Hello
ken,
basically I process the OHLC arrays a number of times, at each stage i
end up with new a number of OHLC arrays. Right now I have one long program that
is difficult to manage, i know i could use Include files but they are a bit
awkward to maintain - i am forever changing my code.
With
the new D&D capability i decided to partitioning my code into modules
that each produce plotable arrays - i find this nice for
debugging. I use the ParamToggle() to turn on/off plot functions in
each module. Before I had to keep track of many variable names and make sure
there were no conflicts within the long code. The D&D operation isolates
(keeps local) the variables within on Section, so now i can use variable
names without worrying that they are used somewhere else.
Let us
say my last Dropped Indicator had three arrays that I want to pass to the module
that will be dropped on it next (implement the next stage of my price
processing), I would plot the three arrays (visibility Param controlled) so that
i can use the in my next Indicator using these statements:
Array1
= paramField("Array1");
Array2
= ParamField"Array2");
Array3
= paramField("Array3");
Each
one of these lines will result in a drop down menu in my Param window where i
can choose the array to use, I like this, again for debugging as i can also test
the code with normal OHLC arrays. This way i can "feed" my dropped section
any kind of data i like. the whole project becomes more manageable - at least i
think so.
I only
started this today so we will have to wait and see how it will work out... I
lost my internet connection today so the day wasn't very productive
:-(
best
regards,
herman.
Hi
Herman: I am still learning and playing with D&D and so, I do not really
yet have an appreciation for HOW one does what you have said below in
red. Can you say a few more words and/or offer me and others a
simplified example of what you are talking about.
Thanks.
Ken

the D&D procedure
promises to simplify my code significantly. I
can use many ParamFields() to pass any number of arrays from (D&D) module
to module.
I think D&D
greatly helps "connect" and simplify cascading code segments. It will reduce
naming complexities as we can develop code in modular form, i now pass arrays
from one module to another with an invisible plot. In fact i am breaking up
lengthy code into smaller modules which i can D&D to create my earlier
complex single-code indicator - i am finding new opportunities because it is
so easy to cascade indicators: new relationships
are emerging.
I also find the
D&D a time saver as it lets me "play" with functions and indicators in a
small fraction of the time it took me to do the same in code. The new
procedure is experiencing some growing pains :-) and some users may have
to learn some new concepts, but this is what gives the AmiBroker
user "the technical edge" needed to do better than others. It will help
us develop new trading methodologies - soon we'll have a very smooth code
building machine.
Yes, users will have
to have a basic appreciation of what they are doing in afl, but so is that the
case with trade delays, loops, and a myriad of other techniques. There is a
learning curve, but this is not any different as compared with any other TA
platform, except that this one has a future :-)

Thomas,
d&d is a big help but it is not magic, we should know
some AFL basics
to make it
work.
RSI() is applied to Close,
you need RSIa() to get the RSI of an MACD
for example.
Zig() should be applied to positive arrays only a Zig
over an MACD
would work via
d&d BUT the result will be wrong [since MACD is
negative from time to
time]
IMHO this is the only
negative impact of the d&d, users should not
use it like a toy, a good AFL knowledge is required to
make things
easier.
On
the other side, when we d&d 2 or 3 indicators in the same pane,
take a look at the IB code : It
is perfect, it is VERY WELL written
but it is not written by the user !!After the great
result of the
magic "Apply"
button, the user should study carefully the new code
and understand its structure. I
do not thing it is easy, especially
because the magic result is already available in the new
pane.
Just some thoughts on the
new d&d feature, nothing more...
Dimitris
