Trading System Resources
Welcome to trading. A new
investor has to be impressed by so many paths to trading the markets. He can either learn a trading system from a
master trader, follow an advisor or go it alone. The most independent of
us attempt to go it alone, at first. Initially we just look for good
stocks that will eventually rise in price. But too soon we learn that,
even with the best stocks, prices move downward for periods of time, as well as,
up. Often the downward movement is faster than the grinding upward
progress previously made. So time seems to have been lost. At this
point we risk falling into the trap of focusing too heavily on short term gains.
Watching price behavior, an independent trader senses a
need for timing his trade entry and exit points. Now, perhaps, he is
willing to track an advisory that instructs him on when to buy and sell.
Since he is independent by nature, he typically uses the advisory information as a
reference only and doesn't follow it to the letter. After all he reasons, he has a 50%
chance of being right, doesn't he? I mean, a stock can only go either up
or down, right? After making a series of ill timed entries and
exits, only partially following an advisor due to less than full confidence, he realizes that he is not
much better off than he was before. Advisors, he reasons, only tell him
what to do but not how to make decisions for himself. After all, he
reasons, that's how they make a
living and they don't want to put themselves out of business. So his
results seldom match those of the advisor's portfolio.
Eventually our independent trader arrives at a point
where he realizes that in order to be both independent and successful, he needs to
specialize in at least one good trading system. "But this sounds
expensive", he thinks. "Don't I have to add a lot of additional hardware
and software to get a good trading system?". The answer is, not
necessarily. A trading
system consists of a set of rules for viewing markets and making trades. The
advantages of trading systems can be hidden when they become associated with
trading platforms involving trade order submission and processing. A
clarification of their roles can help explain the benefits of using a trading
system. This can be done without identifying a particular platform or system.
Once the platform infrastructure is isolated, a brief look can be taken at why a
trader can benefit from a trading system.
An online trading
platform consists of the infrastructure for viewing market prices and making
trades. While platforms make use of user provided hardware and the internet
itself, platforms consist of software linked to a database while displaying
price quotes, enabling order entry and routing orders to an exchange. A
platform of software and order routing services is provided by many brokers. It
often includes programmable charting software that allows a user to select from
an array of formats for price, volume and technical indicators. Links to real
time databases are used by day traders while free delayed quotes are quite
adequate for position traders who analyze data after the markets close to
minimize the emotional stress of changing prices. Platform software saves time
and reduces errors by automating repetitive tasks.
Some platform tools have
become quite sophisticated, allowing a user to add his personal rules.
Advisory software systems
use these rules to advise the user when to make trades. Rules tell the software which set of indicators and prices to monitor
and the levels at which traded instruments are to be bought and sold.
Automated
systems trading software are preprogrammed with trading rules enabling them to
make trades with minimal user input. These software modules, designed by third
party vendors to operate under existing platforms, are based on algorithms that
identify price trends and market turning points. Since their accuracy is limited
by the presumed market volatility, an algorithm is needed to recognize when
market volatility falls outside the envelope for which the software rules were
designed. The quality of a set of rules can be estimated from historical back
testing on past market prices stored in a database. It is often pointed out
that back testing lacks the realism of real time emotional stress and that past
performance is not an indicator of future performance. While the latter is
valid in all cases, the nature of trading system rules reduces emotional stress
to the degree that the rules are consistently followed.
In any case, it is the
rules themselves that comprise the trading system. In their purest form, trading
systems take the form of a compact set of rules written on paper. These
are referred to here as
procedural rule based trading systems.
The ability to
consistently make error free decisions amid changing prices in an environment of
fear and greed is unlikely without the discipline that rules provide. It does
little good to have all the price monitoring, charting, order submission and
routing infrastructure if one does not have a consistent set of rules for making
trades. Most of us find this out the hard way, judging from the statistic that
only about 12% of stock traders are successful. For futures traders the number
is closer to 5%. It is not just a coincidence that the percentage of traders
that rely on a proven trading system is near these same levels. The consistent
use of a proven trading system can be most beneficial to traders with all levels
of experience.
Seeing the
difference between trading systems and platform infrastructure makes the
characteristics of a good trading system more obvious. A good trading system
explains when trading should not be attempted, thereby, avoiding forced trading
under inopportune conditions. It should specify how to independently generate a
strong watch list of candidate trades to eliminate the need to chase after the
latest hot tip from an advisor. For obvious reasons, a trading system should be
easy to use, totally objective, take little of a trader’s time and make
consistent profits. It should also avoid large draw downs and give clear
trading signals. Once a trading system is
consistently in use, extraordinary opportunities for setting and meeting
realistic profit goals become available by using a model of
precision money management.
A trading system is best
learned from a master trader who remains actively engaged in teaching. The
master can help the student tailor the system to his personality, financial
means, risk tolerance and skill level. The next best approach is to simply read
what has been written and adopt it to one’s personal situation. But under no
circumstances should one try to wing it without the support of a set of trading
rules. The advantage of rule based trading systems lies in their objectivity
and consistency. When followed consistently, emotional trading and its
associated errors are removed from the equation. As an investment, trading
systems more than pay for themselves, not only in profits gained, but also in
the amount of capital preserved. This is true not only for advanced automated
trading systems but also for a compact set of rules on paper. See our
comprehensive list of available
trading systems.
