Price alerts: alert lines, crossing detection and the alert sound

A price alert is a horizontal line armed from the chart context menu. When the live close crosses it, the app plays the Price alert sound once and removes the line. The sound is chosen per event in the Sounds settings.

What it does

An alert is a horizontal line flagged isAlert on the chart's symbol. It is created from the chart context menu: the item Add alert shows the price under the cursor and drops the line there. The renderer draws it in amber (rgba(251, 191, 36)) with a 6/4 dash pattern and a small bell glyph left of the price label, so an armed alert cannot be mistaken for an ordinary support or resistance line.

A watcher mounted on the Rithmic and crypto footprint screens observes each new close. When the previous close and the new close sit on opposite sides of an alert price (or one of them equals it), the alert fires: the Price alert sound plays and the line is removed. An alert fires at most once.

How to use it

  • Right-click the chart at the level you want to watch and choose Add alert; the menu item shows the exact price it will use.
  • Adjust the level by dragging the line or by selecting it and reading the price in the panel. The line is a drawing, so Delete removes it and the trash button clears it with the symbol's other drawings.
  • Choose the sound in Chart settings → Sounds (also on the Settings page): the Price alert row offers the eleven synthesized tones and Off, with a preview button. There is no voice clip for this event.
  • When price crosses, the tone plays once and the line disappears. Re-add the alert if you want to be notified again.

Limits and pitfalls

  • Detection works on closes published by the chart's bar stream, not on every trade. On Rithmic the watcher is fed by the imperative bar feed so a wick that touches the level and returns within the same update is still caught; on crypto it reads the latest close held in React state.
  • Alerts are per symbol. Changing symbol resets the watcher, and an alert on ES does not fire from MNQ prices.
  • The alert is removed when it fires; it is not re-armed automatically and there is no alert history.
  • The alert sound follows the global sound switch and the per-event preference; if either is Off the crossing is silent, but the line is still removed.

Frequently asked questions

Why did my alert fire only once?
An alert is one-shot by design: on the first crossing the sound plays and the line is deleted. Add a new alert to watch the level again.
Can I change the colour of an alert line?
The colour field is present in the properties panel, but the renderer always paints alert lines amber and dashed with a bell glyph so they stay recognisable.
Which sound plays and where do I change it?
The Price alert event, default Bell. Change it in the Sounds tab of the chart settings or on the Settings page; any of the eleven tones or Off can be selected and previewed.
