How
do you know if your's or anyone's Trading Strategy will produce a
profit?
|
This is a question everyone of us should ask
ourselves before
we ever put real money on the line. I know because I've been there many
times. I personally believe one should never trade or
invest without a trading strategy. Preferably, one that you know has a
high probability of making a profit when traded properly.
I don't believe that just looking at a chart and thinking this
should go up or down is a good enough reason to enter a trade. For
those of you that have taken my seminar or purchased the seminar CD,
you
know I preach that one should know their expected entry price, their worst-case
stop loss and multiple profit target prices prior to
entering any trade. This holds true whether you are a
daytrader, swing trader, or a long term investor. This is also true
whether you trade
stocks, options, Forex or whatever.
Why is it that folks will plunk down thousands of dollar on a trade
without having the slightest idea of what is going to happen in that
trade? None of us are perfect. We will all experience losing trades,
but isn't it much better to know your risk before entering.
How do we limit our risk and maximize our profit? We take the time
to learn how to do it the right way.
- We educate ourselves,
- We have a trading plan,
- We have trading strategies
- We have trading rules
Finally, we follow our trading plan, we execute our trading strategies
and we stick to our trading rules.
Every time we fail to do these things we increase our chances of
suffering a big loss. Without them, we're almost
guaranteed to fail. |
| But
that's
still not enough |
You have got
to know the likelihood of your trading strategy to make a
profit when traded properly. How do we determine a trading
strategy's profitability? Simply put, we need to backtest the
Trading Strategy. To do that, you need a history of trades
which can be done by:
- "Live Trade" the trading strategy for a
year or more. There is an excellent chance you will have a
lot less money left after doing this method.
- You can "Paper Trade" the trading
strategy for a year or more. At least you won't have lost any real
money.
- You can "Backtest" the trading strategy
over a several year period under many different market conditions.
However, backtesting takes a lot of time, effort and has a
learning curve. Backtesting can be done several ways:
- You can manually backtest as
I did recently with the Trading Strategy Using High Yield Dividend
stocks. That took almost 3 months and hundreds of long hours manually
recording every trade. Using this method means you have to double,
triple, and quadruple check your work because anytime you do something
manually it is subject to human errors. However, some times it is the
only way you can backtest a trading strategy.
- You can use backtesting software to
automate the process and save a great deal of time. Not only
is this faster but it is also more accurate. But there is a learning
curve with the software. I use TC-Companion because it works with
Worden Brothers Telechart software. In my opinion, TC-Companion
is the best backtesting and reporting software on the market and I have
tried many of them. Its only drawback is that it only works with Worden
Brothers Telechart. Hopefully, over the next few years we can
change that and have multiple data feeds, including Forex.
The drawback using software is that your
setup, entry and exit rules have to be well defined
and able to be formalized to where the software can understand
them.
- You can use a combination of manual
testing and software testing when either your setup, entry, or exit
rules require user interpretation.
- You can use a combination of any or all
of the above to create the trade history.
Unfortunately, too many traders/ investors choose the "Live Trade"
option which is the most costly and demoralizing. I know because that
is how I use to trade. The only person who made any real money was my
brokers.
Some
folks will say backtesting does not prove a Trading Strategy will be
profitable. That is true but it certainly goes a long ways toward
helping you be successful. If you are not disciplined, consistent and
have not obtained the knowledge of how to trade then you have
a
high probability of failing. I cannot stress enough that you
need
to learn before you trade or invest.
In 2000, I lost an
embarrassing amount of my portfolio, first by not
learning to trade properly, then not applying what I learned and
finally
trusting others to invest and manage my money. That is when I
decided enough is enough. I, then,
spent a great deal more money to learn the right way. I firmly believe,
people should not have to spend thousands of dollars to learn
to
trade. That is why, I have priced my Seminar CD at a very reasonable
price.
Unfortunately, I
found out that just because training was expensive did not
mean it was good.
The more I learned the more I realized that no one's methods fit me
exactly. I learned to create, test and analyze my own trading
strategies. I encourage all of you to do the same. That is the goal of
my Seminar CD.
I warn you it is not like a quick trip to the corner market. It is a
long journey and one where you will make many mistakes. Hopefully, you
will analyze every mistake and learn from them. Otherwise, you will
keep making the same mistakes over and over. Albert Einstein, was
credited with the saying "Insanity is doing the same thing over and
over
and expecting different results".
Expecting
is the keyword here. In
fact, that brings us to the reason for this newsletter.
How do we know what to "expect"
from our trading strategies?
|
Many
smart people have worked
on this question
for a long time. A few even came up with formulas to help us figure it
out. Two of the most popular methods are Expectancy and Kelly
Criteria ( some times call Kelly Criterion ).
I have created a spreadsheet to automate the calculation of
both. Of course, they both require the trading history of a trading
strategy. The example I use is the "Trading
Strategy Using High Yield
Dividend Stocks" where we analyze all 132 Trades.
In the Newsletter- 01-22-11 I
showed this Trading Strategy had a winning trade percentage of
85%. That still does not
tell us what we can expect from this trading strategy. It is possible,
though highly unlikely, that we could lose money even with this high of
a winning percentage.
Before I go any further, I will tell you I am not fond of the Kelly
Criteria on extremely high winning percentage trading strategies
because most of the time it has you putting too much of your portfolio
into a single trade. That is particularly true in our Trading Strategy
as the Kelly criteria recommends putting 85.6% of our portfolio into
one trade. Please do not do that.
While Dr Van Tharp's Expectancy does not tell you
what you should put into a trade., It tells you what you can
"expect" on average for each dollar you RISK. Notice, I said what you
RISK not what you invested. You need to follow the
process I laid out on the Seminar CD for controlling your risk.
The
Expectancy shows us we can expect to make $3.03 for each dollar we
RISK
While the Kelly Criteria shows an expectation of $3.20 for
each dollar you RISK

