A Rectangle Chart Pattern is a technical analysis pattern that is formed when the price of a security trades within a narrow range for an extended period of time. It is characterized by two horizontal lines that act as resistance and support levels, creating a box or rectangle on the chart.The pattern is usually formed after a significant price move, and it is often seen as a period of indecision or consolidation, as the bulls and the bears are in balance and the price is unable to break through either the resistance or support level. When the price eventually breaks out of the rectangle, it is often seen as a sign of a trend reversal or a continuation of the existing trend, depending on the direction of the breakout.
