Hello Paul,
Eventually, if you keep going, you will develop your own trading
style. For that reason I try to avoid imposing my
biases on other traders but as a general rule of thumb, simpler is
better.
Later when you are designing systems you will find that a small
number of trading rules in a system has advantages;
it avoids overfitting and returns a higher frequency of signals.
Yoy might be interested in CANSLIM.
If you search the web you will find the homesite for it.
Some of the traders here have an interest in it.
I think some of Don Lindbergs posts discuss explorations etc that
are related to that type of approach.
A couple of comments on your code that might help.
Assigning a variable is generally a pre-cursor to using it in
another formula.
If a piece of code is complicated it helps to understand the process
flow by assigning it to a variable and then in later code you only
have to refer to the variable as a form of short-hand for the
original code.
Also if you are going to use the code in several formulas it saves
having to rewrite it e.g.
M = MA(C,15);
R = IIf(ROC(M,1)> 0,1,0);
Plot(R,"ROCDirection",1,1);
Incidentally, if you copy/save the above and insert it in a chart
pane it will indicate when the chosen MA is going up or down.
In your code example you don't need to assign your statements to a
variable as they are all true or false statements.
The code will simply return true (1) if they are all true and false
(0) if any one of them is false.
As an example copy/save this code and insert it into a chart pane.
Progressively comment out and uncomment each line and you can see
that the plot is always 0 or 1, depending on the truth of your
statements.
Plot(C>0 ,"Test",1,1);
//Plot(C>0 AND C>O,"Test",1,1);
//Plot(C>0 AND C>O AND C > MA(C,15),"Test",1,1);
The true/false output is very useful in more advanced formulas e.g.
when the ROC of an MA changes from 0 to 1 the MA is at a turning
point or pivot point.

seems that Amibroker requires that you give the moving averages a

a comparison.

isn't smart enough to look forward to see that you will define
MAproperOrder in a later statement.

and get your variable defined with a value. You were writing a
logical statement, so it requires the iif statement, I believe. The
iif statements are the same as Excel formula format.

> Hope this helps - it's hard jump starting any new programming
language, but I can assure you that Amibroker is efficient with
their code and it's rational. And it's compact compared to some of
the other systems. I'm working to think like it thinks.... it's
generally more logical than I am... Hard on my brain some days. I'm
a rookie as well as you. Takes a while and what I think will work,
won't necessarily. And it seems that your code should work, but
this probably will. The pro's here can make this stuff work with a
lot of combined expressions, but I stick with one step at a time.
