Background

This week we begin the first of a three-part series on specific order strategies to take
advantage of rolling stocks. Our first deals with the mechanics of placing orders with
internet brokers (and some full-service tips as well). We will cover Market, Limit & Stop
orders, how they can be combined, some red-flags to consider, how they are timed, and how
your intestment style is factored in. Next week we will put them into action on current
tickers showing how to investigate their value with paper trades, and the last segment
covers the "So what?" What does it all mean to our investment ACTIONS!
If we could sit at a terminal all day with a direct connection to the floor of the market,
carefully watching price movements, we wouldn't need special orders. We could take action
as required. However, they become an important tool to help us execute strategies, to
maximize timing, and to rid us of the task to monitor market activity continually. Additionally,
they help us keep emotion from clouding many of our investment decisions.
To make them work for us, we need to understand what they can and cannot do. So, let's consider
these issues now.
There are three basic types of orders; market, limit and stop.
- Market - An order for the broker to immediately buy or sell at the next available
trade. A market order guarantees execution but not a specific price. This is the simplest
order for the broker to execute and may cost less, particularly with internet brokers.
When we place a market order, we do not know the exact price. We've instructed our broker
to act now to get the best buy or sell price available at the moment. We use this to sell
a stock as soon as possible. This order will be executed at the available price at the time
the order is received in the marketplace.
- Limit - A price limit is specified, instructing our broker exactly where to buy
or sell when the price is available. If the stock price does not become available at our
limit price, the transaction will not be executed.
Limit orders guarantee a price but not an execution. We place a limit on the amount we are
willing to pay to buy a stock or the amount we are willing to accept to sell the stock.
- Stop - A slight twist to the limit order is the Stop. This order, like the limit,
will be executed only when the specified price has been reached. The difference, however, is
that the stop becomes a market order when the stop price has been reached. The stop order is
then a conditional market order. The action will be to buy at the lowest available price or
to sell at the highest available price. This does not ensure the transaction will be made at
the stop price.
Stop or limit orders can be used to buy or to sell. The chart below shows how they work.

In this figure we see four different plays we can direct our broker to execute without any
further direction from us.
- Buy stop - If the price rises to $20, a market order is executed to buy
the stock at the best price available. This may be at, above or below $20. [We buy when
the price rises to our target] A buy-stop is always set above the market price.
- Sell stop - If the price falls to $10, a market order is executed to
sell the stock at the best price available. If the price gaps down dramatically the sell
price may be well below $10. In either case, buy-stop or sell-stop, the order will
be executed. [We sell when the price falls to our target] A sell-stop is
always set below the market price.
- Buy limit - If the price falls to $10, a limit order is placed to
buy the stock at $10 if it is available. If the order is executed, we
will get the stock at the limit price of $10. [We buy when the price falls to
our target] This order is placed below the market price.
- Sell limit - If the price rises to $20, the stock will be sold at $20
if a buyer can be found. [We sell when the price rises to
our target] A sell-limit is placed above market.
When would we use any of these?
- Buy-stop: If we want to buy a stock that looks near its bottom, we can set a buy-stop
at some level above the current price and buy in when it starts back up.
- Sell-stop: We bought U.S. Steel (X) at $24 and it has gone up to $28. We think it is
headed lower so we place a sell-stop at $27 to protect most of our profit. If the price
hits $27, the sell-stop will trigger a market order for the next available price. It could
be lower than $27. The play is called a Stop-loss, telling your broker
to sell if the price falls to a certain level, in order to prevent further losses. This
provides a degree of profit protection.
- Buy-limit: We place a buy-limit order if the stock we want to buy is likely going
lower. Here the broker will buy only when the price falls to the value we've named.
- Sell-limit: Similarly, if we own a stock that's rising in value, we can place a limit
order to sell only if and when it climbs to the pre-established price.
Caveats: For each of these four plays there are dangers to consider:
- Buy-stop: A problem with all stop orders is they do not guarantee the execution
price. If a stock spikes up, the buy trigger kicks in but by the time our order is filled
the price may be much higher than we intended to pay.
- Sell-stop: This play is called a stop-loss and we could suffer from what is called
"whipsawing," (or being whipsawed). This is a rapid price movement followed by a sharp
change in the opposite direction. We place a sell-stop order and it kicks us out of a
stock at a certain price, then the stock immediately goes back up in price. We can get
dizzy trying to chase a stock in these cases. Careful selection of the stop price becomes
important to minimize this possibility. That is, we must use wisdom in deciding how far
from the current price to place the stop. This of course depends on the volatility of the
selected stock. Similar to the buy-stop above, if the stock gaps down, by the time our
order is filled we may sell for a lot less than we planned.
- Buy-limit: While the intent here is to buy into a better position on a stock, having
the broker buy when the price falls to some target can be counter to reason. While the
stock is going down, that may be the wrong time to buy.
- Sell-limit: Similarly, to sell when the stock is on the rise may sound at odds with
reason. There are occasions when it is prudent to sell into strength, with the stock on
the rise, but a lot depends on particular objectives. With rollers we may suffer some
disappointments selling with the stock on an up-tick. The next editorial deals with this
specific issue with methods to minimize this problem.
To reduce the uncertainty of a stop order, a Stop-Limit has been designed
(a combination of the stop and limit orders). Here, we specify not one but two prices:
a stop price and a limit price. This tells the broker to buy or sell at a specified price
or within a specified range.
When the stock price reaches the stop price, then a limit order is created
at the limit price. Hence, a stop-limit order is a conditional limit
order (also called a trailing-stop). It becomes a limit order only
when the stop price is surpassed. Like a stop, a
stop-limit begins to execute once the stop price is reached. Rather than selling at market
price, however, it will be sold at any price down to the limit. When (if) executed the sale
price will be in a range between the stop and limit. This helps prevent selling off at a
lower than expected price when the market is quite volatile.
Let's demonstrate with a graphic where a "sell at $6 stop, $5 limit" stop-limit order has
been placed. If the stock drops to the stop price ($6), the stop-limit is invoked and
the stock is offered for sale at that price. However, if the price drops below the limit
price ($5), the lower limit is exceeded, and the execution is
halted. We are telling the broker we want out at $6, but not less than $5.

