Recognize a rectangle range and understand that the breakout direction is what matters.
Price stuck between two horizontal lines
A rectangle is the simplest pattern in technical analysis. Two horizontal lines. Support below, resistance above. Price bounces between them for some number of candles. That is the whole shape. There are no diagonals to draw and no convergence to argue about. Either you can see two clean parallel horizontal levels or you cannot. The rectangle is what consolidation looks like when neither buyers nor sellers can take control.
The pattern has no directional bias on its own. The shape is symmetric. Both boundaries get tested. Both boundaries hold. The only thing that matters is which side breaks. A close above resistance is a bullish trigger. A close below support is a bearish trigger. Until one of those events happens, you are inside the range and there is no signal to act on. Patient traders treat the boundaries as places to set alerts, not places to anticipate the breakout direction.
Rectangles often appear inside larger trends. A strong uptrend pauses, price chops sideways inside a rectangle for some candles, then the trend resumes upward through resistance. Same thing happens in downtrends. The trend leading into the rectangle gives you the most useful lean about how the breakout might resolve. A rectangle inside a daily uptrend has a continuation lean to the upside, even though the shape itself is neutral.
One quietly useful observation about rectangles. The longer the range, the more energy is stored inside. A rectangle that has been forming for fifty candles tends to produce a bigger move on resolution than one that has been forming for ten candles. This is not a hard rule. It is a tendency. The reason is mechanical. More candles inside the range means more stop orders accumulated near the boundaries. When one boundary finally breaks, those stops fuel the move.
Recap: rectangle is two parallel horizontal lines with price oscillating between. Neutral shape. Breakout direction is the signal. Trend leading in gives the lean. Longer ranges tend to produce bigger breakouts. False breaks are common, so wait for a decisive close rather than a single candle wick poking through one of the boundaries.
Knowledge check
Answer before moving on.
1. What is the directional bias of a rectangle pattern from its shape alone?
2. A single candle pokes above the resistance line of a rectangle and immediately closes back inside. What is the right read?
3. All else equal, which rectangle is likely to produce a larger move on breakout?
