Bill,
OK, I took your advise.
I have strong motivation to improve AmiBroker and
include good ideas coming in from various sides.
I just need to co-ordinate the suggestions into
something useful.
I appreciate your suggestions and will certainly
use your ideas and feedback
in the process of designing and developing next
versions.
Thank you.

The option as to where AmiBroker goes and howuseful
it is resides in your hands. There is nothing that any of the userscan
do about that. AmiBroker is not complete and either is Wealth-Lab.
AmiBroker has the ability to easily be everything Wealth-Lab and Ensign are
and much more. Lots of good ideas in AmiBroker, but a need for some
basic things in currently weak areas.

One more thought:
I just wonder what would you like me to
do? Duplicate Wealth-Lab? What for?
If Wealth Lab is perfect tool for you- just
use it.

You are missing the point. The DrawLine
function does not exist because Wealth-Lab does not have manual drawing
(but I would be surprised if that does not appear soon).
Instead, with DrawLine and similar functions
Gann, Fibonacci, and other line-type studies can be effected
after calculating where the two points are. The object then is
to draw the lines between those two points. You will never be able
to do such studies with a trendline tool with or without the Study
function. For example, can you draw a Gann fan or Square of 9 with
the trendline tool with anything approaching the required precision and
accuracy? Or, there are Fibonacci retracement levels and techniques
that are not part of AmiBroker's canned indicators. Can you draw
those with a trendline? Could you draw the Fibonacci retracements
that are in AmiBroker by hand? For trading purposes, not in a
zillion years. If you are not familiar with these studies,I
can suggest some references and provide some gif examples. By
the way, along the same lines there are similar functions such as
DrawCircle for Fibonacci arcs, etc. Bottom line is that such
functions are very valuable to users, reflecting their power and easeof
use.
Hope this helps.
Bill

Bill,
I guess DrawLine in Wealth Lab exists simply because there is NO
way to simply DRAW the trend
line by hand in WealthLab.
Speaking about easy of use:The line between two points can
be simply drawn in AmiBroker. Take a trend line tool and
draw.
No need for code. I guess this is much easier than writing the
code for drawing a line!
Then you can use the lines drawn using study() AFL function
as shown in the newsletter

Tomasz:
FWIW, from a users viewpoint, there is an
advantage to functions that combine other functions into a single
entity. Easy is good.
As for DrawLine, you have picked on one of
my favorites. I am not aware that any combination of graphXY
functions can draw a line between two user-defined points, at
least not as easily as far as I can tell. You have coded a
number of indicators (e.g., ADX, etc.) that one can graph with
graphN. If I am smart enough, I guess that I could go the script
route and develop new functions that could then be used with
graphX. I am not an expert programmer so to do so would be nice
but would have to be a labor of love. Being able to draw a line,
including extending it into the future, between user-defined
points would be a big deal that opens up the opportunity for a variety
of line studies. Combining such a function with an Input
function (especially if inputs can be done by pointing and clicking)
opens a universe of line-type studies (e.g., Gann and Fibonacci) to be
programmed, which is a big deal to some of us. Not to be
overlooked is the fact that DrawLine gets programming dummies
like myself into business literally within minutes. Sure,
experts like yourself are up a running in the same amount of timewith
AFL, JScript, VBScript, etc., but as evidenced by the discussion
on this board there are many in the "dummy" camp. "Talking
down" is not always bad.
Just my two cents.
Bill

Backtesting reports
Hello Bill,
What I wrote was my personal opinion,
nothing more.
I had a chance to hear the opinions
about AmiBroker from different people
and what I learned is that there is a
very wide spectrum of different views
and preferences among T/A people.
AmiBroker is not all about backtesting
(while WL seems to be). AmiBroker
tries to satisfy these needs
as much as possible. Unfortunatelly
different needs are sometimes contrary
to each other.
This applies especially to the
programing language.
One may say he would prefer asimpler
language another one likes sophisticated
and very complicated tool. I like to
code in C++ others like Basic, Pascal and do on.
I have my reasons, you can have
yours.
That's why I am providing in fact 3
alternatives: you may code your formula in
"pure" AFL, you can use JScript or you
can use VBScript. You can also mix
the languages in a single
formula.
The AFL itself will be improved
further so you will be amazed someday :-)
To the details:
1. <FONT face=Tahoma
size=2>Yes, BuyAtStop andall trade
control functions are nice, because
it is clearer to say BuyAtStop
than doing buyprice, buy stuff together the right
way.
2. GetDate, CumUp - I don't see WL
advantage here
<FONT face=Tahoma
size=2>
3. I
don't find any advantage of DrawLine and SetBar color since
completely the same
could be done in AFL using graphX,
graphXstyle, graphXbarcolor. All the difference
is that in WL you call a function
while in AFL you assign a variable. I can add a
function
that is called DrawLine and will
internally assign the variables so there is no real
difference,
... maybe except AFL can drawtrue
Gann Swing charts (see AFL library)
while WL doesn't have square line
style chart.
A bottom line:
Trade control in WL is betterand
nicer and I am willing to improve this functionality in
AFL,
I like also the statistics inWL. I
think that there are lots of nice ideas in WL to get an inspiration
from.
And I really appreciate that you
pointed out the things you like in
WL - I learned something again.
All I dislike is a modal,
Borland-looking (ugly icons on every button), bold-font everywhere
user-interface.
This is however my personal opinion
based on my personal taste.

