Re: [amibroker] Null constant

["CS" <res1wgwl@xxxxxxxxxxx>]

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 
  ?

  Thank you in 
  advance for any piece of help.
