September 2001Research Tip:
Trading System Design by Howard Arrington
This issue of the Trading Tips newsletter will focus on
Trading Systems. Let's begin by discussing principles
that should be considered in designing a successful trading
system.
Emotion: Mechanical systems do not have emotion or
intuition, which can be both an advantage and a penalty.
Perhaps emotion control is the primary reason traders want to find a
successful trading system. How many times have you found
yourself mentally chiding yourself for not trading a signal or
formation when it was seen? The mental tug-of-war between fear
and greed can be debilitating. You find yourself willing to
concede 'pulling the trigger' to make the trade to the computer.
Emotion and intuition cannot be quantified mathematically, and
mathematics is all a trading system has to work with. So the
first and most fundamental principle in designing a trading system
is that every rule or reason for entering and exiting a
trade must be defined by mathematics.
Complexity: The second principle is the
KISS approach. (KISS means 'keep it stupid simple', or 'keep
it simple, stupid', which ever fits best.) A natural
tendency is to make the trading system too complex. A system
that initially started with a few rules, too often becomes too
complex when more rules are added to include or exclude special
situations. You need to be able to mentally understand and
remember the rules. If you cannot remember all the
rules, and immediately recognize the reason for the signal, then the
system is too complex.
Trading systems grow in complexity with the addition
of rules to consider more study values, blocking out certain times
of the day, skipping future signals based on recent bad performance,
and tweaking the system to handle special situations more
favorably. As a rule of thumb, I think the threshold for
having too many rules is around six.
Committee: The third principle is that a
trading system cannot be designed by a committee. Using a
committee sounds like an advantage, but it isn't. A
committee will never arrive at a consensus of opinion. The
debate about the appropriateness of every rule or parameter will
continue for months (probably without significant
progress). One reason for this is that every trader has
what I call a different 'risk avoidance threshold'. The
risk I personally am willing to take, and how long I am willing to
endure adversity, is completely different than the next
person. Everyone has a different financial situation,
personality, expectation, patience level and state of health.
If your last trade was a real winner, you might be overly confident
and greedy. If your last trade was a sizeable loss, you might
be dealing with fear and lack of confidence. Some traders want
to scalp and have lots of quick action. Others take a longer
view of trends. Some are unwilling to keep positions
overnight, while others are uncomfortable day trading.
So, in designing a trading system, design it to fit
you. Design it to make you a better trader and to
overcome your personal weaknesses. You will create a useful
trading system sooner and better by putting on blinders to the
opinions, suggestions, and 'wisdom' of all those who would tell you
what needs to be different about your system design to make them
happier.
Back Test: It is an absolute necessity
that you maintain a library of data sets that you can test your
trading system against. This library becomes a benchmark
against which every adjustment to your system can be
measured. New ideas will naturally happen during your
design process, and each new idea needs to be tested.
You are trying to answer the question of whether a new idea or rule
is beneficial. It goes without saying that the library must
include examples of all types of market conditions. It would
unwise to have a test library that is biased towards choppy markets,
or towards trending markets.
You want a trading system that thrives in the market
conditions it is designed for, and survives in all others. Not
every day will profitable. A successful system is one that
holds its own with minor losses offset by minor gains, and puts the
occasional great trades in the bank. If you expect
a system to be right all the time, or profitable every day, then you
will never find it, and probably abandon lots of ideas that had good
merit.
Optimization: Now let me offer a word of
caution about optimization. I was designing trading systems
back in 1987 when the markets experienced the October crash call
'Black Monday'. Optimization would have had any system
heavily short prior to the crash, ride it down, and then found a
signal that would have exited those short positions near the
bottom. Be very careful about optimizing for a special
situation.
I am not saying Black Monday should not have been
included in the library the system is tested against. What I
am saying is that it would be wrong to optimize a system to excel in
a Black Monday market, when that type of market movement only
happens a few times in one's life time. I really doubt
any system designed for Black Monday in 1987 was still being traded
in 2001 to benefit from the crash following the terrorist attack on
the United States. So, understand thoroughly what is being
optimized and how dependent the results are to special
situations. Special situations include large ranges,
lock limit moves, gap opens, and spikes.
With twenty years of experience in searching for the
'Holy Grail' of trading systems, I think I have probably 'been there
and done that'. I have not found the perfect system yet, and
my failure is not for a lack of trying or being a mental
lightweight. My final tip is to paper trade your system for
six months. If it holds up to your expectations over a
period of time, in all types of markets, then you can begin trading
it with real money. If your system didn't work out as
expected, then all you have lost is your time, but not your
money. I hope the experience shared in this article helps you
in your efforts to become a better trader and design a trading
system that works for you.
