Download script
This script is a specialized technical analysis tool designed to identify and visualize significant price movements, specifically focusing on "peaks" and "troughs" (highs and lows) within a financial chart. Instead of relying on standard moving averages or simple momentum oscillators, it uses a logic system inspired by structural price action to determine where the market is trending and where it might be reversing.
Core Logic Overview
The tool works by scanning each candle in the historical data to identify "Extreme Points." It doesn't just look for any high or low; it seeks out significant structural breaks. The script evaluates whether the current price is breaking out of a defined range or establishing a new local boundary.
Key Components of the Analysis
1. Extreme Point Identification The script maintains a memory of the highest and lowest prices reached over a recent period. It constantly compares the current candle's high and low against these stored boundaries:
- If a new price exceeds the previous "High," it marks a potential peak.
- If a new price drops below the previous "Low," it marks a potential trough.
2. Trend and Sentiment Tracking Beyond just identifying highs and lows, the script analyzes how the price reached those points. It looks at:
- Opening vs. Closing Prices: It checks if a candle opened at a new high but closed lower, or vice versa, to determine the strength of the move.
- Relative Positioning: If a price is neither clearly at a high nor a low, the script calculates which boundary it is closer to (using mathematical distance) to assign it a logical "leaning" towards one side or the other.
3. Breakout and Reversal Detection
The logic includes a specific "tendency" filter (controlled by the GSv_tend parameter). This helps smooth out market noise:
- It tracks sequences of movements to ensure that a single erratic candle doesn't trigger a signal.
- It identifies "breakthroughs," where price moves significantly enough to reset the internal counters, signaling a shift from one trend (e.g., bullish) to another (e.g., bearish).
4. Visual Representation Once the logic confirms a significant structural high or low:
- The script draws visual markers on the chart (simulating a ZigZag-style movement).
- It connects these points to provide a clear "skeleton" of the price action, making it easier for a user to see the underlying market structure without being distracted by minor fluctuations.
Summary for the User
Essentially, this tool acts as an automated "structuralist" analyst. It filters out the daily "noise" of the market to show you only the meaningful turning points. By identifying where the price has structurally failed to make new highs or lows and instead pivoted, it provides a visual map of the market's path, helping users identify key support and resistance zones based on historical extremes.
