What is Change of Character (CHoCH)?

The first structural break against the trend — the earliest chart evidence that a reversal may be starting.

A Change of Character (CHoCH) is the first break of structure against the prevailing trend. In an uptrend, price is supposed to keep printing higher highs and higher lows; when it instead breaks below the most recent higher low, the character of the market has changed — buyers failed to defend the level that defined their control. It is the mirror of a BOS: a BOS confirms continuation, a CHoCH warns of possible reversal.

A CHoCH is early evidence, not a finished reversal, and treating it as an instant entry signal is a common way to get caught in a deep pullback. Professionals strengthen the signal with context: a CHoCH that follows a liquidity sweep of a major high or low, breaks the swing with displacement, and happens at a higher-timeframe zone of interest is far more reliable than one printed in the middle of nowhere. After a valid CHoCH, the usual plan is to wait for the retracement into the origin of the move and enter there with defined risk.
