the short January 50 call and would lose $100 on the long January 60
call. Therefore, the trader would ideally like to see the market decline. If
Micron stock were trading at $50 per share, the trader would lose nothing on
the short January 50 call option position that is at-the-money, make nothing on
the long January 60 call option position that is out-of-the-money, and make
$300 for the fixed payment to initiate the spread, for a net gain of $300. If
Micron stock were trading at $53 per share, the trader would lose $300 on the
short January 50 call option position that is in-the-money, make nothing on the
long January 60 call option position that is out-of- the-money, and make $300
for the nonrefundable payment to initiate the spread, for a net gain of zero.
If Micron stock were trading at $55 per share, the trader would lose $500 on
the short January 50 call option position that is in-the-money, make nothing on
the long January 60 call option position that is out-of-the-money, and make
$300 for the fixed payment that was necessary to initiate the spread, for a net
loss of $200. If Micron stock were trading at $60 per share, the trader would
lose $1000 on the short January 50 call option position that is in-the-money,
make nothing on the long January 60 call option position that is at-the-money,
and make $300 for the fixed payment to initiate the spread, for a net loss of
$700. Finally, if Micron stock were trading at $65 per share, the trader would
lose $ 1500 on the short January 50 call option position that is in-the-money,
make $500 on the long January 60 call option position that is in-the-money, and
make another $300 for the nonrefundable payment necessary to initiate the
spread, for a net loss of $700. Please note that once both call options are
in-the-money, the maximum losses have been attained, as losses in the short
call option are exactly offset by the profits in the long call option. Also, if
both calls are exercised when they are in-the-money, the short January 50 call
option obligates the trader to sell 100 shares of Micron stock at $50 per share
and the long January 60 call option allows the trader to purchase 100 shares of
Micron stock at $60 per share.
To summarize, the most the trader could
make in a short call spread would be the payment received for the spread ($300)
and the most the trader could lose in a short call spread would be the difference
between the two strike prices minus the payment received for the spread ($1000
- $300 = $700). (See Payoff Diagram 2.6.) This differs from the case of a short
January 50 call option alone, where the maximum gain is the payment received
for the contract ($400) and the maximum losses are unlimited.
Buying a put spread. If a trader purchases a put option, the trader is looking
for the market to decline so the option can expire in-the-money and he or she
can profit. Likewise, a long put spread can be initiated to anticipate bearish
market conditions. A long put spread requires the purchase of a put option with
one strike price and the simultaneous sale of the same put option with a lower
strike price. Ultimately, when buying a put spread, the trader wants both put
options to expire in-the-money. With put options, the higher the strike price,
the greater the premium. Therefore, at the time the long put spread is
initiated, the premium that the trader pays for the put option with the higher
strike price will be greater than the premium that the trader receives for the
put option with the lower strike price. Since the trader must pay a greater
premium for the rights to the long put option than what he or she receives for
the short put option, the net premium cost is partially offset in a bear put
spread. Because the trader must put up the necessary funds upon initiating the
trade, this is considered a debit spread. To obtain the break-even point of a
long put spread, one would subtract the net cost of the spread from the long
put option’s strike price (the higher strike price)—anything below this
break-even point would be a gain on the trade and anything above this breakeven
point would be a loss on the trade.
The advantage of buying a put spread is
that it provides less risk than if one were to simply purchase a put option
outright. The most one can lose on the trade is the total cost (net premium
cost) of the spread—if both options of a long put spread were to expire
out-of-the-money, then the trader would lose the greater price paid for the
long put option position with the higher strike price, and would retain the
lesser price received for the short put position with the lower strike price.
By selling a put option with a lower strike price, the trader receives additional
income, thereby reducing the total cost of the spread and the maximum possible
loss. However, the drawback is that gains are also limited. This maximum gain
is capped at the difference between the two put option strike prices minus the
total cost (net premium cost) of the spread. In any case, with a long put
spread, the potential gains are greater than the potential losses.

