This script is a specialized market analysis tool designed to visualize the intensity and activity level of a financial market. Instead of showing price directly, it translates raw market movements into three distinct percentage-based metrics, allowing traders to see how "active" or "volatile" the market is at any given moment.
The logic operates through three primary components:
1. Aggressiveness (Blue Line)
This metric measures the speed and strength of price movement. The script examines a set period of recent bars to determine how much the price is pushing in a specific direction. It calculates the net displacement of the price, essentially distinguishing between "pushing" movements and "receding" movements. By normalizing this data into a percentage, it shows you how aggressively the market is trying to move toward a certain target.
2. Volatility (Red Line)
This metric focuses on the consistency and variance of price actions rather than just the direction. It uses a standard deviation logic, which looks at how much the current price fluctuates away from its recent average. A high percentage here indicates that the market is "noisy" or experiencing wide swings, while a low percentage suggests that prices are staying very close to their moving average.
3. The Middle Average (Dark Green Line)
This is a balanced overview of the market state. It takes the results from both the Aggressiveness and Volatility metrics and calculates their mathematical mean. This provides a single unified "activity score" that combines both the intensity of the trend and the variance of the price movements into one readable line.
Key Technical Behaviors
- Percentage Scaling: All three metrics are scaled to a 0–100% range. This makes it easy for users to understand the market state at a glance—the higher the lines, the more active the market is; the lower the lines, the "quieter" or calmer the market remains.
- Dynamic Recalculation: The script includes an option to either update the data in real-time with every tick (providing a live, moving view) or lock the values once a candle is closed (providing a more stable, historical view).
- Historical Buffer: The tool maintains a "memory" of recent market data. By keeping a buffer of past movements, it can accurately calculate current percentages based on relative highs and lows, ensuring that the percentages remain meaningful even as market conditions change rapidly.
