How to read a Parabolic Extension
A parabolic extension is a move that keeps getting steeper. Each candle is bigger than the last, pullbacks disappear, and price pulls far away from its averages. It's exciting to watch and hard to trade, because the move that looks unsustainable can keep going longer than seems possible.
What it looks like
The angle of the move bends upward. Early candles are normal, then they get wider, closes start landing near the highs, and price runs further and further above VWAP and the moving averages. Volume usually climbs into the top.
This isn't a pattern you enter so much as one you recognize. It tells you the move is late, not where it ends.
How traders read it
If you're already long, a parabolic run is a time to take profits into strength and tighten your stop, not to add size. Chasing a new long here means buying from people who got in much lower.
Short sellers look for the first sign the move has broken: a big red candle, a lower high, or a break of the last higher low. Shorting while it's still going up is guessing at the top, and the ones who guess early often get squeezed.
When it fails
For shorts, the danger is that a parabolic stock can go up another 20 or 50 percent after it already looks extended, especially a low-float name with a news catalyst. For longs, the danger is the reverse. When these break, they often drop fast, and a stop placed far below can fill much worse than planned.
After the top, many parabolic stocks bounce once or twice before fading. Those bounces can form bear flags or a head and shoulders.
Practice it
Replay an example above and pause it during the steepest part. Decide what you'd do if you were long and what you'd need to see before shorting. Then let it run and compare.
