Calculate regression channels with Fibonacci levels across multiple regression types, timeframes, and custom date ranges—with dynamic channel rendering and infinite projection.
Regression channels fit a statistical line through price data and project standard deviation bands around it. This indicator provides 8 regression calculation methods with 9 Fibonacci levels inside the channel, allowing you to analyze mean reversion zones, trend strength, and potential reversal areas across any lookback period or timeframe.
Features
8 Regression Calculation Types
- Linear: Classic least-squares linear regression
- Logarithmic: Natural log-based regression for exponential price moves
- Exponential: Exponential curve fitting for accelerating trends
- Weighted: Linear regression with recent bars weighted more heavily
- Polynomial: Curved fits (degree 1-5) for non-linear trends
- Moving: Moving average-based regression
- Exponential Moving: EMA-based regression for trend smoothing
- LOWESS: Locally weighted regression for adaptive smoothing
9 Fibonacci Channel Levels
- Full channel range: 100% (upper), 88.6%, 76.4%, 61.8%, 50% (midline), 38.2%, 23.6%, 11.4%, 0% (lower)
- Mean reversion zones within regression bands
- Precise support/resistance reference points
- Independent color/style/thickness control for each level
Multi-Timeframe Analysis
- Calculate regression on higher timeframe, display on current chart
- 16 timeframes available (m1 to Monthly)
- Interpolated channel values for smooth rendering across chart bars
- Higher timeframe structure without switching charts
3 Calculation Modes
- Period-Based: Rolling window of N bars (default)
- Date Range: Custom start/end datetime for specific events or phases with Timezone-aware datetime parsing (UTC+/- offset)
Channel Display Options
- Standard Output: Plot all 9 levels as indicator lines
- Extend to Infinity: Render as trendlines that project forward indefinitely
- Automatic refresh when colors/styles change
- Clean rendering—no residual values beyond calculation window
Date Range Mode
- Define exact start/end dates (dd/MM/yyyy HH:mm format)
- Analyze specific market events, phases, or structure
- Independent of period parameter
- Timezone conversion from user local time to server time
Dynamic Calculation
- Real-time updates as new bars form
- Optimized LRU caching for performance
- Adaptive cache sizing based on timeframe
- Handles multi-timeframe data efficiently
Channel Width Control
- Standard deviation multiplier (default 2.0)
- Wider bands for volatility expansion
- Tighter bands for range-bound markets
- Consistent across all regression types
Polynomial Regression
- Degree control: 1-5 (higher = more curvature)
- Captures non-linear trends
- Useful for parabolic or curved price structures
- Falls back to linear when degree = 1
Clean Visual Management
- No calculation on forming bar—only completed bars
- Proper multi-timeframe truncation—lines end at last completed HTF bar
- Slope-based extrapolation for consistent directional projection
- Clear output series with descriptive level names
