T3 TRIX (ROC of T6)
Download script
This script is a specialized technical analysis tool designed to measure momentum and price velocity within the MetaTrader platform. It focuses on analyzing price movements by applying several layers of mathematical smoothing to identify underlying trends while filtering out minor "market noise."
Core Logic Overview
The indicator operates by taking raw price data (either the Opening or Closing prices, depending on your settings) and passing it through a sophisticated multi-stage processing sequence. Instead of simply looking at how much a price moved from point A to point B, this script calculates the "Rate of Change" based on smoothed averages.
How the Data is Processed
- Smoothing Layers: The script utilizes two primary time periods (A and B). It creates a series of moving averages where each step depends on the previous one. By nesting these calculations (passing the result of one calculation into the next multiple times), the script achieves a very high degree of smoothness. This helps in visualizing the "true" direction of the market rather than erratic fluctuations.
- T3 Filtering: The logic employs a specific mathematical formula (the T3) to weight the data. This allows the indicator to react more intelligently to price turns while remaining stable, preventing the common "choppiness" found in standard moving averages.
- Rate of Change (ROC) Calculation: Rather than plotting the absolute price or a simple average, the script calculates the percentage difference between the current smoothed value and its previous value. This effectively turns the indicator into a velocity meter—showing you how fast the trend is accelerating or decelerating.
Visual Outputs
The script produces two distinct lines on a separate window below your main chart:
- Line 1 (Primary Trend): Represents the momentum of the first smoothed period. It shows the percentage change of the primary trend calculation.
- Line 2 (Composite/Secondary Trend): Depending on your settings, this line either represents the momentum of a second, shorter-term period or a combined "differential" sum of both trends.
Key User Controls
- Time Periods: You can adjust the sensitivity of the two primary smoothing layers.
- Price Source: You can choose whether the logic tracks the price at the start of a candle (Open) or the end of a candle (Close).
- Differential Mode: This allows you to toggle whether the second line behaves as an independent momentum tracker or a combined value of both trends.
In summary, this tool is designed for traders who want to see the "speed" of a trend. It strips away the volatility of the market to highlight the underlying strength and velocity of price movements.
