This script is a Volume Spread Analysis (VSA) tool designed to identify both strength and weakness signals in the market by analyzing volume, candle spread (high-low), and price action context. It helps traders interpret smart money activity and confirm or negate signals with the following candle.

🔍 Key Features:
Volume Analysis:

Uses a moving average (MA) and standard deviation (STD) to assess volume behavior.

Flags high/low volume bars and evaluates their spread (wide/narrow).

Price Action Context:

Evaluates whether the close is near the high, mid, or low of the bar.

Compares the current bar's volume and close to the previous 3 bars to detect trends or reversals.

Signal Detection:

Detects a variety of VSA patterns, including:

Weak Signals: No Demand, Weak Demand, No Supply, Upthrust, Reverse Upthrust, Effort to Fall, Shakeout, Hidden Selling

Strong Signals: Buying Effort, Buying Climax, Selling Climax, Stopping Volume, Test, Spring, Effort to Rise

Each signal is colored differently for visual clarity.

Confirmation & Negation:

Highlights the next candle if it confirms the signal (higher close + higher volume) or negates it (lower close + lower volume).

Confirmation = black bar
Negation = gray bar

Bar & Label Visualization:

Adds color-coded labels above or below candles with signal names.

Allows the option to disable the bar color change while keeping labels active.
