This script is a multi-layered technical analysis tool designed to identify significant price movements and structural "swings" in the financial markets. It utilizes a three-level approach to help traders visualize market trends across different time horizons simultaneously.
Core Functionality
The tool functions by identifying local highs and lows—specifically looking for price points that stand out from the immediate surrounding data. Instead of showing every minor price fluctuation, it filters out "noise" to highlight only the most significant structural peaks and valleys.
The Three-Level Logic
The script operates on three distinct layers of analysis, which can be thought of as different "zoom levels" for the market:
- Fast Level (Short-term): This captures quick, immediate price movements. It reacts rapidly to current market volatility to show where the price is pivoting in the very near term.
- Medium Level (Intermediate): This identifies broader trends that develop over a slightly longer period. It filters out the minor "jitters" of the fast level to show more stable structural changes.
- Slow Level (Long-term): This represents the macro view. It ignores almost all short-term volatility, focusing only on the major historical highs and lows that define the overall direction of the market over a significant period.
Key Technical Behaviors
To ensure the data presented is clear and professional, the script employs several specific logical rules:
- Deviation Filtering: The tool does not mark a new peak or valley unless the price has moved by a specific "distance" (deviation). This prevents the chart from being cluttered with insignificant price ticks.
- ZigZag Smoothing: It utilizes logic similar to a "ZigZag" indicator, where it constantly re-evaluates whether a new high is higher than the previous one or if a current move is still part of the same trend. If a new, higher peak is formed, it "cuts" the previous minor peak to keep the visual path clean and continuous.
- Visual Offsets: To ensure that the different levels do not overlap or appear as one single line, the script applies small visual offsets (deltas). This creates a clear separation between the fast, medium, and slow signals on your screen.
- Dynamic Calculation: The logic automatically adjusts based on the "Periods" you set. By changing these values, you can customize how much historical data the tool looks back at to decide what qualifies as a significant move.
Summary for the User
Essentially, this script acts as a structural map. It takes the messy, constant movement of live price action and distills it into three distinct layers of "landmarks." By looking at these landmarks, a trader can see not just where the price is now, but also the broader structural path the market has taken, helping to identify major support and resistance zones across different timeframes.
