Bollinger Band Bars + Hull (MT4)

Bollinger Band Bars + Hull colors bars by their position vs the Bollinger Bands and adds a Hull Moving Average (HMA) trend filter. You get clear squeezes/breakouts, trend pullbacks to the mid‑band/HMA, and practical alerts — all in MetaTrader 4.

What it shows

• Bollinger Bands (middle + upper/lower at STD multiples) and bar coloring for outside/inside/near‑band states.
• Hull MA filter to read trend/bias and smooth noise.
• (Optional) arrows/alerts — band breaks/touches, squeeze exit, mid‑band/HMA crosses and slope flips.

Trade ideas

1. Squeeze → breakout: wait for band contraction, then trade the first close outside with HMA in agreement.
2. Trend pullback: in an uptrend, buy pullbacks to the mid‑band or HMA with a hook‑up bar; mirror for shorts.
3. Mean‑reversion: if bands are flat, fade exhausted outer‑band tags back to the middle.
4. (Optional) Bar‑state sequencing: after an outside bar, use the first inside→outside in same direction to re‑enter.

Inputs that matter

• Band period / deviation — envelope width.
• HMA period — trend filter responsiveness.
• Price source — close/typical/median.
• Alerts — band breaks, mid/HMA crosses, squeezes.
• Colors/widths — fast visual read.

Suggested usage

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