Wedgies: a tiring trend
A wedge is a structure where two lines slope in the same direction but converge. A rising wedge indicates a tiring uptrend, and a falling wedge indicates a tiring downtrend.
In the chart above, you see two lines sloping in the same direction but converging: ‘UPPER’ and ‘LOWER’. The difference from a triangle is that both lines move in the same direction. In a rising wedge, both lines slope upwards, and in a falling wedge, both lines slope downwards. The color indicates the classic tendency of the structure: a rising wedge is drawn red (bearish tendency), and a falling wedge is drawn green (bullish tendency).
These colors might seem counterintuitive at first glance: why is a rising structure red? Because in a wedge, the important thing is not the direction, but the narrowing. In a rising wedge, the price is still rising, but each new high rises less than the previous one, while the lows rise faster. The steps of the uptrend are shortening; buyers are getting tired. This fatigue can eventually result in a break below the lower line. A falling wedge is the other side of the coin: the price is falling, but each new low is less deep than the previous one. The sellers' power is diminishing.
What distinguishes a wedge from a channel is that the lines are not parallel. In a rising channel, highs and lows rise at the same rate; the trend is healthy. In a wedge, however, the lines converge, and this narrowing indicates that the energy of the movement is being depleted.
Some wedges expand in reverse: the lines go in the same direction but move away from each other. This expanding wedge is a more indecisive and volatile structure.
The meaning of the wedge also emerges with a breakout. If a rising wedge breaks with a close below its lower line, the uptrend fatigue may have turned into a real reversal. But the wedge can also break upwards; in that case, the fatigue reading was wrong, and the trend is accelerating.
How to read it
- Check that the two lines are sloping in the same direction and converging; if they are parallel, it's a channel.
- Compare the step sizes of the highs and lows: in a rising wedge, highs rise less and less.
- Wait for the breakout with a close; do not make a direction prediction while inside the wedge.
- Place the stop beyond the last high or low opposite to the breakout.
Trap
The most common mistake is to see a rising wedge and short sell in the middle of a strong uptrend. The wedge can continue to rise for a long time, and the fatigue reading only makes sense when the lower line is broken. The second trap is to mistake the color for direction: a red line does not mean 'it is currently falling', it means 'this structure is classically considered bearish'. Look at the candles to see what the price is actually doing.
Tip
Wedge and RSI divergence often appear together: if the price makes a new high in a rising wedge while the RSI makes a lower high, two different pieces of evidence indicate the same fatigue. You can look for both together on the evidence card.
Glossary
- Rising wedge
- A structure where both lines slope upwards but converge; it indicates a tiring uptrend, classically bearish.
- Falling wedge
- A structure where both lines slope downwards but converge; it indicates a tiring downtrend, classically bullish.
- Narrowing
- The distance between highs and lows gradually decreasing.
- Expanding wedge
- A volatile and indecisive structure where its lines go in the same direction but move away from each other.
