What it means
Price compression describes a narrowing pattern in market movement. Candles may become smaller, short-term pullbacks may reduce in size, or the distance between recent highs and lows may contract.
Compression may appear near support, resistance, inside a trading range or during a period of lower volatility.
It is sometimes associated with a developing breakout setup, but it does not establish which direction price will move or whether a breakout will occur.
Why it matters in live markets
Price compression helps describe a change in the rhythm of a market. Instead of moving through wide swings, price spends more time within a smaller area.
This can reflect temporary balance between buyers and sellers, reduced participation, caution before new information or repeated interaction with a chart boundary. The reason for compression depends on the wider market environment.
Key points
- Price compression means market movement is becoming more contained.
- It may appear through smaller candles or narrower short-term ranges.
- Compression often develops near a recognised support or resistance area.
- It can precede a breakout, continuation, reversal or continued range trading.
- Compression provides market context but does not predict direction.
Example
A market may repeatedly approach resistance while each pullback becomes smaller. The narrowing movement below the level may be described as price compression. Price could later move above the level, move lower or remain contained.