Research Tip:
Triangle Trading Program Developed by: James Baumann
Howard Arrington has stated before that there is no Holy
Grail. However, utilizing the power of ESPL and the
programming skills of Mike Lamont, I have developed a program that
has produced excellent trading results. This program has just
recently been completed after two years of development. The
live trade results have been nothing less then spectacular.
Back testing data from 1999 to the present, the program produced a
very high success rate on both a percentage basis and on a per trade
basis trading both sides of the market.
This multifaceted program serves as an irreplaceable trading tool
in all time frames. With the ease of the click of the user
study button the program will highlight buy and sell setups in a
visually easy way to recognize on any open chart in any time
frame. I can unequivocally state that the sell indicator has
saved me many times when no other studies would have helped warn of
impending doom. That function alone makes it a valuable
tool. This is just one of many benefits of the program.
I will not disclose the variables that identify the trading
setups. That is proprietary information. What I can do
is give a brief explanation of the capabilities of the program.
There are two major tools to be utilized by the trader. The
first is a scanning tool and the second is a back testing
tool. These tools can be used on individual charts that you
have open or you can use them on entire quote pages.
To scan an individual chart you click on the studies window and
click (1) for buy signals and click (2) for sell signals. Once a
trader is familiar with the patterns you will recognize safe trades
setups and uncertain setups. Get familiar with the price
action around these setups. It repeats itself over and over
again. The scan makes it easy to find the setups and sets the
price alert for you. The individual trader needs to learn the
normal nuances of stock price movements when the setup formations
occur. It is good to get a confirmation of the setup signal
with the use of your regular studies.
Setup Signal Description
When the Triangle Study is loaded on a chart it will color the
various buy and sell signals with five bars. For SHORT signals
the (A) green bar, the (B) blue bar, the (C) fuchsia bar and two
white confirmation bars. A short sell signal is generated when
prices trade below the low of the blue bar. The trader can be
aggressive and enter when prices first trade below the signal or you
can wait for prices to stop making new lows. Watch the
subsequent rally for 3 to 7 bars and wait for a bar to close counter
to the rally. That is a safe short entry point. Review
the examples shown in the next two charts.
SHORT SIGNAL EXAMPLE ON THE $INDU INDEX DAILY CHART
When tracking large numbers of stock symbols the quote page scan
tool is irreplaceable. You enter the name of the quote page
you want to search and the timeframe to search for the
signals. The program then scans all the symbols on the quote
page for buy and sell signals. You can also perform back
testing on quote pages. While scanning quote pages the user
has the option of having the program set a price alert or no
alert. This allows you to run the SCAN on the daily charts
with the alert activated. Alerts would then be set for any
daily signals. Next, when trading intra-day you can turn the
alert off. That allows you to use the scan tool on intra-day
charts without disturbing your daily alerts.
Once a buy or sell setup is found the individual stock symbol is
loaded into a new quote page named NEWBUYS or NEWSHORTS for easy
review without disturbing the custom quote page that was
scanned. When you run the scan the next time, if it finds a
new setup, it will load only the new stock symbol into the
NEWBUYS or NEWSHORTS quote page. At the same time, the program
saves all the quotes already reviewed from the previous scan into
another quote page named BUYS or SHORTS. When tracking lots of
stocks this is an extremely helpful tool function.
Once the scan tool has located and loaded for review a buy or
sell signal you drop the study right on the chart with the click of
the studies button. The program will then highlight the
setup.
The program gives the user a buy or sell signal, then the human
variable enters the equation. There are some signal formations
that are better than others. This is a good setup.
Here is how I would trade this short signal on the QQQ daily
chart above.
The program will highlight some signals that meet the coded
search however when you view the formation it is not a good
formation to trade. If the A-B-C bars are spread out over a
large area or have several very long bars then be cautious trading
the setup.
It pays to review the charts setups to get a feel for what is a
good setup and what is a weak signal. The program does not
know the current trend. If the market is weak look more at the
short signals. Use the EMA (Exponential Moving Average) to
filter trade setups.
EXAMPLE OF A WEAK SIGNAL
If you get a signal that is counter to the current trend use this
as a warning that a trend reversal could be pending. The next
chart is RFMD daily showing the April reversal.
The BUY signal is highlighted on the chart. Notice that you
have three buys setups in a row at or near the bottom. When this
happens it rings the bell that a trend reversal could be near.
