Sideways

Sideways describes a price that is neither rising nor falling in any sustained way, instead bouncing back and forth within a roughly stable range over some period of time. On a chart it looks flat overall, even though the price may still be jumping up and down from bar to bar.

This happens when buying pressure and selling pressure are roughly balanced. Every time the price nears the top of the range, enough sellers show up to push it back down; every time it nears the bottom, enough buyers step in to push it back up. The result is a horizontal band, often called a consolidation range, bounded by a rough ceiling (resistance) and floor (support), rather than a clear staircase up or down.

The nuance that trips people up is that sideways is a description of the bigger picture, not of any single candle or short move. A stock can have several sharp green and red bars in one hour and still be "sideways" if, zoomed out, it started and ended the day near the same price with no higher highs or lower lows building over time. Whether something counts as sideways also depends on the timeframe you're looking at: a stock can be sideways on a 5-minute chart while it's actually trending on a daily chart, or vice versa.

Sideways markets often end with a breakout, where the price finally pushes decisively through the top or bottom of the range, or they can persist for a long time, especially in low-volume or low-interest conditions, such as around holidays or ahead of a major scheduled announcement.
