|
* bin/screen.js — Market Screener CLI
|
|
*
|
|
* Fetches today's catalyst tickers from Yahoo Finance news,

|
* and saves a full HTML report.
|
|
*
|
|
* Usage:
|
|
* npm start → Yahoo news → catalyst tickers → screen
|
|
* npm start -- watch → default watchlist
|
|
* npm start -- AAPL MSFT VOO → specific tickers
