This function parses a symbol custom database and returns a value of one on bars where the database field data contain a specific word.
This function accepts three parameters. The first one is the database name (Example: ' yahoo_news ' if you are using the yahoo news downloader - Yahoo News), the second one is the field name (Using the same downloader, it should be 'title') and finally the last parameter is a list of the words we are searching for. You can add one or many words by separating them with a comma.
Here is an example: (This function's name is 'ContainsWords')
indicator1 = ContainsWords('yahoo_news', 'title', 'Buy,Jump,Big,Rise');
In addition, here is a snapshot of the 'yahoo_news' database for the stock symbol 'aa':
