<FONT face=Arial color=#0000ff
size=2>Lou,
I
think you have made it more difficult than need be. First take a look at the
syntax for foreign() , do you want AB to fix the "holes" or leave them be?? You
may want to leave the default fixup...
<FONT face=Arial color=#0000ff
size=2>
Cc = <FONT
size=1>Foreign("~Low Cap
Count", "C<SPAN
class=290174313-20042004>");
To
simply replace the value I do not think a loop is needed , instead use
IIF...
X=IIf(CC >
1.08<FONT color=#282828
size=2>*Ref<FONT face=Arial
color=#282828 size=2>(CC<FONT
face=Arial color=#282828 size=2>,-<FONT face=Arial color=#ff00ff
size=2>1)<FONT color=#282828
size=2> OR<FONT
color=#282828 size=2> CC < 0.92<FONT
color=#282828 size=2>*<FONT face=Arial color=#0000ff
size=2>Ref(<FONT
color=#282828 size=2>Cc<FONT face=Arial color=#282828
size=2>,-1<FONT face=Arial
color=#282828 size=2>),<FONT
color=#0000ff size=2>Ref(cc,-<FONT
color=#ff00ff size=2>1),cc);
Which states "if cc
is greater than 1.08 times yesterdays value OR if cc is less than .92*yesterdays
value THEN X= yesterdays value ELSE use today's value"
You can use X in
calculations or simply plot it as I did below....
<FONT
color=#282828 size=2>
Cc = Foreign<FONT
size=2>("~Low Cap Count", <FONT
size=2>"C");
X=<FONT color=#0000ff
size=2>IIf(CC > <FONT color=#ff00ff
size=2>1.08*<FONT face=Arial
color=#0000ff size=2>Ref<FONT face=Arial color=#282828
size=2>(CC<FONT face=Arial
color=#282828 size=2>,-<FONT face=Arial color=#ff00ff
size=2>1)<FONT color=#282828
size=2> OR<FONT
color=#282828 size=2> CC < 0.92<FONT
color=#282828 size=2>*<FONT face=Arial color=#0000ff
size=2>Ref(<FONT
color=#282828 size=2>Cc<FONT face=Arial color=#282828
size=2>,-1<FONT face=Arial
color=#282828 size=2>),<FONT
color=#0000ff size=2>Ref(cc,-<FONT
color=#ff00ff size=2>1),cc);<FONT
color=#0000ff size=2>
Plot(x,<FONT color=#ff00ff
size=2>"Corrected Composite",<FONT
color=#ff00ff size=2>4,<FONT
color=#ff00ff size=2>1<FONT color=#282828
size=2>);

[amibroker] Help with a Composite Filter
Hi Jayson,
Thanks for the reply. I caught the missing quotes
right after sending the e-mail.
What I'm trying to do is to erase a bad value in the
composite and replace it with the previous value hence the assignment in the
last line (which doesn't work). I am now trying to replace the composite
array with the 'corrected' cc array as I don't know how to replace a single
element in the composite.
thanks again

<FONT face=Arial color=#0000ff
size=2>Lou,
<FONT face=Arial color=#0000ff
size=2>Your error comes from a syntax error in line 1. note that field
information in a foreign call requires quotes, so..
Cc = Foreign(<FONT
color=#ff00ff>"~Low Cap Count", <SPAN
class=049193703-20042004>"C<SPAN
class=049193703-20042004>", fixup =
0);
I am a bit lost as to what
you are trying to do in the last line but for one thing you would need to
make an assignment, something like X=bla, bla. that in its self does not fix
the problem. What are you trying to do??
Regards,Jayson

with a Composite Filter
I want to filter a composite to get rid of
irregularities caused by bad data. The following code does not
work. The first line gives a "bad arguments" error so I havn't
gotten beyond it yet. There is also a question on the validity of
the last line assigning a value from cc[i] to the composite. Any
help or thoughts would be appreciated.
