OPEN-SOURCE SCRIPT
Volatility Squeeze & Momentum
This indicator flags low-volatility "squeeze" phases and pairs them with a momentum histogram, so that volatility expansions can be read together with direction. The squeeze concept was popularized by John Carter (TTM Squeeze); this script is an original open-source implementation of that public idea.
How it works
A squeeze is on when both Bollinger Bands (default 20, 2.0) sit inside the Keltner Channels (default 20, 1.5 x average true range) — a sign that recent volatility is unusually compressed. The zero line shows the state: orange dots while the squeeze is on, gray otherwise. Momentum is a linear-regression estimate of price relative to a midline (average of the Donchian midpoint and the SMA), shown as a four-color histogram: rising/falling shades above and below zero.
Three alert conditions are included: squeeze release, release with positive momentum, and release with negative momentum.
Notes and limitations
A squeeze marks compression, not direction — releases can resolve either way, and momentum at the moment of release is context, not a guarantee. All parameters are configurable; defaults follow common usage.