Example
Buy 1 Micron (MU) Jan 60 Put @ 4
Sell 1 Micron (MU) Jan 50 Put @ 1
Market price of Micron stock: $60
In this example, the trader has
initiated a long put spread. He or she has purchased one Micron put option with
a January expiration and a $60 strike price for $400 and has sold one Micron
put option with a January expiration and a $50 strike price for $100, when
Micron is trading at $60 per share. Therefore, the total cost of the spread is
$300. This payment is a nonrefundable, fixed cost to the trader and cannot be
retrieved. This $300 is also the most a trader can lose on the transaction—if
both puts were to expire out-of-the-money, meaning Micron stock were trading at
any price above $60, the trader would lose $400 on the long January 60 put and
would make $ 100 on the short January 50 put. Ideally, the trader would like to
see the market decline. If Micron stock were trading at $60 per share, the
trader would make nothing on the long Jan 60 put option position that is
at-the-money, lose nothing on the short Jan 50 put option position that is
out-of-the-money, and lose $300 for the fixed cost to initiate the spread, for
a total loss of $300. If Micron stock were trading at $57 per share, the trader
would make $300 on the long Jan 60 put option position that is in-the-money,
lose nothing on the short Jan 50 put option position that is out-of-the-money, and
lose $300 in nonrefundable costs to initiate the spread, for a net gain of
zero. If Micron stock were trading at $55 per share, the trader would make $500
on the long Jan 60 put option position that is in-the- money, lose nothing on
the short Jan 50 put option position that is out-of-the- money, and lose $300
in fixed costs necessary to initiate the spread, for a net gain of $200. If
Micron stock were trading at $50 per share, the trader would make $1000 on the
long Jan 60 put option position that is in-the-money, lose nothing on the short
Jan 50 put option position that is at-the-money, and lose $300 for the fixed
cost to initiate the spread, for a net gain of $700. Finally, if Micron stock
were trading at $45 per share, the trader would make $ 1500 on the long Jan 60
put option position that is in-the-money, lose $500 on the short Jan 50 put
option position that is in-the-money, and lose another $300 for the
nonrefundable cost to initiate the spread, for a net gain of $700. Please note
that once both put options are in-the- money the maximum gains have been
attained, as any profits in the long put option are exactly offset by the
losses in the short put option. Also, if both puts are exercised when they are
in-the-money, the long Jan 60 put option allows the trader to sell 100 shares
of Micron stock at $60 per share and the short Jan 50 put option obligates the
trader to purchase 100 shares of Micron stock at $50 per share.
To summarize, the most the trader could
lose in a long put spread would be the cost of the spread ($300) and the most
the trader could make in a long put spread would be the difference between the
two strike prices minus the cost of the spread ($1,000 - $300 = $700). (See
Payoff Diagram 2.7.) This differs from the case of a long Jan 60 put option
alone, where the maximum loss is the cost of the contract ($400) and the
maximum gains are the total value of the underlying contract if it were to
decline to zero ($6000 - $400 = $5600).
Selling a put spread. If a trader sells a put option, he or she is looking for
the market to rally so the option can expire out-of-the-money and he or she can
profit. Likewise, a short put spread can be initiated to anticipate bullish market
conditions. A short put spread entails the sale of a put option with one strike
price and the simultaneous purchase of the same put option with a lower strike
price. Ultimately, when selling a put spread, the trader wants both puts to
expire out-of-the- money. With put options, the higher the strike price the
greater the premium. Therefore, at the time the short put spread is initiated,
the premium that the trader receives for the put option with the higher strike
price will be greater than the premium that the trader pays for the put option
with the lower strike price. Since the trader receives a greater premium by
selling a put option than what he or she must pay for the long put option, the
net premium cost is more than offset in a bull put spread. Because the trader
receives money upon initiating the trade, this is considered a credit spread.
To obtain the break-even point of a short put spread, one would subtract the
net cost of the spread from the short put option’s strike price (the higher
strike price)—anything above this break-even point would be a gain on the trade
and anything below this break-even point would be a loss on the trade.
