Just like a wedge, a rectangle is a forex chart pattern indicating a pause in the current trend. However, what differs is that rectangles signal continuation while wedges can lead to either continuation or reversal.
A rectangle is a pattern formed when the price is bounded by parallel support and resistance lines. Yeah, the two boundary lines must be parallel ones. Let us look at the chart below, the two yellow parallel lines and the price moving between them is what forex traders refer to as a rectangle pattern. The pattern in the chart is classified as a bearish rectangle on which I am going to focus.

To confirm a bearish rectangle, there are three basic points that we need to bear in mind. First, a bearish rectangle occurs following a downtrend. Second, there must be at least four pivot points-two on the support line and two on the resistance line. Third, after the rectangle pattern occurs, the price is going to breakout the support line and keeps moving downwards. That is to say: the downtrend resumes.

Here is one tip: if you are wondering when to enter the forex market, do not take any action until the support line is broken out by a strong candle. A strong candle means that the candle has a relative long body and has no or small shadows. Meantime, only when the line is broken by the body may you make a go, otherwise please stay patient.
It seems that a rectangle is much like a flag, right? Yeah, it may be. But there is one difference is that only when the pattern is less than three weeks can it be considered as a flag; ideally, a rectangle will develop a 3-month period.
Got it? I really hope that my analysis is going to help you make a better entry in your forex trading!
