Crypto Volatility: Compression and Expansion
Volatility describes the size of market movement, not the direction of market movement.

How it is used in NotifyTrader
NotifyTrader uses ATR, ATR percentage, Bollinger bandwidth, and market state thresholds to describe Compression, Expansion, and Elevated risk.
Compression
Compression means price movement has become quieter. Bollinger bandwidth and ATR percentage are low, and directional strength is usually limited.
Compression can precede expansion, but it does not predict direction.
Expansion
Expansion means volatility is increasing. Bands widen, ATR rises, or price begins moving more aggressively.
Expansion can be useful for alerting because the market is changing from quiet to active.
How NotifyTrader uses volatility
Volatility is central to market state, risk labels, alert receipts, and assistant explanations.
The assistant should distinguish volatility from trend direction.
Questions to ask the assistant

FAQ
Does high volatility mean bearish?

Compression can show a quiet market that may become more active later.
