Stock Alarm sells stock tracking, market alerts, screening, charts, and research tools for traders monitoring several types of market assets. Its $20K a month was founder-reported on the Indie Hackers product page (not independently verified), as of March 2023.

Where it sits in the data

Stock Alarm's $20K a month is higher than 74% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, demand is clearest among traders who monitor stocks, crypto, forex, and other market assets and want alerts outside a standard chart screen. The buyer would be a market participant who follows technical indicators or market events and wants phone, email, push, or sound notifications.

Distribution would have to come through app stores, web search, content, and direct invitations to try the product. The hard parts include maintaining reliable real-time data, supporting several alert channels, operating the research terminal, handling integrations, and managing regulatory and support demands. Competition would come from other market-data and alerting products.

Verdict: Hard to replicate.

One thing to take from it

The product presents one membership across mobile apps, web alerts, and a research terminal. Its strongest sales surface is the breadth of alert types: price conditions, technical indicators, market events, phone calls, emails, push notifications, and custom sounds.
