SNR SND Zones – Support & Resistance, Supply & Demand Zones with Flip Detection and Trade Setup Visualization
SNR SND Zones is a technical analysis tool that combines two complementary concepts into a single indicator: classic Support & Resistance (SNR) levels and Supply & Demand (SND) zones, together with automatic flip-zone detection, zone quality tags, and a visual trade setup (entry, stop loss, and multiple take-profit targets).
Support & Resistance (SNR)
The indicator scans historical price action for swing highs and lows (fractals) and clusters points that repeat around the same price level into Support and Resistance zones. A zone is only drawn once it has been touched a minimum number of times, so only levels with genuine confluence are shown. The lookback period, fractal sensitivity, minimum touch count, and maximum number of zones per side are all adjustable.
Flip Zones (Role Reversal)
When a Resistance level is broken and price closes beyond it, the same zone can flip into a Support level (labeled RBS – Resistance Become Support). The same logic applies in reverse, turning a broken Support level into Resistance (labeled SBR – Support Become Resistance). Flip zones are optional and use their own colors so they remain visually distinct from ordinary Support/Resistance zones.
Supply & Demand (SND)
The indicator also detects Demand and Supply zones by locating a small consolidation “base” followed by a strong impulsive candle that breaks away from it. Impulse strength is measured against the average candle range over a configurable period, and the base must be narrow relative to that average to qualify. Detected zones are labeled with the pattern that formed them (RBR, DBR, RBD, or DBD) based on the direction price was moving before the base formed.
Adaptive Zone Sizing (ATR)
When Adaptive ATR is enabled, the clustering tolerance for Support/Resistance, the visual width of drawn zones, and the stop-loss buffer used in the trade setup are all calculated as a multiple of the current ATR value instead of fixed point values. This keeps zone behavior consistent across different symbols and timeframes without manual re-tuning. Fixed point-based values are used instead when this option is disabled.
Zone Quality Tags
Each zone can optionally be tagged with additional context: a FRESH tag when the zone has not been touched by price since it formed, a Strong tag when the zone originated from a Marubozu-style impulsive candle (based on a configurable body-to-range ratio), and a Sweep tag when the impulse candle shows a liquidity-sweep wick against the breakout direction (based on a configurable wick ratio).
Trade Setup Visualization
When price enters an active, unbroken SNR or SND zone, the indicator plots a directional arrow, a BUY or SELL label with the reference entry price, a stop-loss line placed outside the zone (buffered by points or by ATR), and up to five take-profit lines drawn at the nearest opposing zones. This is a visual reference only — the indicator does not send, modify, or manage any trade orders.
Zone Display & Legend
Zones are drawn as shaded rectangles behind the candles by default so price action stays readable, with optional borders, adjustable opacity, and a minimum-brightness setting so zones remain visible on dark chart backgrounds. Each zone type (Resistance, Support, RBS, SBR, Demand, Supply) uses its own color. An on-chart legend panel can be shown to summarize what each color and code represents, with adjustable position, size, and font.
Summary
SNR SND Zones brings pivot-style Support/Resistance, Supply/Demand order-block zones, and role-reversal (flip) zones together in one indicator, intended for traders who read price structure through key levels and reaction zones. All zone detection parameters, ATR-adaptive sizing, quality tags, trade setup visualization, and display/legend options are configurable through the input parameters. The indicator does not use DLL calls, does not connect to any external service, and does not collect user data.
