I compared your "Weekly MACD - Close" with the built-in Metastock
MACD. As you said, it's an excellent match.
I have a question on your formula. In some cases, you repeat the
definition of a variable. For example:
I:=Fml("Calendar Week counter");
I:=Abs(I-ValueWhen(2-G,1,I)); M:=G OR I>0;
Is this similar to usage in computer programming? For example,
x:=x+1. Here, the old value of "x" is being operated on to produce a
new value.
Here are my first attempts to decipher your "Weekly MACD - Close":
total confusion and disarray.
G:=LastValue(Highest(Sum(DayOfWeek()=F,5))=5);
Split into smaller pieces:
a:=Sum(DayOfWeek()=F,5);
b:=Highest(a);
c:=LastValue(b=5)
Explanation:
a:=Sum(DayOfWeek()=F,5);
--------------------------------------
The value of F is input by the user. Assume F=5, so no trading on
Saturday or Sunday.
Assume that today is Monday (=1).
Therefore:
Today: [DayOfWeek()=5] is False, or 0
Previous day, Friday (because F=5): [] is True, or 1
Thursday: [] is False, or 0
and so on.
Therefore,
a:= the sum for five periods, (0,1,0,0,0), which is 1
It seems to me that the sum will always be "1", so already I must be
losing the thread :-)
If I plot this bit as an indicator, I get a horizontal line at Y=5
going back to 1994. This implies that the daily values are all "1"
:-)
--------------------------------------
b:=Highest(a);
--------------------------------------
b is the highest ever value for "a", starting from the first day
loaded in the chart until today.
By my analysis (paralysis?), this can only ever be "1". When plotted
in Metastock, it's "5".
--------------------------------------
c:=LastValue(b=5)
--------------------------------------
If the last value of the data array "b" is equal to "5", then c:=1
(True).
Otherwise, c:=0 (False)
A few hints would be appreciated.

Alan
