Volume Stack with Dollar Volume Score

This script is designed to analyze candles for buy/sell pressure, volume flows, and generate intuitive emoji-based signals. Its core function is to help traders visually and quantitatively interpret price and volume behavior for potential bullish, bearish, or neutral market states.

Key Features and Logic
Price Range Analysis: Calculates the candle's price range and determines the proportion of volume attributed to buyers and sellers using buy_percent and sell_percent.

Market State Classification:

Bullish/Bearish/Neutral: Based on buy/sell percentage comparisons.

Strong Signals: Flags when buy/sell pressure exceeds defined thresholds (≥0.75).

Transitions: Detects when states shift sharply (e.g., from bull to strong bear).

Visual Cue System:

Uses different emojis (📈, 📉, 🚀, 🔥, 💎, 💀, ❌) to mark normal, strong, transition, and neutral signals for easy chart interpretation.

Dollar Volume Calculation: Multiplies close price by volume to derive "dollar volume" per bar. Normalizes this with a moving average for context-sensitive spike detection.

Scoring Mechanism:

Dollar Volume Score: Evaluates the normalized change in dollar volume, assigning scores for strong (±2), mild (±1), or neutral (0) changes.

Buy/Sell Pressure Score: Calculates a simple pressure score based on buy/sell proportions for each candle.

Composite Score: Combines both scores to define the overall bullish/bearish/neutral state.

State & Emoji Plotting:

Plots respective emojis at the chart bottom depending on composite score and state (bullish, bearish, strong moves, transitions, neutral).

Alerts:

Sends alerts for key transitions (like bull-to-strong-bear), strong moves, and neutral states, aiding automated signal handling and decision-making.
