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

DT,

 

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 :-)

 

best regards,

herman.

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...
