Watchlists are central to the CityFALCON experience, so of course we've added capabilities to interact with watchlists from voice. You can also get financial news on a single topic, even if it is not on your watchlist.
If you want stories for a particular topic, say What are the top stories for Amazon, and you will hear about Amazon's latest news. If the topic you want to ask about is a specific stock, you can even use the ticker, like F-B or A-M-Z-N. On the other hand, if you have a watchlist called My Tech Stocks, you can ask What are the top stories on My Tech Stocks watchlist, and we will answer with the latest news for that watchlist.
Make sure you use the keyword "watchlist" if you want stories from a watchlist, as sometimes Alexa cannot determine exactly what you mean. Voice recognition software is still pretty young, so sometimes it gets confused.
This brings about a good point: if you will often access CityFALCON's services via voice, we strongly recommend using unique names for your watchlists. If you have a watchlist called Gold, when you ask What are the top stories for Gold, we cannot determine if you mean the commodity gold or your watchlist Gold. Visually it is easy to determine because of placement, colors, and design decisions, but via voice, it can be confusing.
If you want to filter your stories, you can do that too. See here for the filter options.
