Slack Price Alerts
Description
Create a no-code workflow that monitors selected stock, ETF, or fund prices and sends alerts to Slack when a defined condition is triggered. The workflow can run on a schedule, request current prices from FinImpulse, check each result against your rules, and publish a formatted message into a Slack channel.
This setup is useful for teams that want simple market data alerts without building a custom notification system. You can track a watchlist, monitor internal coverage lists, follow selected ETFs, or notify a team when a price moves above or below a configured level.
The alert rules can be stored in Google Sheets, Airtable, or directly inside the workflow. A basic version can check whether the latest price is above or below a fixed threshold. A more advanced version can compare the latest price with a previous value and send alerts based on daily change, percentage change, or selected market status.
The workflow can be built in either n8n or Make. In both versions, the structure is similar: start with a scheduled trigger, read the list of symbols and alert rules, request current prices from FinImpulse, apply a condition, and send a Slack message only when the condition is true.
