A Trend Extremum Indicator with Sound, Email, and Mobile Alerts

Summary

The document describes a chart indicator that marks recent price highs and lows over a chosen lookback period. These extrema can serve as possible support and resistance areas and help outline a trend channel. It explains how alert functionality can be added to an existing indicator: buy and sell buffers are checked at a selected bar, then sound alerts, email messages, or mobile notifications can be issued. The alert settings include the signal bar, whether each notification type is enabled, and a limit on repeated alerts.

This is an implementation description, not a tested trading strategy. It provides no rules for entering or exiting positions, no performance results, and no evidence that the marked extrema reliably identify support, resistance, or trend changes. The usefulness of the signals depends on the underlying indicator’s calculation and behavior, which is not fully explained in the text. Users would need to validate signal timing and alert handling before relying on it for trading decisions.

Key ideas

• The indicator marks period highs and lows as potential support and resistance points.
• The extrema can be used to sketch a channel around the current trend.
• Buy and sell signal buffers can trigger sound, email, and mobile alerts.
• The alert logic checks a configurable bar and limits repeated notifications.
• The document gives no evidence that the indicator’s signals are profitable or reliable.
