Hello Trader,
1. The explorer does not throw away stocks that are not up to date -
your formula does.
If you are using ValueWhen( datenum() == 1010907, close ) < 1
and the stock was not traded at all on Fri, 9/07 the ValueWhen
has an EMPTY value. Comparisons to {Empty} gives {empty} or
no signal at all.
You may consider the following day to detect stocks both non-trading and
trading below certain leve:
filter = ValueWhen( datenum() == 1010907, close ) < 1;
filter = IIF( IsEmpty( filter ), 1, filter );
2. AmiFeed - it supports loading external .TLS files now, so you can
generate the list of stocks you want to import - save it as a plain
ASCII text file with .TLS extension and tickers listed one by one in every line
- and then load this TLS file into AmiFeed everytime you want to import quotes.
Best regards,
Tomasz Janeczko
