Curvature Trend Description
Purpose: Identifies the direction, strength, and potential reversal points of a trend.
Key Features:
- A primary trend band that adapts to market conditions.
- Adjustment based on “curvature” (similar to a radius) that modifies the band’s angle according to volatility and price movement.
- Upper and lower bands acting as dynamic support/resistance levels.
- Adjustable parameters such as initial distance and volatility multiplier.
Since ProRealCode does not have a native “curvature” function like some TradingView indicators, we approximate it using a combination of moving averages, volatility (such as ATR), and dynamic adjustments to replicate the described behavior.
Parameters:
- StartDistance: Initial multiplier to define the band width (equivalent to “Start Points Distance” in Radius Trend).
- StepCurvature: Incremental curvature adjustment to simulate the dynamic angle change (based on volatility).
- ATRPeriod: ATR period to measure market volatility.
- TrendLength: Length of the moving average that serves as the trend base.
Core Components:
Primary Trend (TrendBase):
An EMA (Exponential Moving Average) is used as the central line, similar to how the Radius Trend establishes a dynamic base.
Volatility (Volatility):
ATR (Average True Range) is used to adjust the bands according to volatility, mimicking the adaptability of the original indicator.
Dynamic Bands:
- UpperBand and LowerBand are calculated by adding/subtracting a multiple of volatility to/from the trend base.
- The curvature adjustment is simulated by incrementing or decrementing the bands based on price direction (PriceChange), imitating the adaptive behavior of the Radius Trend.
Output:
Returns three lines: the upper band, the primary trend (curvature), and the lower band, which can be visualized on the chart.
