Interactive Brokers Price Alerts guide

For a buy-and-hold investor, alerts are mainly a monitoring tool rather than a trading signal. Typical uses include being notified when a stock you want to buy falls to a target price, when a holding moves sharply in either direction, or when an index crosses a level that prompts you to review your allocation. Alerts do not place trades by themselves in most setups; they simply prompt you to look. That separation is useful for long-term investors because it creates a pause between market movement and action, reducing the chance of impulsive decisions. Decide in advance what you will actually do when an alert fires, and write that plan down.

Alert behaviour varies by platform, so confirm the details in Interactive Brokers' current documentation rather than assuming features exist. Key questions include which platforms support alerts, which conditions can trigger them, how notifications are delivered, whether there are limits on the number of active alerts, and whether alerts expire after a set period. Also check whether alert prices are based on last trade, bid, ask or another reference, since this affects when they fire. Test any alert setup with a non-critical example before depending on it for decisions that matter to your portfolio.

Alerts are helpful but not guaranteed. Notifications can be delayed by network issues, device settings or platform outages, and an alert firing is not the same as an order executing at that price. If a fast decision genuinely matters to your strategy, consider whether an actual order type is more appropriate than an alert, and verify how the broker handles that order type. Alerts themselves are often free, but confirm this in the current fee schedule, and remember that acting on alerts creates trading costs you can estimate with the Brokerage fee calculator (/tools/brokerage-fee-calculator). For broader context, see the Long-term investing hub (/invest-long-term) or work through Find my broker (/find-my-broker) if alert functionality is a deciding factor in your broker choice.
