Brian,

 

This looks way complex.  I’m assuming that are running this as a scan or exploration.  Maybe I’m missing something, but why not do the following:

 

// clear Watchlist
iDestinationWatchlist = 63;

 

CategoryRemoveSymbol( “”, categoryWatchlist, iDestinationWatchlist);

bCondition1 = false;

bCondition2 = false;

bCondition3 = false;


bCondition1 = LastValue( C > MA( C, 50 ) );

bCondition2 = LastValue( V ) > 100000;

bCondition3 = LastValue(MACD()) > 0;

Filter = 0;

If (bCondition1 and bCondition2 and bCondition3)
      {

CategoryAddSymbol( "", categoryWatchlist, iDestinationWatchlist);
Filter = 1;

}

 

AddColumn(RSI(),"RSI");

This is pseudo-coded and very rough, but I think it will do what you want.

 

Regards,

 

Dan.

So, here is what I have so far. I am weeding out what actually
works, from what does not work. One script works, another does not --
which is why I am posting once more.

This actually does clear all symbols within a specific watchlist, at
one time. Place the code at the top of your Exploration AFL.

// clear Watchlist
varWatchlistNumber = 63;// select a watchlist by using its number
ClearList = GetCategorySymbols(categoryWatchlist,
varWatchlistNumber);
for( i = 0; ( symC = StrExtract(ClearList, i) ) != ""; i++ )
{
CategoryRemoveSymbol( symC, categoryWatchlist, varWatchlistNumber );
}

On the other hand, getting the tickers that appear in my AA results
window and putting them into the same watchlist that was just
cleared, is another story. I've tried numerous scripts. Here are
three original (scoured the archives) examples of what I have
tried... note that the conditions do not represent my
actual "Filter" conditions. I end up with the last ticker from the
scanned watclist, which appears in the new watchlist (#63). No other
tickers are captured. What is wrong?

/// ADD SYMBOLS TO WATCHLIST ///
Condition = LastValue( C > MA( C, 50 ) );
ticker = Name();
wlnumber = 1;
EnableScript("jscript");
<%
if( AFL("condition" ) )
{
AB = AFL.CreateObject("Broker.Application");
AB.Stocks( AFL("ticker" ) ).WatchListBits |= 1 << AFL( "wlnumber" );
}
%>
Buy=0;
(Use View->Refresh All to refresh symbol list.)

/// ADD SYMBOLS TO WATCHLIST ///
// the code adds symbols with last day volume > 100000
// to the watch list number 1
if( LastValue( V ) > 100000 )
{
CategoryAddSymbol( "", categoryWatchlist, 1 );
}

/// ADD SYMBOLS TO WATCHLIST ///
ORigin=0;
destination=12;
CategoryRemoveSymbol( "", categoryWatchlist, destination );
Filter = InWatchList(ORigin) AND MACD()>0;
AddColumn(RSI(),"");
CategoryAddSymbol( WriteIf(Filter,Name(),"xyz"), categoryWatchlist,
12 );
//Hit View->RefreshAll


None of these last three scripts work. I've tried several variations
that make sense to me, but still do not work. Any ideas or examples?
Once I get something that works, I will post these in the AFL
library.

Thanks in advance!

Brian
