Article:Thinking In Probabilities
by Larry Pesavento
It is a given that traders can not win 100 percent of the time, because with
reward comes risk, and losses are as much a fact of life as taxes and death.
But
there are highly valuable lessons to be learned about the trading process that
go far beyond dollar signs. How traders put reliable steps in place to ensure
that their performance may be enhanced on the road to success is dependent not
only on what is done correctly but also on what potentially havoc-wreaking
mistakes can be avoided.
The three practical principals that can aid in anticipating and, possible,
avoiding mistakes are probability, self-discipline and responsibility
– simple enough to write, but harder to carry out.
No successful trader would deny that mental preparation is just as necessary
as charts and market signals. Trading is all about probabilities and, while
every trader encounters a losing streak or draw down of equity, success as a
trader is measured by how well losses are handled mentally.
A "sure" sign of potential disaster is holding large losses in open
positions while at the same time taking many small profits. This is contrary to
the market adage by a wise trader/mentor from Commodity Corporation, Amos Barr
Hostetter, who said, "Take care of your losses and your profits will take
care of themselves." A trader who mentally dupes himself into believing
that the small profits will offset the large losses is taking a dangerous
ostrich approach.
Most losing streaks are the result of probability distribution. In 100
trades, a system should encounter a losing streak of up to eight trades in a
row, and this is the time when the trader begins to question the validity of the
system. It also normally is the worst time to stop trading as long as the trader
has followed his methodology, because it’s been shown that winning streaks
generally follow losing streaks.
Examining daily trading logs enables the trader to spot some common trading
mistakes such as lack of discipline, sloppiness in trade preparation, impulse
trading, impatience, and all of the other cousins and uncles in the
"mistake family." One of the big advantages of the pattern recognition
method of swing trading is the probability associated with each pattern. Winning
is a matter of executing all of the trades as the patterns develop.
Traders must train themselves to think in terms of probability for three very
important reasons:
- No one knows with 100-percent certainty whether the trade will be
profitable or not.
- No one knows how much money will be made or lost on a trade.
- If the trader does not control the profit outcome and does not know with
100-percent certainty which trades will work, then the trader should spend
100-percent of his time concentrating on the only element of the trade he can
control – the risk of the trade.
Key to success is the ability to pinpoint how much one can afford to lose.
Winners think "how much can I lose?" while losers think "how much
can I win?" This fact is easy to demonstrate. Anyone visiting Las Vegas –
has been greeted by brightly colored, flashing slot machines that beckon the
full-pocketed tourist with the promise "Win One Million Dollars!"
However, no visitor has ever seen a sign that reads, "This machine has
taken in three million dollars this year." When the trader truly learns how
to think like the "house", the probability of winning is increased.
Thinking about losing requires discipline. By focusing acutely on a trading
plan, the probabilities for profits or losses and streaks of each, and risk
control, risk-taking becomes more manageable and can give traders the ultimate
gift – freedom. In fact, making discipline a daily habit allows traders
"to weave a habit of a strand a day of discipline until the cable of
discipline is almost unbreakable."
Discipline in trading presents itself in several parts. First, there is
preparation. Trading is simple, but it takes time. Many hours of preparation
occur long before any trade is entered. These steps include:
Mental – Traders must think through what risks are present in the
trade, and know in advance how to get out of the trade and at what point. Mental
preparation, from my experience, also assumes eliminating or limiting alcohol
consumption from Sunday through Thursday of the trading week, because it
typically takes up to 24 hours to completely leave the blood system. It’s best
to have the brain working at an optimal level.
Technical – Methodologies vary by the individual trader. All trading
opportunities should be explored. A daily ritual of scanning charts will present
many good opportunities. This is the time-consuming part of trading.
Opportunities, however, do not guarantee profits.
Physical – Traders need to release tension in a positive way. Take time
to do some type of exercise like golf, tennis or walking.
Discipline is also necessary on the execution side of trading. Risk control
is the most critical element of the tracing process. Never forget how a
devastating loss can destroy the ‘psyche." It damages the trader’s
soul.
Monitoring a profitable trade in progress also requires discipline – follow
the trading plan. Do not be concerned about minuscule fluctuations if your goal
is higher. There are two questions that every trader should ask: "Has the
market changed since I placed the trade? Can I afford the risk on this
trade?" If the answer to both of these questions is "yes" the
trader should stay in the trade.
Along with discipline, responsibility plays a significant role in the trading
game. Once in the market, the trader alone has responsibility for his or her
trading decisions – no one else. Not assuming personal responsibility is like
jumping into a fast-moving river without a life jacket in the hopes that there
is a lifeguard somewhere on the shore. The trader can keep afloat only if he is
responsible for his own destiny. Take joy in the good decisions and learn from
the bad ones. Place the orders, close the orders and take the profits.
Or,
swallow hard, and take the loss if that’s the responsible thing to do and your
plan points in that direction.
Traders can and do fall into the habit of making excuses about why something
went wrong. Again quoting Hostetter, "Forget your profits, but forget you
losses faster."
Taking responsibility can be improved by including a few steps or reminders
in the trading plan. What works for one trader might not work for another.
The
way to handle this is to place a written statement on the computer. The
statement says: Has the pattern in the trade changed from the original pattern?
Has the initial price objective been reached?
If the answer to both of these questions is "yes" its time to exit
the trade. If the answer is "no" then the trade must continue; trading
is a business of dealing with probabilities, not certainties. Hostetter
held that, "We never know which trades will work; the problem arises when
we only ‘think’ we know."
Probability, discipline and responsibility are traits that every trader
should strive to attain. Probability assures that losing streaks will develop
just as winning streaks will. What matters are how to recover from those losses.
Discipline and responsibility help to prevent devastating losses and aid in
recovery. Have the discipline to exit or stay in a trade, and take
responsibility for the actions. Again, losses are not 100 percent preventable,
however, with the right trading strategies and mental focus, many may be
avoided.

A popular chat room that follows the CCI study on 3-minute charts
uses these properties for Ensign Windows.

The colors and the line styles used by the Regular Divergence, the Hidden
Divergence and the Trend Lines are set using the 6 lines shown in the next
image. Change the Study Mode to be Rising..Falling so the 6 rows show as
in the following image. The top two rows are used by Regular Divergence
lines. The middle two rows are used by the Hidden Divergence lines.
The bottom two rows are used by the Trend Lines. So my Trend Lines
are dotted black lines. If you use a black background you would
obviously need to select a non-black color for your trend lines. The
divergence and trend lines are optional and show when their check boxes are
checked.
After setting the colors and lines styles for the divergence and trend lines, change the Study Mode back to
the mode you prefer, such as to Standard. The regular divergence, hidden
divergence and trend lines are automatically drawn as illustrated in this example.
