news command doesn't work as documented

Describe the bug
A clear and concise description of what the bug is.

When trying to access news headings then some optional parameters do not work as documented. I used the stocks/news for this and "Feedparser" as my default data source. Optional parameters like --oldest and --date do not seem to have any effect while --limit seems to have. Also, --limit has (low) default value that has not really been documented anywhere and I had to jump into source code to realise it. It also shows no sign there the use of --oldest or --date

To Reproduce
Steps(from the start) and commands to reproduce the behaviour

The usual:
stocks
load AAPL
news
and then
news -o
or
news -d 2023-01-01 -o
return exactly the same result

Additional context
Add any other information that you think could be useful for us.

Problem lies in the poor --help / documentation / missing features that have been documented.
