Volatility Squeeze – Blue Zone (classic)

Volatility Squeeze – Blue Zone

Highlights periods when volatility contracts by showing a blue band between the Bollinger Bands (BB) whenever they fall inside the Keltner Channel (KC).

Blue zone = squeeze: BB upper & lower are inside KC – market coiling.

Automatic breakout alert: optional alert fires on the first bar after the squeeze releases.

Fully adjustable: BB/KC length, BB σ, KC ATR multiplier, zone colour & opacity, border on/off.

Clean overlay: zone hugs price bar-by-bar and disappears only when the squeeze ends, so past squeezes remain visible for context.

Use it to spot low-volatility setups, then watch for momentum or volume confirmations when the squeeze breaks.
