SVE Bollinger Band (MT4)

SVE Bollinger Band enhances the classic Bollinger Bands with SVE smoothing/adaptivity. You get cleaner band rides and squeezes, earlier volatility shifts, and actionable alerts in MetaTrader 4.

What it shows

• Middle SVE average plus upper/lower bands at dynamic STD multiples.
• Squeeze/expansion states for breakout timing and mean‑reversion context.
• (Optional) arrows/alerts — band touches/breaks, squeeze exit, midline crosses and slope flips.

Trade ideas

1. Squeeze → breakout: wait for band contraction, then trade first close outside with follow‑through; use the midline as a bias check.
2. Trend pullback: in an uptrend, buy pullbacks to the middle SVE or to the lower band with a hook‑up; mirror for shorts.
3. Mean‑reversion: fade exhausted outer‑band tags back to the midline when bands are flat.
4. (Optional) Volatility trail: use the opposite band or adaptive ATR as a trailing stop.

Inputs that matter

• SVE length / smoothing — stability vs responsiveness.
• Band deviation — STD multiplier for the envelopes.
• Source price — close/typical/median.
• Alerts — band breaks, midline crosses, squeezes.
• Colors/widths — quick visual read.

Suggested usage

• M5–M15: squeeze breakouts and pullbacks.
• M30–H4: swing continuations; ride the band.
• Daily+: regime read and trailing stops.
