Alerts

Alerts notify you when specific market conditions are met, so you do not need to watch the chart continuously. Cluster Terminal supports two categories of alerts: price alerts on drawing tools and indicator-based alerts. Both produce audible sound notifications and visual indicators when triggered.

​
Overview

​
Price Alerts on Drawing Tools

Three drawing tools support price alerts:

​
Setting Up a Price Alert

1

Draw the line

Select the Horizontal Line (H), Trend Line (T), or Ray (R) tool and draw it on the chart at your target price level.
2

Enable the alert

Right-click the drawing to open its context menu, then select Enable Alert (or click the bell icon in the drawing properties panel).
3

Configure conditions

Choose the alert condition:
  • Cross — triggers when price crosses the line in either direction
  • Above — triggers when price moves above the line
  • Below — triggers when price moves below the line
4

Set alert mode

  • Once — triggers one time, then disables itself automatically
  • Repeat — triggers every time the condition transitions from false to true
5

Choose sound

Select an alert sound from the available synthesized tones. Different sounds help distinguish between alerts.

​
Alert Conditions Explained

For Trend Lines and Rays, the alert level changes over time as the line extends. Price is compared against the line’s value at the current bar’s time coordinate, not a fixed price.

​
Alert Modes

Place horizontal lines at key support/resistance levels with “Cross” alerts to get notified when price reaches your levels of interest, even when you are away from the screen.

​
Indicator Alerts

18 indicators support built-in alerts. Each indicator defines specific alert events relevant to the type of analysis it performs. Indicator alerts are configured through the indicator’s settings panel.

​
Indicators with Alert Support

​
Enabling Indicator Alerts

1

Open indicator settings

Click the indicator name or gear icon in the indicator panel to open its configuration.
2

Navigate to Alert Rules

Scroll to the Alert Rules section within the indicator settings. This section lists all available alert events for this indicator.
3

Enable desired events

Toggle on the alert events you want to receive. Each event has its own enable/disable switch.
4

Choose alert sound (optional)

Select a sound for this indicator’s alerts. Using a different sound per indicator helps identify the source audibly.
5

Save settings

Close the settings panel. Alerts are active immediately.
Not all indicators support alerts. The table above lists all 18 indicators with alert capability. For indicators not listed, you can use price alerts on drawing tools as an alternative.

​
Alert Event Types

Different indicators use different event types depending on what they measure:

​
Alert Behavior

When an alert triggers, two things happen simultaneously:
  • Sound: A synthesized sound notification plays through your system audio
  • Visual: The triggering element is highlighted on the chart and/or a badge appears in the toolbar
Alert sounds are generated internally using the Web Audio API — no external sound files are required. Multiple sound types are available with different tonal characters (ping, chime, alarm, etc.).

​
Sound Configuration

Ensure your system audio is not muted if you rely on alert sounds. The terminal cannot override system-level mute. Test your alerts after configuring them to confirm you can hear the notifications.

​
Alert History

Triggered alerts are logged with an alertTriggeredAt timestamp. This lets you review when alerts fired, even if you were not watching the screen at the time.

​
Combining Alerts for High-Probability Setups

The real power of alerts emerges when you combine price alerts with indicator alerts:

​
Support Level + Absorption

  1. Draw a horizontal line at a key support level
  2. Set a “Price Below” alert (once) on the line
  3. Enable new_signal alerts on Absorption Alpha
  4. When both alerts fire near the same time, you have a support test with confirmed absorption — a high-probability long setup

​
Trend Line Break + Market Structure

  1. Draw an ascending trend line under a bullish structure
  2. Set a “Cross” alert on the trend line
  3. Enable BOS/CHoCH alerts on Market Structure
  4. A simultaneous trend line break and BOS signal confirms the trend change

​
Bollinger Band + RSI Divergence

  1. Enable “price touches lower band” on Bollinger Bands
  2. Enable “new bullish divergence” on RSI Divergence
  3. Price touching the lower band while RSI shows bullish divergence signals a mean-reversion setup
Start with a small number of alerts and add more as you learn which signals are most relevant to your strategy. Too many simultaneous alerts create noise that is harder to act on than a few well-chosen ones.

​
Limitations

Because alerts are evaluated on candle close (not every tick), very fast price spikes that cross and return within a single candle may or may not trigger depending on where the candle closes. For tick-level precision, monitor the DOM panel directly.
