A rectangle pattern in technical analysis is a chart formation that occurs when the price of an asset moves sideways between two clearly defined horizontal levels of support and resistance. It represents a period of consolidation in which buyers and sellers are temporarily balanced, with neither side having enough strength to push the market decisively in one direction. The pattern typically develops after a strong upward or downward price movement and can signal that the existing trend may continue once consolidation ends.

The upper boundary of the rectangle acts as resistance, while the lower boundary provides support. Price often moves back and forth between these levels several times, creating a rectangular appearance on the chart. Traders generally watch for a decisive breakout above resistance or below support to determine the next potential direction. A breakout above resistance may signal bullish continuation, while a breakdown below support can indicate bearish continuation.

Volume can also provide useful confirmation. Trading activity may decline while the price remains inside the rectangle, reflecting reduced momentum during consolidation. A significant increase in volume during a breakout can strengthen the signal and suggest greater market participation.

To estimate a potential price target, traders often measure the vertical height of the rectangle and project that distance from the breakout point. However, false breakouts can occur, so traders may wait for a candle close beyond the boundary or a successful retest before entering a position. Overall, the rectangle pattern is useful for identifying consolidation, potential trend continuation, and important breakout levels.
