Curved Radius Supertrend

The Curved Radius Supertrend indicator provides an adaptive parabolic trend framework that replaces traditional linear ATR bands with dynamic, radius-based curvature geometry. By integrating controlled acceleration, it allows the trend bands to fluidly adapt to both the velocity and duration of price movement, capturing the momentum curve of price action rather than just its direction.

Usage

The Curved Radius Supertrend can be used to identify sustained directional phases and early trend rotations while filtering out market noise.

• Trend Identification: A 'BUY' signal and green band indicate a bullish phase, while a 'SELL' signal and red band indicate a bearish phase.
• Momentum Analysis: The steepness of the curve reflects market conviction. A steepening curve suggests accelerating momentum, whereas a flattening curve may indicate potential exhaustion or consolidation.
• Trailing Stops: The curved band functions as a dynamic support or resistance level, making it suitable for volatility-adjusted trailing stops that tighten or widen based on market rhythm.
• Strategy Integration: Traders can use the indicator to time entries on pullbacks to the curved band or combine it with volume tools to confirm high-momentum breakout conditions.

Details

Unlike standard Supertrend algorithms that extend linearly from Average True Range (ATR) envelopes, the Curved Radius Supertrend models nonlinear market behavior. It uses a radius-based acceleration engine where each new bar compounds velocity, bending the trend line into a parabolic arc. This structural design aims to anticipate momentum transitions, eliminating the "stutter" effect of traditional systems and replacing it with a fluid directional motion that mirrors market inertia.

Settings

Supertrend Settings

• ATR Length: The number of bars used for the ATR calculation. Higher values produce smoother results, while lower values increase responsiveness.
• ATR Multiplier: Controls the distance of the initial bands from the price. Higher values result in wider bands and fewer signals.

Curve Settings

• Radius Strength: Determines the strength of the curve acceleration. Lower values create tighter, more reactive curves; higher values create wider, sweeping arcs.
• Smoothness: The period of the Simple Moving Average (SMA) applied to the curved band to reduce visual noise.

Color Settings

• Up Trend: Customizes the color for the uptrend band and associated buy signals.
• Down Trend: Customizes the color for the downtrend band and associated sell signals.

FAQ

How do I use the Radius Strength setting?

The Radius Strength should be adjusted based on your timeframe. For scalping (1-5m), lower values (0.002-0.005) are generally preferred, while higher values (0.01-0.03) are better suited for daily or weekly macro cycles to maintain smooth trends.

Can I use this for automated trading?

Yes, the indicator includes built-in alert conditions for trend flips (Buy/Sell signals) which can be used to trigger external automation or backtesting tools.
