Miha Kralj fdfbfd98f0 Add Starchannel indicator implementation and validation tests
- Implemented the Starchannel class, which calculates a volatility-based envelope using SMA as the middle line and ATR for band width.
- Added methods for updating the indicator with new data, batch calculations, and state management.
- Created comprehensive unit tests for the Starchannel indicator, validating various scenarios including manual calculations, consistency across modes, eventing, and handling of large datasets.
- Ensured that the indicator's outputs are finite and that band widths are consistent across different calculation modes.

Channels

"In trending markets, ride the channel. In ranging markets, fade the edges." Unknown

Channels define dynamic support and resistance. Upper band shows where price tends to find resistance; lower band shows support. Width measures volatility; price position within channel measures momentum and mean-reversion potential.

Indicators

Indicator Full Name Description
ABBER Aberration Bands Absolute deviation-based volatility bands. More robust than standard deviation.
ACCBANDS Acceleration Bands Volatility-based adaptive channel by Price Headley. Width adapts to momentum.
APCHANNEL Andrews' Pitchfork Three-line channel based on pivot points. Projects trend support/resistance.
APZ Adaptive Price Zone Double-smoothed EMA volatility channel by Lee Leibfarth. Adapts to recent volatility.
ATRBANDS ATR Bands ATR-based volatility bands around moving average.
BBANDS Bollinger Bands Standard deviation bands around SMA. Classic volatility channel.
DCHANNEL Donchian Channels Highest high and lowest low over N periods. Turtle trading foundation.
DECAYCHANNEL Decay Min-Max Channel Exponentially decaying min-max channel. Half-life decay toward midpoint.
FCB Fractal Chaos Bands Tracks fractal highs and lows. Identifies chaos-based support/resistance.
JBANDS Jurik Adaptive Envelope Bands JMA's internal adaptive envelopes. Snap to extremes, decay toward price.
KCHANNEL Keltner Channel EMA with ATR bands. Smoother than Bollinger.
MAENV Moving Average Envelope Fixed percentage bands around moving average. Simple but effective.
MMCHANNEL Min-Max Channel Rolling highest high / lowest low using O(1) monotonic deques.
PCHANNEL Price Channel Highest high and lowest low. Identical to Donchian Channels.
REGCHANNEL Linear Regression Channel Linear regression line with standard deviation bands.
SDCHANNEL Standard Deviation Channel Moving average with standard deviation bands.
STARCHANNEL Stoller Average Range Channel SMA with ATR bands. Similar to Keltner but uses SMA instead of EMA.
STBANDS Super Trend Bands ATR-based trend-following bands. Flips direction on breakout.
UBANDS Ultimate Bands Composite volatility bands using multiple measures.
UCHANNEL Ultimate Channel Adaptive channel using multiple volatility inputs.
VWAPBANDS VWAP Bands Volatility bands around VWAP. Institutional trading reference.
VWAPSD VWAP Standard Deviation Bands Standard deviation bands around VWAP.
