Hi Chuck,
would the following help? If yes, I can send you
a
beta of the plugin. <FONT
face=Arial>But, it is a beta and not certified
yet by amibroker.com.
I'm open for more useful additions to the
plugin.
UM
/* ABtool.AFL for private plugin
ABtool.DLL Demonstrates the use of some of the following AFL
extension functions of the plugin "ABtool.DLL" (still beta
version!). You should set "ApplyTo current stock" and "n last
quotes n=1" before starting such a script.
STRING TickerFirst(NUMBER
watchlistnum);
// gets first ticker in the WL (eventually put all to a WL to use
this) STRING TickerNext(NUMBER
watchlistnum); STRING TickerPrev(NUMBER
watchlistnum); STRING TickerLast(NUMBER
watchlistnum); NUMBER TickerCount(NUMBER
watchlistnum = -1); // -1 means all
tickers in the database
NUMBER FileOpen(STRING filename,
STRING mode); // mode: "r", "w",
"a" NUMBER FileClose(NUMBER
filehandle);
// filehandle was returned by FileOpen() NUMBER
FileWriteStr(STRING str, NUMBER filehandle);
STRING FileReadLine(NUMBER
filehandle);

Filter = true;

filename
nTickerWL = TickerCount(WL);AddColumn(nTickerWL,
"TickersInWL", 1);
nTickerAll = TickerCount();AddColumn(nTickerAll,
"TickersAll", 1);
// write all tickers in WL to a filefh = FileOpen(fname,
"w");ticker = TickerFirst(WL);FileWriteStr(ticker + "\n", fh);fEnd =
false;while (!fEnd) { ticker =
TickerNext(WL); if (ticker !=

something better than that

Subject: RE: [amibroker] Looping through
"foreign" files
<FONT
face=Arial>
I'll
partially answer my own question by asking another. Perhaps it
might give someone an idea for helping me.
<FONT face=Arial color=#0000ff

Is
there some way to access a text file from within a loop? The
text file could contain all of the tickers that I want to access in the
loop. Or... do I need to write a dll to do
this?

[amibroker] Looping through "foreign" files
<FONT face=Arial color=#0000ff
size=2>The time has come for me to find a better way of looping through
thousands of foreign files.
<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff

stocks in that watchlist within a loop.
<FONT face=Arial color=#0000ff

If
the "foreign" statement would accept a stockID number instead of a ticker, I
could probably make a decent loop to do the job. But, alas,
that's not how it works.

<FONT face=Arial color=#0000ff

appreciated.
