uses for the #Include
I
don't use Include extensively at this point.
<FONT color=#0000ff face=Arial
size=2>
But if
id were to do what you are suggesting then I'd probably devise a naming scheme
along the lines of:
<FONT color=#0000ff face=Arial
size=2>
Use
the name of the indicator or some sort of mnemonic as part of the variable
name:
<FONT color=#0000ff
face=Arial size=2>IE. mac10 = Ma(c,10);
<FONT color=#0000ff face=Arial
size=2>
its
best to be consistent throughout you system. For instance use the same scheme in
naming your indicatiors, file names, variable names. Keep them unique of
course. Using X, A, etc doesn't do anything but save space and can lead to
confusion when the formula is cold. I try to be verbose (within reason)
with the variable names so that it can help me to remember. the challenge
can come when you have a lot of different variations on a theme. But
you can get creative there too with version numbers (if you're really anal you
can keep a list of variable names, version numbers and a description
of what they are/do - and if you're creating a lot of these then you better do
something like this or you'll have a mess and will wind up re-creating things
you already have).

<SPAN
class=045393014-27042003>Dale,
Am I
correct in assuming that any of the variable names are also brought in as
well?. example....
<SPAN
class=045393014-27042003>
<SPAN
class=045393014-27042003>indicator A
<SPAN
class=045393014-27042003>x=Ma(c,10);
plus
a whole bunch of other stuff.......
<SPAN
class=045393014-27042003>
<SPAN
class=045393014-27042003>indicator B
<SPAN
class=045393014-27042003>
<SPAN
class=045393014-27042003>x=roc(c,1)+dema(roc(c,10).5);
plus
a whole lot of other stuff..........
<SPAN
class=045393014-27042003>
My
new indicator...
<SPAN
class=045393014-27042003>
a
Whole lot of stuff +
<SPAN
class=045393014-27042003>#include indicator A.afl
<SPAN
class=045393014-27042003>#include indicator B.afl
<SPAN
class=045393014-27042003>
In
this crude example X is a named variable in both indicator A and B. Therefore
if I have used X as a variable in my new indicator I could get results other
than I have planned.
<SPAN
class=045393014-27042003>
I
guess the challenge for me is that I have so little creativity in my naming of
variables. When I use #include I need to first cross check all the code to be
sure that I have not used any variables with generic names (x=,y=
var1=var2=). It would be great if #include simply drew the final
calculation from the called Afl but that is not my understanding of how it
works. You have far more programming background than I, how do you go about
naming all your variables to avoid issues like this?

WHen
you use the include you never get to see the code in the AA window. Amibroker
reads it internally when it runs your formula. This is how you can save
space in the AA window. The code that is "included" should have been
thoroughly tested and error free.

Thank you for that...That much I do know...but how do I read this
file....example..How would I read this in The AA window on an
explore.....Or in theIndicator Builder... TIA Anthony

the #Include You create a directory in your AmiBroker directory that
is called "IncludeFiles", you copy all your include files to that
directory. Then to read the include file code into your system you
insert this line: #include "C:\Program
Files\AmiBroker\IncludeFiles\movingaverage.afl"; h

pre-proccessor yet...mainly I do not know how.... Say I
have a file called Movingaverage....( movingaverage=ma(c,28) ).....Now
I want to use this in some other formula....so I write the following:
#include "C:\Program Files\AmiBroker\AFL\movingaverage.afl"
Now What do I do ?? Thank you Anthony

Hello, The #include does not enhance processing power or
provide additional functions. I substitute it with the full code after
development or for performance testing. However it is extremely handy
for: 1) Making code more readable during development by
hiding a major part that doesn't require any more work. Working on a
program of a few hundred lines and scrolling back and forth, from begin
to end, doesn't make for pleasant working. Breaking it up into modules
will speed up you work. 2) During development, when working
with loops, you can hide the entire body of the loop so that you can see
the begin and the end of the loop and work on the code in those areas.
For quick temporary hiding of code sections use a standard name like
Mod1, Mod2, etc. 3) I plot equity and other indicators from
the backtester using the Equity button, i find this easier than working
from two formula windows. Most indicators contain completed code so they
can very conveniently be put into an #Include file, so as not to clutter
up the systems code. Fred's equity code is a nice example that you might
want to have in an Include file. 4) Some of my systems use
many calibration constants, a long line of 100 short statements messes
up the code and makes it harder to work with. Placing the assignments in
an include file hides them nicely and makes it very easy to switch
constants by commenting out one or another include 5) During
development I use ,any AddCollumn statements, 10, 20, even more. In a
major project it is well worth to develop such debugging tools and leave
them in the code. Simply uncomment them when you need
them... 6) Include files can be used to "attach" documentation
to a program without cluttering the window and using up a lot of space.
Sometimes it is handy to use the Indicator formula window (if not used)
to keep notes in an Include file. 7) Scripts, if used, are
pretty well stand-alone pieces of code and it is nice to hide them from
view. 8) If you use pattern recognition and work with long
lists of patterns or Candle stick patterns, you can define those in an
include file. 9) If you want to translate Status("StockNum")
to a literal string ("MSFT") and you work the N100, you'll need a 100
statements that mess up your code. Also since this type of code can be
called from many other programs it is nice to have it self
contained. 10) You can pass parameters to Include files (as
needed in 9 above) by reserving a suitable variable name for Include
files ,or as I do, i give the include file a long name that tells me
what it expects and what it returns. For example:
N100Number-n-ToTicker-T.afl this files expects a pointer named "n" to be
defined before using the #Include and returns the Ticker name-string in
"T". I define n before the include and use the string T after it.
Easy? 11) I know: I can't count! Some standard Param()
applications that are needed for debugging but not in the final version
- an Include may be useful
here.
