Download script
This script functions as a sophisticated technical analysis tool designed to identify key structural points in financial price action. It focuses on mapping out significant high and low peaks (swings) while analyzing the "momentum" or "tendency" of price movements using a multi-layered logic system.
Core Functionality
1. Structural Peak Detection The script scans historical price data to identify significant highs and lows. Rather than marking every minor fluctuation, it establishes a framework of "active" maximums and minimums. It tracks these points to help traders visualize the overall skeletal structure of the market trend.
2. Trend and Momentum Tracking A primary feature of this script is its ability to count consecutive price behaviors. It maintains internal counters that track sequences of price action. This allows it to recognize when a market is consistently pushing in one direction versus when it is showing signs of exhaustion or reversal.
3. Intelligent Sequence Analysis The logic includes a specialized routine for determining how new peaks are formed. It doesn't just look at whether a price is higher than the previous high; it evaluates the relationship between opening prices, closing prices, and the extremes of the current candle. It uses these relationships to categorize "breakouts" or "breakdowns," providing a clearer picture of market intent.
4. Dynamic Drawing Logic The script manages how visual information is presented on your chart. It uses a state-based system (switching between upward and downward trends) to ensure that the markings remain clean and relevant. When certain conditions are met—such as a specific number of consecutive moves in one direction being reached—the script can automatically switch its focus, highlighting potential trend shifts or price reversals.
Summary for the User
In simple terms, this tool acts as an automated "trend mapper." It filters out the market noise to highlight significant structural highs and lows, while simultaneously keeping a tally of how many consecutive moves the market has made in a single direction. By identifying these key structural points and momentum counts, it helps traders see the broader "flow" of the market more clearly.
