SVE Bands

SVE Bands builds Sylvain Vervoort's 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.

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 its anchor, an exponential second pass of the smoothed price (the plotted centerline is a simple average of the same series).
• 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).
