HI Howard.
I didn't buy the book. However, Torbjörn Ohrt
did and was able to code some AFL from it. His preliminary results on one
stock seemed very promising, which was what perked our interests. Check
out his post from May 28.

Hi Chuck --
I have visited the web site and have seen
the ad for the $97 book, Short Term Swing Trading by David Graeme-Smith.
Here is the link:
http://www.shortswingtrading.com/?hop=netdoc
Does the book describe the system in sufficient detail that the
AmiBroker code can be written?
There is a discussion of the book at
this site:
http://www.trade2win.com/boards/showthread.php?t=10750
One
of the postings is:
-------------------------------
It uses a popular
technical indicator, confirmed by price action, to signal trades (using EOD
charts). When the price is above a widely followed daily moving average only
long trades are taken, and vice versa for short trades. Exits are determined
by trailing stops. Key to the workings of the system is the selection of
tradeables with the right "personality" - i.e. those exhibiting smooth trends.
The package includes watchlists of UK & US stocks which fall into this
category.
Experienced traders, familiar with TA, will gain little or
nothing from this e-book. It would be most useful to those with little or no
experience, as it is commendably easy & simple to understand & follow,
with a reasonable money management strategy, and it`s cheap! So far I`ve only
backtested it visually on past charts, but it appears to be a sound method for
EOD swing trading.
------------------------------
Does your reading
of the book agree with the poster?
If that is true, then AmiBroker code
that is already available in the AmiBroker Library and among the AmiBroker
User Functions would be sufficient to create a similar system, and mentioning
which of those are good candidates for further exploration would not be a
violation of copyright.
Thanks,
Howard

The problem is that the source of the code is a $97 book. I'm no
lawyer, but I don't see why sharing ideas (in your own words), or even code
that you have written, for free, based on a book that you purchased would be
be protected in any way. But then I also know that copyright laws are
changing every day.

Greetings all --
The results that have been
posted will generate a lot of interest. Certainly the backtest
results do not violate any copyright. But the etiquette of these
lists considers backtest results without code, or at least a detailed
description of the technique, as spam.
Would someone please
post a link to the document that is being used as the source for the
code? Those interested can obtain their own copy, join the
appropriate discussion groups, and be free from any copyright
restrictions.
Thanks,
Howard

Dave,
I don´t think copyright is violated by sharing backtest
results with
AB users? I have no intention to reveal any of my
coding without
permission from the author of the system. I won´t
even discuss the
nature of the system at all, sorry. But as you open
my eyes to
potential legal problems I will contact the author before
sharing
more results. Perhaps it´s better to follow your
advise.
My involvement in this discussion originated from the
suggestion from
Dr Alex Chambers, on this forum to visit the SST
site. He suggested a
monthly return from the system, which exceeded
my horizon. My
backtesting so far is incomplete, as I have not used
the position
sizing suggested by the author, having still to read up
on how this
is coded in AFL.
Ton, you have to wait a bit for
the results...
T.O.
