Download script
This tool is designed to provide a visual representation of market trends by highlighting specific price action on your trading chart. Instead of standard candles, it uses a dual-colored histogram system to help traders identify the prevailing momentum between "Up" and "Down" movements.
Core Logic Overview
The script analyzes historical price data over a user-defined period to determine whether the current market sentiment is bullish or bearish. It does this by calculating the highest and lowest price points within a specific window of time (the "Period"). By establishing these boundaries, the tool can measure where the current closing price sits relative to that recent range.
How it Identifies Trends
The logic operates based on a "buffer" or "threshold" system:
- Trend Detection: The script looks at the distance between the highest high and the lowest low of the selected period.
- Dynamic Coloring:
- If the price closes significantly toward the lower end of that range (based on a percentage you can set), the tool marks the bars to reflect a downward bias.
- Conversely, if the price closes significantly toward the upper end of that range, it marks the bars to reflect an upward bias.
- Visual Output: These findings are rendered as histograms directly on your chart. The colors (typically Blue and Red) shift automatically as the price action moves between these high and low extremes, providing a clear visual cue of the current trend direction.
Key Features for the User
- Customizable Sensitivity: You can adjust the "Period" to change how much historical data the tool considers when deciding on a trend, and the "Offset" (Otstup) allows you to control how sensitive the color changes are to price fluctuations.
- Data Management: The script includes an optimization feature that ensures it only calculates data for the amount of history you actually want to see. This keeps the chart running smoothly without unnecessary processing of ancient data.
- Clean Integration: It is designed to sit on the main chart window, providing a clean visual overlay that simplifies the interpretation of market structure at a glance.
