What price alerts do and why the details matter
A price alert is a notification, not an order. When the market touches your chosen level, the platform sends a message, but nothing is bought or sold unless you act or have a separate order in place. For long-term investors, alerts are commonly used to flag rebalancing levels, unusual moves in a core holding, or entry points for planned additions. Because an alert only helps if it arrives reliably and on time, the delivery mechanics deserve as much attention as the feature itself.
- An alert notifies you; it does not execute a trade on its own.
- Alerts can be based on last price, bid or ask depending on the platform, which affects when they trigger.
- Delivery can fail silently if an app is logged out, notifications are disabled or a device is offline.
- Alerts are a monitoring aid, not a substitute for orders such as limits or stops.
