Curvature Trend

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.
