Price Alerts

Alert Types Overview

ChartingLens offers multiple alert types designed to cover every scenario a trader encounters. Whether you want a simple notification when a stock hits a price level or a complex multi-condition alert that combines indicators across different timeframes, the alert system has you covered.

Price Target Alerts

The most straightforward alert type. You set an exact price, and ChartingLens monitors the stock in real time. The moment the bid or ask price reaches your target level, the alert fires.

Price target alerts work in both directions. You can set an alert above the current price to catch a breakout, or below the current price to catch a pullback to a support level. Many traders use price target alerts to:

• Wait for a better entry — if a stock is at $150 but you want to buy at $142 near support, set a target at $142 and wait
• Catch breakouts — if a stock is consolidating below $200 resistance, set a target at $201 to be notified when it breaks through
• Monitor exits — set a target at your profit goal so you know when it is time to take gains
• Track stop levels — set a target at your mental stop-loss level so you can react quickly if the trade moves against you

Percentage Change Alerts

Sometimes you do not have a specific price in mind — you just want to know when a stock makes a significant move. Percentage change alerts let you set a threshold like "alert me if AAPL moves 5% up or down from its current price."

This alert type is especially useful for monitoring positions during earnings season, when stocks can make large overnight moves. You can also use percentage alerts on your watchlist stocks to catch sudden momentum shifts that might signal a trading opportunity.

When you create a percentage alert, you choose the direction (up, down, or both) and the percentage threshold. The alert calculates the target price automatically based on the stock's current price at the time of creation and fires when that level is reached.

Indicator-Based Alerts

Indicator alerts go beyond simple price monitoring. They allow you to set conditions based on the technical indicators you use in your analysis — and get notified when those conditions are met without having to watch the chart constantly.

RSI Alerts

Set alerts when RSI crosses above or below a specific threshold. Common uses include alerting when RSI drops below 30 (oversold — potential buying opportunity) or rises above 70 (overbought — potential reversal or exit signal). You can set the RSI period to match your preferred settings.

MACD Cross Alerts

Get notified when the MACD line crosses above or below the signal line. A bullish MACD cross is one of the most widely used momentum signals, and catching it in real time means you can enter a trade at the start of a new move rather than chasing it after the fact.

Stochastic Cross Alerts

Alert on Stochastic %K/%D crossovers, particularly in oversold (below 20) or overbought (above 80) territory. Stochastic crosses in extreme zones tend to produce higher-quality signals, and these alerts let you capture them without constant chart monitoring.

Trendline Alerts

Trendline alerts are a Premium feature that brings your chart annotations to life. After drawing a trendline on the chart — whether it is a support line, resistance line, channel boundary, or any other linear level — you can attach an alert to it.

You have two trigger options for trendline alerts:

• Price Cross — the alert fires the moment price touches or crosses the trendline, even intrabar. This is ideal for aggressive entries where you want to catch the exact moment of a breakout or breakdown.
• Candle Close — the alert fires only when a full candle closes beyond the trendline. This reduces false signals caused by wicks that briefly penetrate the trendline before reversing. Many traders prefer this option for more reliable breakout confirmation.

Because trendlines are diagonal (they move over time), trendline alerts automatically adjust their trigger level with each new bar. This makes them far more powerful than static price alerts for tracking ascending support lines, descending resistance, and channel boundaries.

Visual Alert Lines on Chart

Every active alert is displayed directly on the chart as a dashed horizontal line at the alert level. This gives you immediate visual context — you can see exactly where your alerts are relative to the current price, support and resistance levels, and your other technical analysis.

Alert lines are color-coded by type, making it easy to distinguish between different alert conditions at a glance. You can click any alert line to edit or delete it without opening a separate alert management panel. When an alert fires, its line flashes briefly and then changes appearance to indicate it has been triggered.

Email Notifications

Premium users receive email notifications when alerts fire. This means you do not need to have ChartingLens open in your browser to stay informed. Whether you are away from your desk, in a meeting, or focused on other work, the alert system will reach you via email with all the details you need.

Each email notification includes the stock symbol, the alert condition that was met, the current price, the time the alert triggered, and a direct link to open the stock's chart in ChartingLens so you can take action immediately.
