PRO Scalper

The PRO Scalper indicator provides an intraday price-action and liquidity map designed to identify immediate market direction by combining volume-weighted fair value, session boundaries, and real-time order-flow proxies. This tool helps scalpers filter market noise by aligning high-probability supply and demand zones with higher-timeframe trend biases and liquidity clusters.

Usage

The PRO Scalper serves as a comprehensive intraday dashboard. It is most effective on 1-minute to 5-minute timeframes for assets like crypto or index futures, utilizing a higher timeframe (such as 15-minute or 1-hour) for trend filtering.

• Trend Continuation: Users can enable the "Only in trend" mode to display zones that align with the EMA and ADX filters. A common setup involves waiting for a pullback into a Demand zone (in an uptrend) that coincides with the VWAP or the Opening Range midpoint, confirmed by bullish Delta Bubbles.
• Liquidity Sweeps: By monitoring price wicks that penetrate zone boundaries but close back inside, traders can identify potential "absorption" scenarios where large players are filling orders, often indicated by a flip in Bubble color.
• Opening Range Breaks: The indicator plots the initial session balance. A breakout of this range accompanied by high-intensity Bubbles indicates institutional intent, with traders often looking for a retest of the range boundary or an adjacent Supply/Demand zone.
• Density Depletion: When a Liquidity Density band is "eaten" (disappears due to high volume), it signals that resting liquidity has been consumed, often leading to rapid price continuation toward the next major level.

Details

The indicator is constructed using five core technical components:

1. VWAP & Opening Range: The VWAP resets daily to provide a "fair value" anchor, while the Opening Range defines the initial auction balance.
2. Dual Supply/Demand Engines: Two independent pivot-based engines (e.g., 10-period and 5-period) run simultaneously to map both macro structure and micro-intraday levels. Zones are adaptively sized using the Average True Range (ATR).
3. Trend & Strength Filtering: A combination of two EMAs provides directional bias, while an optional ADX filter ensures trades are only taken during periods of sufficient trend strength.
4. Delta Proxy Bubbles: Using range-weighted calculations, the script visualizes buying/selling pressure without requiring external tick data. A quantile filter ensures only statistically significant pressure points are displayed.
5. Liquidity Densities: These bands represent clusters of high activity. The script includes a "break condition" logic; if price crosses a density with volume exceeding a specific moving average, the liquidity is considered consumed and the band is removed.

Settings

Core & Trend

• ATR Length: Sets the lookback for the Average True Range used to size zones and densities.
• Opening Range Mode: Choose between "Auto" (multiplies timeframe) or "Manual" minutes.
• Trend Mode: Toggles between EMA-only bias, EMA + ADX strength, or Off.
• Use HTF for filter: Enables higher-timeframe data for the trend and ADX calculations.

Zones & Order-flow

• Pivot Settings (A/B): Defines the left and right bar requirements for the two independent zone engines.
• Zone depth × ATR: Determines the vertical thickness of Supply and Demand boxes.
• Only in-trend zones: Filters out zones that oppose the current EMA/ADX bias.
• Quantile % (Bubbles/Densities): Controls the sensitivity; higher percentages show only the most extreme activity.
• Merge Distance: Defines the proximity at which multiple liquidity densities are combined into one.
• Break Condition: Multiplier for the volume moving average that triggers the disappearance of a density band.

FAQ

How do I interpret the Delta Bubbles? The bubbles represent a proxy for delta pressure based on price movement within the candle. Larger circles indicate higher relative pressure compared to the recent lookback period, with green signifying buying and red signifying selling.

Why do some Liquidity Densities disappear? Densities are programmed to be "eaten." If price moves through a density band with volume higher than the user-defined threshold, it suggests the resting orders have been filled, and the band is removed to signal a potential breakout.
