# SVE Bands SVE Bands centers a volatility envelope on double-smoothed typical price (8-bar exponential pass then a second average) and offsets it by an EMA of a range-flavored deviation measure times 3.55, the lower band pulled to 0.9 of the upper offset. Slope-colored centerline, gradient fills and excursion/reversion alerts target calmer mean-reversion reads. - Indicator in the LuxAlgo Library, by LuxAlgo, published Feb 22, 2026. - Access: free. - Concepts: [SVE Bands](https://www.luxalgo.com/library/concept/sve-bands/) (primary) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=crue5ba8yil5vl1v81fpybli - Page: https://www.luxalgo.com/library/indicator/sve-bands/ **SVE Bands** builds Sylvain Vervoort's [SVE bands](https://www.luxalgo.com/library/concept/sve-bands/), an envelope that denoises its input before any band math runs. Typical price (optionally rebuilt from Heikin-Ashi-style averaged candles) is exponentially smoothed and averaged again, and the bands offset the double-smoothed base by an exponentially averaged, range-flavored deviation measure, so a single erratic bar barely deflects the pair. ## How to Trade the SVE Bands? - **Close beyond a band**: a stretch past the smoothed envelope. Fewer print than raw-band tags, each meaning more. - **Close back inside a band**: the calmer mean-reversion trigger this construction is built for, aiming back at the centerline as its natural target. - **Centerline slope**: the line tints with its direction, a low-flicker bias read, since the heavily smoothed center rounds through turns instead of jittering. Band Width plots to the data window: narrowing marks compression, widening release. Alerts cover excursions, reversions, centerline crosses and slope turns, a natural fit beside the rest of the [volatility toolkit](https://www.luxalgo.com/library/family/volatility/). ## SVE Bands Settings - **Input Series** (default Typical Price): raw typical price, or Heikin-Ashi Typical to blend each candle with its neighbors first. - **Smoothing Length** (default 8): length of the exponential smoothing and of the second average run on it. The double pass is the signature. - **Volatility Length** (default 13): lookback of the average on the deviation measure. - **Deviation Multiplier** (default 3.55): averaged deviation units the upper band sits above center. - **Lower Band Adjust** (default 0.9): fraction of the upper offset used below; set 1 for symmetry. - Style toggles cover slope coloring (on), the band gradient fill (on) and reversion markers (off). ## Frequently Asked Questions ### How do SVE Bands differ from Bollinger Bands? [Bollinger Bands](https://www.luxalgo.com/library/indicator/bollinger-bands/) wrap a raw moving average in standard deviations, so one wide-range bar deflects both center and width at once. SVE Bands smooth the input twice before centering and derive width from a range-based measure, trading immediacy for touches that filter one-bar spikes. ### Why is the multiplier 3.55 instead of 2? Because the offset is not a standard deviation. The measure compares typical price against neighboring lows across adjacent bars (a range gauge on a different scale), and the published 3.55 places the rails where genuine stretches, not routine noise, reach them. ### What is the cost of all this smoothing? Lag. Band excursions, re-entries and slope turns all land later than their raw-band equivalents, the deliberate trade for signals less prone to one-bar head fakes. Judge the balance on your own timeframe. ## Related indicators - [Hot Zone Radar](https://www.luxalgo.com/library/indicator/hot-zone-radar/) (Volatility Percentile/rank): markdown at https://www.luxalgo.com/library/indicator/hot-zone-radar.md - [Volatility Signature Plot](https://www.luxalgo.com/library/indicator/volatility-signature-plot/) (Volatility): markdown at https://www.luxalgo.com/library/indicator/volatility-signature-plot.md - [The Range Indicator](https://www.luxalgo.com/library/indicator/the-range-indicator/) (Volatility): markdown at https://www.luxalgo.com/library/indicator/the-range-indicator.md - [Jump Detection](https://www.luxalgo.com/library/indicator/jump-detection/) (Volatility): markdown at https://www.luxalgo.com/library/indicator/jump-detection.md - [Volatility of Volatility](https://www.luxalgo.com/library/indicator/volatility-of-volatility/) (Volatility): markdown at https://www.luxalgo.com/library/indicator/volatility-of-volatility.md - [Garman-Klass–Yang-Zhang Hybrid](https://www.luxalgo.com/library/indicator/garman-klass-yang-zhang-hybrid/) (Volatility): markdown at https://www.luxalgo.com/library/indicator/garman-klass-yang-zhang-hybrid.md - [GARCH-family Clustering](https://www.luxalgo.com/library/indicator/garch-family-clustering/) (Volatility): markdown at https://www.luxalgo.com/library/indicator/garch-family-clustering.md - [Kase Studies](https://www.luxalgo.com/library/indicator/kase-studies/) (Volatility): markdown at https://www.luxalgo.com/library/indicator/kase-studies.md --- Source: https://www.luxalgo.com/library/indicator/sve-bands/ (LuxAlgo Library).