The advantage of selling a put spread
is that it offers less risk than if one were to simply sell a put option
outright. Initiating a short put spread provides immediate income to the option
writer, although it is less than the amount the trader would have received had
he or she simply sold the put option outright. Also, by purchasing a put option
with a lower strike price, the trader receives some added protection, thereby
creating a finite (as opposed to an unlimited) level of risk. The most one can
lose on the trade is capped at the difference between the two put option strike
prices minus the total premium received on the spread. However, the drawback is
that the maximum gains are defined at the outset of the trade as simply the
total (net) premium received on the spread. If both options of a short put
spread were to expire out-of-the-money, then the trader would retain the
greater price received for the short put option position with the higher strike
price, and would lose the lesser price paid for the long put position with the
lower strike price. In any case, with a short put spread, the potential gains
are less than the potential losses.

2.7. Profit diagrams for a long put spread and the Micron long put spread example.
In this example, the trader has
initiated a short put spread. The trader has sold one Micron put option with a
January expiration and a $60 strike price for $400 and has purchased one Micron
put option with a January expiration and a $50 strike price for $100, when
Micron is trading at $60 per share. Therefore, the total premium received by
the trader for the spread is $300. This is a nonrefundable, fixed income
payment to the trader and cannot be lost. This $300 is also the most a trader
can gain on the transaction—if both puts were to expire out-of-the-money,
meaning Micron stock were trading at any price above $60, the trader would gain
$400 on the short January 60 put and would lose $100 on the long January 50
put. Therefore, the trader would ideally like to see the market rally. If
Micron stock were trading at $60 per share, the trader would lose nothing on
the short Jan 60 put option position that is at-the-money, make nothing on the
long Jan 50 put option position that is out-of-the-money, and make $300 for the
fixed payment to initiate the spread, for a net gain of $300. If Micron stock
were trading at $57 per share, the trader would lose $300 on the short Jan 60 put
option position that is in-the-money, make nothing on the long Jan 50 put
option position that is out-of-the-money, and make $300 for the nonrefundable
payment to initiate the spread, for a net gain of zero. If Micron stock were
trading at $55 per share, the trader would lose $500 on the short Jan 60 put
option position that is in-the-money, make nothing on the long Jan 50 put
option position that is out-of-the-money, and make $300 for the fixed payment
that was necessary to initiate the spread, for a net loss of $200. If Micron
stock were trading at $50 per share, the trader would lose $1000 on the short
Jan 60 put option position that is in-the-money, make nothing on the long Jan
50 put option position that is at-the-money, and make $300 for the fixed payment
to initiate the spread, for a net loss of $700. Finally, if Micron stock were
trading at $45 per share, the trader would lose $1500 on the short Jan 60 put
option position that is in-the-money, make $500 on the long Jan 50 put option
position that is in-the- money, and make another $300 for the nonrefundable
payment necessary to initiate the spread, for a net loss of $700. Please note
that once both put options are in-the-money the maximum losses have been
attained, as losses in the short put option are exactly offset by the profits
in the long put option. Also, if both puts are exercised when they are
in-the-money, the short Jan 60 put option obligates the trader to purchase 100
shares of Micron stock at $60 per share and the long Jan 50 put option allows
the trader to sell 100 shares of Micron stock at $50 per share.
To summarize, the most the trader could
make in a short put spread would be the payment received for the spread ($300)
and the most the trader could lose in a short put spread would be the
difference between the two strike prices minus the payment received for the
spread ($1000 - $300 = $700). (See Payoff Diagram
2.8.) This differs from the case of a short put option where the
maximum gain is the payment received for the contract ($400) and the maximum
losses are the total value of the underlying contract if it were to decline to
zero ($6000 - $400 = $5600).