A $6 limit order would fill only if the $6 price were available. A stop-limit as described
will fill if any price between $5 and $6 is available. We can see why the stop-limit will
more likely be filled than the limit. This is how we reduce the uncertainty.
A stop-limit order with some internet brokers requires the stop and the limit be set at
the same price (they do not allow "trailing stops"). This would look like "sell at $6
stop, $6 limit" which means "I want out
at $6 and not less than $6." This becomes then simply a limit order. A quick poll last
week found two on-line brokers who require the stop & limit be set at the same price,
five allow different prices. When allowed, both the stop and limit price must be set
below market for a sell, and above market for a buy. The on-line broker may require
that stop-limit orders be placed on the telephone. Be sure you find out the rules for
your own broker.
These special orders can be helpful for both buy and sell transactions. When we are unable
to watch price movements in the market continuously, special orders can keep us honest with
our entry and exit strategies. For instance, emotions can thwart a sound strategy as we
hesitate, should we sell now or wait for the next small uptick? Should we buy now or wait
for a few more cents drop? These orders become the "enforcers!"
Timing: Whenever we place an order, we must specify whether we want the order to
be good for that day only or until we fill or cancel. Four order types are available:
- Day: A day order is just that, it simply expires at the close of trading
on the day it was entered. All market orders are day orders.
- Good until cancelled (GTC): The orders herein considered require time
for prices to advance or decline. To keep the order active for many days or weeks, we use
the GTC. Check with your own broker to see how long they will allow a GTC order to remain
active. 60 days is common but may be more or less. Red Flag: If a GTC order is filled
over several days when there are not enough shares available to fill at once, we get
charged a commission on each day's transaction.
- All or none (AON): To prevent the problem noted with GTC multiple
commissions, we can specify the order is to be executed only if all the shares can be
executed at once. Red Flag: Placing a condition on the order may prevent us
from buying the stock. AON are low priority orders.
- One cancels the other (OCO): This order tells the broker to execute only
one of two possible transactions. For instance, if we want to sell when the price rises to
$12 but protect our downside with a stop at $4, we place a sell-limit at $12 and a
stop-loss at $4. The first order to occur will cancel the other automatically. When
this option is available, some creative stop/limit combinations are possible. Internet
brokers do not usually provide this order type. Their computer systems will
not accept two orders for the same stock. The danger is the first part of the order may
sell the stock, then the second order could be triggered with no shares in the account.
One broker would accept such an order with the understanding (written &
documented) that I was responsible for selling short if it came to that. Other responses
have said simply, "not allowed in our industry!"
A full service broker handles this transaction
manually, canceling the other when the first order fills. That is some of the service we
pay for in an FSB.
Style: The use of special orders becomes in large part a matter of style. That is,
the orders to use depend on specific strategy. For instance, consider the two extremes
of the market sandbox, Long Term Buy & Hold and Day (short-term) Trading:
- Buy & hold strategists will tell us to use market rather than limit orders in most cases.
Rather, identify stocks with good fundamentals & positive technical signals and the stock
price should be moving steadily higher. A limit places unnecessary conditions on a
purchase, like "don't pay more than $42, etc." Nitpicking over fractions of a point
may keep us out of a good stock.
- A short-term trader will usually stick with limit orders, defining the exact price
for an execution. I've heard them refer to market orders as a license to steal!
Next week we will put all these strategies to work on real price charts, helping us understand
which to use where, and when.
Understanding:
It is
our intent to help our readers understand market strategies well enough
to make informed
decisions and to know the risks.
We provide TC2000 tutorials to members
upon request.
