Detects and draws consecutive zero-print tick zones — bid-only or ask-only price levels
Zero Print Zones detects consecutive zero-print ticks (bid-only or ask-only) and draws them as rectangle zones on the chart. These zones represent one-sided liquidity gaps in the order book — areas where only buyers or only sellers were present.
For each bar within the session window, the study examines Volume-at-Price data. A "zero print" tick is one where either:
When a configurable number of consecutive zero-print ticks are found, a zone is created. Bar extremes (high/low) are excluded as they are natural boundaries, not true zero prints.
Creation: Zones are detected during the configured session window and drawn as filled rectangles extending to the right edge of the chart.
Removal (default mode): When price later intersects a zone, the zone is automatically deleted. This keeps the chart clean — only untested zones remain visible.
Persistent mode: With "Keep Zones on Intersect" enabled, zones are never removed and always extend to the chart edge, regardless of price action.
