Thanks DC, for your nice post; I am sure many will identify with your
current position and, as well, many will remember the days that they were in
your position. So you are never alone, no matter at what stage of afl use
your are: you have always lots of company.
I am not that young either: retired, white hair, the whole bit :-))) and
yes; in some ways we may be past our prime but in other ways we may be able
to teach those yound object-oriented-wizards something, some of the time ;-)
I stumble along like many others but I'll get there eventually. I don't
worry about being wrong or look like a fool, you progress a lot faster if
you dare to ask stupid questions.
The best thing is to zero in on what you need and focus on a goal, don't try
to cover everything. Pick one or another trading idea that appeals to you
and try to develop code for it. After having completed one simple system a
lot of things will become clear.
Good luck and feel free to post you questions if you need help,
herman.

Hi Herman,
Thanks for the input here, as well as in your other posts. I hope to get
to the point where I can make use of ALL the features AB offers. But I'm
handicapped in my attempts to learn AFL by my lack of understanding of the
terminology used to describe what the various functions are meant to
accomplish, and by my inability to visualize what a given combination of
functions will produce.
For instance, I've seen some references to "scalar" versus "array" values
being returned by a function; pardon my ignorance, but without looking it
up, I'm not certain what "scalar" means in this context. To me, a number is
a number - how would AFL know if it was a scalar value or an array value? I
assumed ALL returned values in an array-based language like AFL would be
array values. So I lack some fundamental knowledge that would make learning
AFL easier.
The only language I ever used previously is BASIC (never any Easy
Language-like programming, as in TradeStation). The BASIC program has helped
me in some cases, but has confused me in others. As another example of my
terminology-challenged mindset, I have never understood the term
"object-oriented", or why it has any significance. When my son tried to
explain it to me, I must have looked like a dog trying to understand a new
command. Remember, I only know how to program in BASIC, so my programming
growth was stunted (according to my son). To my way of thinking, EVERYTHING
is an OBJECT. What's so significant? Why would it matter?
Regarding my visualization limitations, my son can play a game of chess
without ever looking at the board. I, on the other hand, honestly can't even
visualize an empty board, let alone the positions of the pieces of both
sides. So even though I can understand simple functions like "HHV", I can't
fathom most of the others, even after reading the descriptions. I have to
see a simple line of code with only one or two functions, and then view the
output to be able to internalize the concept. Then I can move on to the next
function. Then I can figure out how to combine them in more complex coding.
This takes a lot of time, and the older I get, the less time I seem to have
in a day (I'm sure I'm not alone there!). It's a frustratingly slow way to
learn, but I don't know how else to do it. When I look at some of the one-
or two-page formulas with three or four functions embedded in one line, my
jaw literally drops; I don't have the slightest notion of what's being done
in any given line of code.
One function at a time... one function at a time. You should have seen me
struggling with "IIF". I kept trying to use it as an IF, THEN type of
command, as in BASIC. OK, OK, so I'm obtuse.
I'm sure the new "Drag-and-Drop" code building feature is undoubtedly a
great tool for most users; but without some concept of what 90% of the
functions are meant to achieve, it's not a tool I'm yet able to use.
Alright, I'm done whining about my personal deficiencies... But if someone
could write that "AFL For Dummies" book, it would be helpful... : )
Best regards,
DC

[DC] Probably the only way to make the AFL approach better would be to
have
AmiBroker write the code itself, based on verbal command in your natural
language.
Perhaps you should have another look at the new Drag&Drop features...
you
can now cascade code modules and "build" indicators and systems without
seeing/editting afl code. Ofcourse you have to understand what you D&D
and
probably you want to create some of your own custom indicators/modules
and
add them to your Chart's workspace. You can create System Building
blocks
that, when dropped on several indicators, will give you buy and sell
signals. No other software i have seen has this capability. Development
work
can be reduced since you no longer have to edit code to test various
parice
arrays and signal arrays, just select them in the param() window,
I haven't seen anybody exploit this, but the capability is there NOW.
best regards,
herman

I hve used Metastock (too limited), TradeStation (too pricey), Dynamic
Trader (somewhat pricey, but gorgeous charts), Fibonnaci Trader (no
longer
unique), Ensign, Sierra Charts and QCharts (ho hum), and Neo Ticker (not
as
user friendly or intuitive IMO), and one or two others whose names I
can't
recall.
Amibroker can do anything the programs above can do, barring some
proprietary indicators (but if you can figure out the code, you can
program
AmiBroker to do it). The only other thing that AB can't do is plot
indicators beyond the rightmost bar on the chart (e.g., displaced moving
averages), but I think a few of us have suggested it be considered in
some
future update. PLEASE, PLEASE, PLEASE!!!
Every update Tomasz releases contains something of practical value. If
a
given release contains bugs, they get handled quickly (or so I gather
from
the comments I read).
I'm still struggling to learn the AFL, but there are usually enough
formulas already posted so that understanding it is not TOO awfully
difficult. I could still use an "AFL For Dummies" reference, because I
tend
to make it harder than it has to be. Probably the only way to make the
AFL
approach better would be to have AmiBroker write the code itself, based
on
verbal command in your natural language.
I guess the bottom line is this: if you've been looking for a program
that
can do almost everything NOW, and perhaps will in the future, and has
support that is EXCELLENT, then AmiBroker is the end of your search.
Just in case yopu wonder, I have no affiliation with AmiBroker or its
staff, apart from being a very happy owner.
DC

Would like to hear your opinions. If you have had a chance to use
other similare software (wealth-lab, tradestation, metastock...) how
does amibroker compare against them? It obviously beats them when
it
comes to price but are you satisfied? Pros and Cons, limitations,
bottom line?
I just installed trial version and have intraday strategies that I
would like to try out. Not sure yet if Amibroker can do the job.
Thanks for all your answers.
