I think your pricing instincts are directionally correct. They may be off by a bit, but I don't think it's by a magnitude. Perhaps you settle at $15, but I think charging ~$2-5/mo for this would be much too little. Might as well hold at $19 for now and see how it goes. If you can't get early adopters at that price point I don't think pricing is your main concern. The pain is acute enough that any passable product should be in-demand.
For pricing context, FinViz elite (https://finviz.com/elite) costs ~$25/mo. Other, newer tools (Atom, Koyfin) are free. However, these are research tools, not notification tools. Anecdotally, notification tools seem to command higher prices.
I would guess that false negatives are your biggest churn risk. Meaning, subscribers will be angry if your list fails to cover one opportunity that they miss out on.
I think subscribers will (and should) also expect 0 downtime at this price. So, it may be better to focus on reliability over new feature rollouts. In this market, a plaintext email with companies, tickers, and list dates would be a significant upgrade over existing consumer (read: not Bloomberg) alternatives.
