Change of Character (CHoCH)

Change of character, usually shortened to CHoCH, is a price-action idea for spotting the first sign that a trend may be losing momentum. In an uptrend it is the first lower low; in a downtrend it is the first higher high.

It is meant to be an early warning, smaller and earlier than a full market structure shift (MSS), which some traders treat as a stronger confirmation that follows.

A stock has been in an uptrend, making higher lows at $100, $104 and $108. Then a pullback breaks below $108 and touches $106 before bouncing. That break of the most recent higher low, even a small one, is what some traders label a CHoCH.

It does not mean the uptrend is over. It means the pattern of higher lows just broke for the first time, which is worth watching.

Traders who use both terms usually treat CHoCH as the earlier, smaller warning and MSS as the bigger confirmation, often the break of a more significant swing point rather than the most recent minor one. Not everyone draws the line between them the same way, so definitions vary from trader to trader.

Because a CHoCH marks a small, recent swing point, it happens often and many of them are false alarms: the original trend resumes right after. It is meant to raise attention, not to be traded on its own.

As with other price-action ideas, there is no single agreed-upon rule for identifying one, and this page describes a way traders read charts, not a signal.