The buy setup in the middle of the downtrend never has the price
alert triggered.
Also, that setup should be filtered out from consideration by the
falling EMA.
The BUY setup is colored A-RED, B-BLUE, C- FUCHSIA and two white
confirmation bars. The BUY price alert signal is when prices
trade above the high of the B-BLUE bar.
When a signal is located with the trade going in the direction of
the trend the signals give you great entry points before a
move. Use caution entering a trade counter to the existing
trend even if a setup signal exists. When a setup comes
counter to the current trend wait for the trend reversal to be
confirmed. Confirmation of the reversal would come when the
trading signal price trigger has been hit. If it is a buy
signal during a downtrend, after prices penetrate the price trigger,
then wait for prices to stop making new highs. After prices
have retreated from this last high for three to seven bars enter a
trade only if prices penetrate that last high price bar. When
a setup signal comes in the direction of the trend you can be way
more aggressive with your entry.
The next step is to review the formation of the setup. If the ABC
bars are far apart then avoid trading that formation. If
prices gap and trigger the price alert do not chase the stock.
When the signal is triggered stocks can and will pull back to
Fibonacci support levels before resuming the move. Other times
the stock will hit the alert and be off to the races. Your
skill level and style of trading will determine your entry
techniques using the setups. The back testing program will
allow you to experiment with an infinite combination of entry and
exit criteria to match your trading style.
These trading setups consist of five colored bars being
highlighted on the chart. The description of each bar color is
described in the program instructions. The import bar is the
BLUE bar. The blue bar is the signal bar for both buy and short
signals. In the buy formation the HIGH of the blue bar is the
buy price trigger. In the short formation the LOW of the BLUE bar is
the short entry price trigger. It is most prudent to wait for
prices to close above or below the price triggers. Programming
the effect of the human variables of trade setup interpretation and
trade entry techniques is impossible. Back testing uses the
HIGH of the BLUE bar as the buy entry signal price and the LOW of
the BLUE bar for the short signal trade results detail. Not
every trade that prints in the trade output widow would be entered
in live trading, due to human interpretation of the trading
environment. However, back testing gives a very good idea of
what you can expect to happen.
I like to trade buying options using the daily signals.
When the price alert has been triggered for a short trade I wait
until prices stop making new lows. After prices fail to make a
new low I watch the rally counter to the short signal. After
prices rally for 3 to7 bars I look for a bar to close counter to the
rally trend. Look for this reversal at a Fibonacci support
level. The bar close counter to the rally trend is my signal
to buy put options. You can be more aggressive with your entry
using the alert trigger price. Use Stochastic as a
filter. If the Stochastic is reading overbought and crossing
over then dont take that buy signal. If Stochastic is way
oversold and crossing back over then dont use that sell
signal. There are plenty of great trading opportunities the
scan will find. Be patient and wait for a good formation in the
direction of the trend with confirmation from additional
studies. The short signal is great in any time frame.
Look for a volume spike on the Blue bar when the signal is
formed. This usually indicates a good signal.
I would recommend that you study the charts and become familiar
with the behavior of prices in relation to these setups. Back
testing can give you a clear picture as to how each stock performs
using these setups. When reviewing the back test results look
at any losing trades and make sure an error bar did not trigger
it.
The time factor for watching a setup is controlled by the
user. Back testing results vary according to the time frame
(number of bars) that one looks for prices to trigger the alert.
The default setting is to test the first ten bars after the
trading setup is confirmed. After ten bars, if prices have not
penetrated the signal, then eliminate that setup. The
strongest moves seem to occur if prices penetrate the signal within
three to four bars after the trading setup has been confirmed.
The back testing program allows you to experiment with the number of
bars to review for trade entry.
In certain situations these trading setups will have price alerts
set at prices that other traders are naturally watching including
the Market Makers. The program has a feature that allows you
to offset your alert by an additional amount above or below the
obvious trigger price. Market makers will engineer runs of the
standing orders at these points and then let prices reverse.
Wait for confirmation of the move. No need to rush. If
you miss one there is another setup the click of a button
away.
Back Testing
The back test mode of this program was not created to optimize
results to lure novice traders into buying an expensive
program. As many people are aware the programmer can optimize
lots of back test programs to produce good results. Then when you
try and trade the system it does not work in live trading. I
developed this back test program so that I could find the best way
to increase MY odds of entering a successful trade. It is a
very functional tool not a black box. With that in mind,
remember that no two stocks or groups of stocks behave exactly the
same. Therefore, you must be able to alter your various entry
and exit criteria to find what works best for that stock or group of
stocks. Different time frames require different
criteria. This program allows you the flexibility to test and
develop the criteria that will match your own individual style of
trading. The back test program allows the trader to test many
combinations of variables to find ones that work consistently.
