What is Grail Indic Indicator?
Grail Indic is an MT4 indicator that combines semafor-style pivot markers with high and low trendlines and Fibonacci retracement displays. The chart annotations organize swing structure and make the selected reference areas easier to review.
Settings control pivot sensitivity, line extension, stored pivot counts, colors, widths, and optional text or sound notifications. The annotations describe displayed chart structure rather than a fixed market outcome.
How to Use It in Practice
Use the plotted structures as visual references during chart review:
- Add Grail Indic to an MT4 chart and review the high, low, and lowest semafor markers.
- Use the HTL and LTL settings to control high and low trendline display and extension.
- Compare the displayed Fibonacci references with recent swing structure.
- Adjust pivot sensitivity, line colors, widths, and optional alert settings for readability.
Semafor markers, trendlines, and Fibonacci references appear in one chart view, while the existing settings provide control over sensitivity, styling, extension, and notifications.
