Download script
This script functions as a dynamic trend-tracking indicator designed to identify and visualize market movements based on structural highs and lows. Rather than using standard lagging averages, it analyzes the relationship between consecutive price bars to determine the prevailing momentum of the market.
Core Logic Overview
The primary objective of the script is to detect whether the market is currently in an "Up Trend" or a "Down Trend" by monitoring specific price actions. It accomplishes this through the following logic:
1. High and Low Tracking The script scans each historical bar to identify "Maximums" (Highs) and "Minimums" (Lows). It keeps a running tally of these occurrences. Instead of simply looking at the last price, it evaluates whether a new high or low is actually breaking out beyond the previous boundaries.
2. Trend Validation via Counting
The script uses a user-defined threshold (the GSv_tend parameter) to validate a trend. A trend change is not triggered by a single erratic movement; instead, the script waits until a specific number of consecutive high or low movements occur. This helps filter out "market noise" and ensures that only sustained movements are recognized as significant trends.
3. Dynamic Trend Switching
- Upward Movement: If the price consistently establishes new highs reaching the required threshold, the indicator identifies an upward trend.
- Downward Movement: If the price consistently establishes new lows reaching the required threshold, the indicator identifies a downward trend.
- Internal Bars: The logic intelligently ignores "internal" bars—those that do not break the previous high or low—ensuring that the trend stays stable unless a clear structural change occurs.
4. Visual Mapping Once a trend is confirmed, the script maps these movements onto your chart. It identifies specific starting and ending points for the trend lines:
- When an Up Trend is confirmed, it marks the transition from a significant low to a new high.
- When a Down Trend is confirmed, it marks the transition from a significant high to a new low.
Summary for the User
Essentially, this tool acts as a structural "map" of price action. It watches the market's "peaks" and "valleys," ignores small fluctuations that don't break those peaks/valleys, and only draws a trend line once the market has proven its direction by hitting a specific amount of consecutive structural milestones. This allows traders to see the "bones" of the market movement clearly.