Here are some of the variations you can use either individually or
in any combination in conjunction with the setup signals.
ENTRY PRICE
1) You can use the Trigger Price set by the scan program.
That uses the high or low of the BLUE bar in the formation.
2) You can also use the Trigger Price set by the scan program
but add or subtract an amount to simulate slippage. Or
patience.
3) You can test using the CLOSING price of the bar that
triggered the price alert.
This can be used to make sure that an entry or exit would have
been obtainable. However, it should be noted that lots of time the
bar that breaks the price alert could be a bar, which makes a
large move. Therefore, using the close of that bar can give
a distorted entry price. You do not buy or sell at the close
of a long bar. These trades would be eliminated by the human
factor but not by the back testing. So when using the close
in back testing what could have been a great signal can show up as
a loss in the trade output window. Review the trade results
on the chart.
FILTERING THE TRADE FOR ENTRY
1) You can test the effect of using a Exponential Moving
Average to filter out trades setup signals. The program uses
whatever EMA you have set in the default settings. We all
know how many different EMA timeframes someone can test to find
which works as the best filter.
If the 20 period moving average works for AMCC but the 67
period works for IBM you can see historically which worked the
best. You can use this filter independently or in any
combination with the other filters and entry and exit
criteria.
2) You can test the effects of using a Bollinger Band
filter.
Note: The Stochastic is a great study to use when reviewing a
setup signal. It is not included as a back test filter
because of the programming constraints.
EXITING THE TRADE
1) Exit using a regular dollar STOPLOSS that can be set to any
amount.
2) Exit using a dollar GAINSTOP that can be set to any
amount.
3) After you have entered the trade you can test exiting on the
first bar that closes counter to the trade direction and below the
low of the previous bar. This filter can be used in
conjunction with the STOPLOSS.
When back testing using this exit criteria variable you are
able to adjust this exit variable in such a way as to avoid
inaccurate results that can be caused by a narrow trading range
before a large move. This exit condition and condition 3
have a separate control on them that will void the exit if the
trade would not lose a specific value. This allows you to
have the program test for exit if the bar closes below the low of
the previous bar, but only exit if the trade would cause a loss
greater than (example.50 cents). This helps to eliminate
narrow range bars from causing unnecessary exits.
4) After you have entered a trade you can test exiting after
two bars close counter to the trend, which you are trading.
This exit strategy is also controlled by the dollar control as
described in # 3. These can be used individually or together
in any combination.
Back Test Trade Report Details
The trade output window provides a quick and efficient viewing of
each individual trade
In addition to the normal totals output information. The
individual trade detail allows the trader to quickly view the
following information on each trade.
Entry = trade entry price. Low = the lowest
low price traded after you have entered a long position until the
trade is Exited Pain = the point value reflecting the
difference from your entry price to the lowest low incurred before
the trade was exited. If "none" prints then no prices lower
than the entry price were incurred before exiting the
trade. Exit = The trade exit price. Profit =
The trade profit or loss. EntryDate = Trade entry
date. ExitDate = Trade exit date. These
are examples of the information provided in the back test
output. These are BUY back test results using the signal price
trigger for entry. No filters. StopLoss of 3 points and
a GainStop of 3 points.
Note: Back testing results using the Buy or Short price triggers
while using NO stoploss, produces trade results of 100% on both the
Long and Short side. That is correct, 100%. Not just on
these 3 stocks listed below.
Note: The output is listed in the following order:
Each individual trade detail The number of signals tested
and the number of those traded The Symbol with the normal
totals output window. Number of shares tested = 1 ABC

The program provides you the flexibility to adapt trade
parameters to your own style of trading. Once you are
comfortable with the back test results you can then scan looking for
the setup with the filter parameters you have back tested.
In conclusion, the age-old question has to be asked. If
this trading program works so well then why is it for sale?
The answer is that it is not for sale. I am not a company
marketing Trading systems. I am an individual trader who
developed this for my own trading activities. I do not have
the time to offer a free demo and free support. Individuals
can lease the program on a monthly basis for a fee of $100.00 per
month. Anyone who leases the program will be provided with
support and upgrades. No long-term agreements.
Because everyone trades different stocks in different time frames
there would not be a negative effect by multiple people using the
same program.
