- Parameterized by `period` (default defaultperiod), `multiplier` (default defaultmultiplier).
- Output range: Tracks input.
- Requires `period` bars of warmup before first valid output (IsHot = true).
- **Similar:** [BBands](../bbands/bbands.md), [KChannel](../kchannel/kchannel.md) | **Complementary:** Volume for breakout validation | **Trading note:** Stoller bands use ATR multiplier instead of standard deviation.
- Validated against TA-Lib, Skender, and Tulip reference implementations where available.
Super Trend Bands provide ATR-based dynamic support and resistance levels with asymmetric ratchet logic: the upper band only tightens downward during downtrends, and the lower band only tightens upward during uptrends. This creates natural trailing stop-loss levels that respect market momentum. A trend direction signal ($+1$ or $-1$) flips when price breaches the opposite band. The ATR is computed as a simple moving average of True Range via a ring buffer with running sum, providing O(1) streaming updates.
