Jerome,
I see your point.
Since [i] is an array counter and not a bar counter, the array
for MA(C,5) is valid from Array[0] but not from Bar[0].
Someone has a solution, unfortunately I don't.

I
know actually the IsNull() etc ... functions, but I need also a mean to test a
null value in a for loops. The code was just given as a simple
example.

Re: [amibroker] Null constant
Jerome,
You don't need to go through the complexity
of a FOR loop.
test=<FONT
color=#ff0000>IIf(<FONT
size=2>IsNull(mo),1<FONT
size=2>,0<FONT
size=2>);
Plot<FONT
color=#ff0000>(test,"Null=1"<FONT
size=2>,colorblue,1<FONT
size=2>);
There are several functions for testing presence
of valid data:
IsNull
IsEmpty
IsFinite
Nz
IsNaN
IsTrue...

Subject: [amibroker] Null
constant
<FONT face=Arial
size=2>Hello,
<FONT face=Arial
size=2>
Until yet, I
have not succeeded in using the "Null" constant in for loops. In the
simple following code, I would have expected the first 5 bars of the
"test" array to hold a "1" value. This is not the case, so the expression
(mo[i] == Null) does not return a true result even when the MA(C,5)
doesn't return any value. Is this by design or do I use this constant in a
wrong way ?
<FONT face=Arial

Thank you in
advance for any piece of help.