Calendar Spreads
The four types of spreads just
mentioned were vertical spreads, or price spreads. Another group of spreads is
referred to as horizontal spreads, time spreads, or calendar spreads. Whereas
vertical spreads are used to take advantage of price movements in the
underlying security, horizontal spreads are used to take advantage of time
erosion and the pricing discrepancies that arise from movements in the underlying
market. A horizontal spread involves the simultaneous purchase and sale of an
option contract of the same asset, type, and strike price but with different
expiration dates. As we indicated earlier, the option’s time value erodes
toward zero as time passes toward option expiration. The erosion occurs more
rapidly as the option’s life decreases and the expiration date comes into view.
A calendar spread is intended to take advantage of this decline in an option’s
premium. Typically, a trader will sell an option with the closer expiration
month and purchase an option with the distant expiration month to take
advantage of the fact that the latter position will retain more of its value.
Since the near-month option has less time to expiration than the back-month
option, the premium the trader receives will be less than the premium the
trader must pay for the spread. Therefore, this spread is considered a debit
spread. Also, because one option expires before the other, oftentimes one or
both legs of the calendar spread are offset by trading out of the position.
Example
Sell 1 Intel (INTC) Apr 120 Call @ 6
Buy 1 Intel (INTC) July 120 Call @ 10
Market price of Intel stock: $117
In this example, a trader has initiated
a short calendar spread. Here, he or she has sold one Intel call option with an
April expiration and a $120 strike price at a cost of $600 and has purchased
one Intel call option with a July expiration and a $120 strike price at a cost
of $1000. Therefore, the net cost to initiate the spread is $400. By selling
the April 120 call option, a trader is hoping that the market will move
sideways into expiration so that a profit can be realized coincident with the
erosion in the time premium. However, to protect him- or herself in the case of
an adverse price move, the trader hedges his or her position by purchasing the
July 120 call option. This way, if the market were to rally and the trader’s
short option position were exercised, obligating the trader to sell 100 shares
of Intel stock to the option holder at $120 per share, the trader could in turn
exercise the long option position to purchase 100 shares of Intel stock at $120
per share. If the market were to move sideways as the trader had hoped, the
short option contract would lose much more of its premium value than the long
option contract. For example, say that on the April option expiration date both
calls are still trading at $117 per share (out-of-the-money) with the new
premium for the April 120 call falling to zero and the new premium for the July
120 call falling to $6/4. By trading out of the spread

at these prices (by taking the opposite
side of each option), the trader would make $600 by selling the April call at
$600 and purchasing it at $0 and would lose $350 by purchasing the July call at
$1000 and selling it at $650, for a net gain of $250. In this case, the trader
could exit the trade with a profit.
Example
Sell 1 Intel (INTC) Apr 120 Put @ 6
Buy 1 Intel (INTC) July 120 Put @10
Market price of Intel stock: $123
In this scenario, the trader has again
initiated a short calendar spread. Here, the trader has sold one Intel put
option with an April expiration and a $120 strike price at a cost of $600 and
has purchased one Intel put option with a July expiration and a $120 strike
price at a cost of $1000. Therefore, the net cost to initiate the spread is
$400. By selling the April 120 put option, the trader is hoping that the market
will move sideways into expiration so that a profit can be realized coincident
with the erosion in the time premium. However, to protect him- or herself in
the case of an adverse price move, the trader hedges his or her position by
purchasing the July 120 put option. This way, if the market were to decline and
the trader’s short option position were exercised, obligating the trader to
purchase 100 shares of Intel stock from the option holder at $120 per share,
the trader could in turn exercise the long option position to sell 100 shares
of Intel stock at $120 per share. If the market were to move sideways as the
trader had hoped, the short option contract would lose much more of its premium
value than the long option contract. For example, say that on the April option
expiration date both puts are still trading at $123 per share
(out-of-the-money) with the new premium for the April 120 put falling to zero
and the new premium for the July 120 put falling to $6/2. By trading out of the
spread at these prices (by taking the opposite side of each option), the trader
would make $600 by selling the April put at $600 and purchasing it at $0 and
would lose $350 by purchasing the July put at $1000 and selling it at $650, for
a net gain of $250. In this case, the trader could exit the trade with a
profit.
Diagonal spreads work in the same
manner as vertical and horizontal spreads and are simply a combination of the
two.
