Fair Value Gap Lifecycle Navigator
- Indicators
- Version: 1.0
- Activations: 15
DESCRIPTION
Fair Value Gap Lifecycle Navigator is a chart-based indicator for observing price imbalances and how they develop after formation. It identifies three-candle bullish and bearish Fair Value Gaps on the chart timeframe, then updates their status as subsequent closed candles interact with each price zone.
Instead of treating every gap as a permanent rectangle, the indicator distinguishes fresh, touched, midpoint-tested, filled and invalidated zones. The detection criteria, historical range, number of tracked zones and display behavior can be adjusted for the market being studied.
MAIN FEATURES
- Bullish and bearish FVG recognition using completed three-candle patterns.
- Optional middle-candle directional impulse and body-to-range filter.
- Minimum gap-size filter in points and relative to average candle range.
- Zone lifecycle: Fresh, Touched, Midpoint, Filled or Invalidated.
- Custom-colored chart rectangles, with optional display of resolved zones.
- Dashboard showing active zones, zone state counts and the nearest active gap relative to the last closed price.
- Optional alerts for formation, midpoint tests and completed resolutions.
- Six CopyBuffer outputs for formation events and nearby bullish/bearish zone boundaries.
- Incremental processing when a new candle closes, with full reconstruction after a history refresh.
- No trade execution, DLL, external libraries, web requests or third-party licensing.
HOW GAP DETECTION WORKS
A bullish FVG is formed when the low of the third completed candle remains above the high of the first candle. A bearish FVG is formed when the high of the third completed candle remains below the low of the first candle. The middle candle can also be required to move in the same direction as the gap.
The indicator uses completed bars for formation and for transitions between states. A gap is therefore not declared on an unfinished candle. Historical zone status is updated by later price action as part of the design; the indicator does not claim that zones remain unchanged after creation.
ZONE PHASES
Fresh: No subsequent completed candle has entered the zone.
Touched: The zone has been entered, without reaching its midpoint.
Midpoint: Price has reached at least 50% of the zone, without completing a fill or invalidation.
Filled: Price has crossed the far boundary of the zone, without closing beyond it.
Invalidated: A completed candle closes beyond the far boundary. This takes precedence over Filled on that candle.
DISPLAY AND ALERTS
Users may select whether completed zones remain visible and whether formation marks appear. Dashboard readings refer to the last completed candle. Alerts are optional, grouped into a compact message, and triggered only after new completed candles; historical reconstruction does not generate alerts.