Quite a bit of effort went into
learning and developing the Excel
Spreadsheet. Therefore I am not going to give it away for free. I have
placed a very reasonable price of just $9.95 to purchase this very
useful spreadsheet.
Trading
Strategy Expected Performance Excel worksheet is
only $9.95

After
you order the spreadsheet you will
receive it as an attachment in an email confirming your purchase
|
|
I
am not
going to go into details on the calculation of Expectancy or
the Kelly Criteria. The spreadsheet has links to information on both of
them.
The Expected Performance spreadsheet contains
4 worksheets. The one shown below is the
Performance worksheet which calculates all the results based on the
data in the Repository worksheet. You will need to copy/paste your
trading data to the Repository worksheet.
I
have not password protected any of the excel worksheet or cells. Please
be careful as all of the formulas are exposed. I left it this way for
those that might wish to copy the Performance and
Repository into
their trading journal. That is, if it happens to be an excel
spreadsheet. I suggest you make a backup copy if you are going to
change anything in the spreadsheet.
If you decide to
move the performance and repository worksheets to your own
spreadsheet, you will have to change the links in the
Performance
worksheet to wherever you have the trade information.
The
other 2 worksheets contain introductory information on
Expectancy
and Kelly Criteria with links to web pages where you can get detail
information. The Internet is full of people's explanations of
both methods.

| Expectancy = (PW * AW) – (PL * AL) |
|
PW = probability of a winning trade |
|
PL = probability of a losing trade |
|
AW = average win |
|
AL = average loss |
| To convert this formula into
“expectancy per dollar risked” you will need to assume the AL is 1
dollar and the formula becomes:
Expectancy
= (PW * AW/AL) – (PL * 1) |

| Past
Performance is Our Key to the Future |
|
As
I have
stated several times in the past newsletters, I
truly believe that past performance is the best indicator of how a
given stock or a Trade Strategy will perform in the future. That goes
for the overall
market as well. However, it is certainly no
guarantee as there are many things that affect stock prices.
Most of
them
have to do directly with the individual stock and how its company is
performing. There are many factors that affect a sector or the entire
market. That is why even savvy investors have to stay on top of their
position.
As always, know your Risk
before you get into a trade. Know
your Entry, your worst-case Stop-loss and your profit targets. Have a
plan to take some profits along the way. NEVER let a
profitable trade turn into a losing one.

Trading
Strategy Using High Yield Dividend Stocks can be purchased for $49.95
After
you order the
Trading Strategy you will receive an email confirming your
purchase. The email has a link to a zipped file that you will
download onto your hard drive.

This table
shows the final performance results of the Trading
Strategy Using High Yield Dividend stocks. I have to admit that I never
expected while developing the Trading Strategy that it would
have an 85%
win rate. I was also surprised at the
Winner
to
Loser ratio of 4.4 to 1 times.
|
|
At these Win/Loss
ratios you only need to be right 19% of the time
to break even
