Bollinger Bands with 4 Moving Averages

Combines Bollinger Bands (BB) with up to four optional Moving Averages (MA) to read volatility, trend direction, and dynamic support–resistance in one overlay.

How It Works

BB: basis = MA(length, type) with standard deviation mult. upper = basis + dev, lower = basis − dev.

MA1–MA4: additional averages you can toggle (default only MA4/200 enabled).

Key Features

Flexible basis MA type for BB: SMA / EMA / RMA (Wilder) / WMA / VWMA.

Four optional MAs with independent length, color, and width (defaults: 7, 25, 99, 200; only 200 on by default).

Offset to shift BB for visual testing.

Overlay on price with shaded band between Upper–Lower.

Inputs & Defaults

BB Length = 20, StdDev = 2.0, Source = close.

Basis MA Type = SMA.

MA4 active (200), MA1–MA3 off (7/25/99 ready).

Offset = 0.

Practical Use

Use BB for volatility context: squeeze → potential breakout; expansion → strong trend.

Treat Basis / Upper / Lower as dynamic levels:

Pullbacks to Basis often become decision zones in trends.

Upper/Lower touches = relative extremes.

Add MA4(200) for primary bias; enable MA1–MA3 for finer timing.

Typical behavior:

Price > MA200 and rising basis → bullish bias; watch pullbacks to basis/MA25-like zones.

Price < MA200 and falling basis → bearish bias; watch rejections at basis/MAs.

Common Signals (not financial advice)

Breakout + BB expansion confirms momentum.

Squeeze + basis break can preface volatility expansion.

Confluence: Lower touch + fast MA in uptrends → mean-reversion setups; inverse for downtrends.

Notes

MA1–MA4 are SMA in the code; BB basis follows the selected MA type.

Test across timeframes; tune length and mult to the asset.
