AbsoluteStrenghtHisto_v1_002
Download scriptThe AbsoluteStrength indicator is designed to provide a visual representation of market sentiment by measuring the relative power between buying pressure (Bulls) and selling pressure (Bears). Instead of just showing price action, it calculates the "strength" of each side to help traders identify which force is currently dominating the market.
Core Logic and Methodology
The script operates by processing market data through several distinct layers:
1. Data Calculation Modes The indicator can interpret market strength in two different ways depending on the user's selection:
- RSI Method: This approach looks at the immediate change in price between the current period and the previous period. It isolates whether the price moved up or down and quantifies that momentum.
- Stochastic Method: This approach takes a broader view by looking at the highest highs and lowest lows over a specific timeframe. It measures where the current price sits relative to that range—essentially determining if the price is "stretched" toward the top (buying strength) or the bottom (selling strength).
2. Smoothing and Averaging Raw market data is often "noisy" and erratic. To create a reliable trend, the script applies multiple layers of mathematical smoothing:
- It first calculates base values for both Bulls and Bears.
- It then applies a Moving Average to these values to filter out minor price fluctuations.
- A final smoothing pass is applied to ensure the resulting lines are fluid and representative of the broader trend rather than instant spikes.
3. Visualization Styles (Histogram Logic) The script offers several ways to display this "strength" data on your chart, allowing you to choose the visual style that best fits your trading strategy:
- Standard Smoothing: Displays the calculated bull and bear strengths as distinct lines.
- Opposite Symmetry: Adjusts the values so they mirror each other, making it easier to see the balance of power (when one side goes up, the other reflects downward).
- Dominance Tracking: Highlights which side is winning. In these modes, the indicator identifies the stronger force and displays it prominently while neutralizing the weaker force (setting it to zero). This provides a clear "winner-takes-all" visual of the current market sentiment.
Summary for the User
In simple terms, this script acts as a momentum scale. It looks at price movement (either through immediate change or relative range) and decides who is "winning" the tug-of-war: the buyers or the sellers. By smoothing this data, it removes the "jitter" of the market to show you a clear, readable trend of absolute strength.
