A bar makes a new extreme, then closes back the other way.
What it looks like
A bar that makes a new extreme then closes back inside the prior range — signals a potential swing turn.
Works best with trend and volume context.

How to identify it
- In a rise, find a bar that makes a new high (in a fall, a new low).
- Check that the same bar closes back past the previous close.
- Next bars that move away from the extreme support the read.
When the read is wrong
Invalid if price moves back beyond the key bar's extreme.
Common mistakes
- Treating one bar as a change of trend. It marks a possible swing turn, not a new trend.
- Using a timeframe too low to matter, where these bars appear constantly.
Questions and answers
What is a key reversal bar?
A bar that pushes to a new high or low in the trend, then closes back against that move.
Is a key reversal the same as an engulfing candle?
Not exactly. A key reversal is about a new extreme and the close against it. An engulfing candle is about one body covering another. One bar can be both.