Tomasz:
Have to disagree to some extent.
As you note, the interface is a matter of personal preference,
although I tend to side with Bernard. However, and most
importantly, from a "programming dummy" user's viewpoint,
WealthScript might suffer from the problems that you note, but it
is relatively clear with respect to trading system and
drawing functions. Perhaps it is not as efficient as AFL,
but it is easy to build a system with commands like BuyAtStop,
GetDate, CumUp, etc., with only a couple of tutorials asa
guideline. And being able to incorporate drawing functions
(e.g., DrawLine, SetBarColor, etc.) in a straightforward manner is
great, although more is needed in this area (to be expanded in
version 2 according to WL). Definitely an attempt to
produce a user-friendly programming environment. Easy to
use, "intuitive" system and drawing functions are arguably
essential endpoints. So much the better, if these
attributes can be further enhanced with respect to speed and
simplicity, and placed within the AmiBroker setting. Orso
it seems to this programming dummy.

Dear Bernard,
Thank you for your
opinion.
I have downloaded a trialversion
of WealthLab desktop and had a look at it.
Frankly speaking I don't like its
user interface - but this is my private opinion.
What I like are extensive
back-testing statistics. These I would like to see
in AmiBroker.
As for the WealthScript Ifind it
quite complicated. You have to have at
least
3-4 times more code than in AFL to
do the same thing.
Also - I tried to check very
basic MA crossover system and wanted to simulate
trading using 100% capital and
WealthLab displayed very strange equity curve
(with negative cash amounts).
What's more WealthScript seems to be very slow.
As for optimization: yes I will
include optimization in 3.7, this will include
multiple-security
optimization.
By the way: it seems thatyou can
only optimize for one stock in WealthLab, is it
true?
Anyway, some ideas are worth
implementing.

[amibroker] Backtesting reports
Dear Tomasz
I have a doubt if my
message was published since I can't see it and in fact I
haven't finished it. So here it is completed.
Well I like the following feature
(in the desktop version):
-A window where you can easily
find the systems/commentary classified in folders and sorted
by name or date etc.
-The ChartScript window,the
equivalent of the AB main window, have some TAB where youcan
very easily evaluate a TS : The first one show the
performance, the second the list of the trades, then one for
the alerts, one for the text of the TS, one for optimisation
(I hope that you will implement it in AB soon), an other one
called MonteCarlo (I guess it is to make more complex
optimisation using the Monte Carlo method), the last one is
called Analysis Var but I don't know what it is.
They have also a window where you
can select the trading systems, run them on a watchlist
and perform a ranking of the performances..
You can download the desktop
version for a free trial period and have a good idea of the
product.
It is much more expensive than AB
but you have given to us the proof that you can easily compete
with such products.
In fact more I try to find a good
trading systerm more I came to the conclusion that there is
not one good trading system but we have to find for
each period of time, for each market and perhaps for each
stock one good TS which could have to be changed and adapted
as soon as the market conditions move.
This means that we need to have a
tool that allow us to optimize and compare a bunch of TS
periodically.
So I whish that AB couldhelp us
in this task and allow to adapt and optimise our TS
easily.
For this Tomasz it wouldbe nice
if we could more easily change the parameters of the TS or the
charts with contextual menus intead of having to write AFL
codes.

Hello,
Thank you forthe
information.
BTW, here is a
definition of Max. Intraday drawdown from
wealthlab:
"Max IntraDay Drawdown
This value represents the greatest
peak to trough distance in your equity curve.
Beware of Systems that have a high Drawdown
value."
This is exactly what I meant in my
previous e-mail: "greatest peak to trough
distance".
Now: how should we call entryto
lowest trough distance ( a drawdown measure already
present in AmiBroker) ??

Since you will have
maximum drawdown, I suggest including
Risk-Adjusted Return (RAR). This is a
standard system evaluation metric that divides a
risk measurement by the annualized rate of
return. You could use maximum drawdown as
the risk measurement, but other measures
(volatility, standard deviation, etc.) would also
work.

version 3.64 already included are:-
Annual system percentage profit- Annual
B&H percentage profit- Maximum

value to the minimum equity value
(BTW: How to name this one? I have no
idea) (note this is different from
