Change of Character (CHoCH)
C
Definition
An informal chart label for a local price move that conflicts with a trader's chosen swing sequence. It does not provide an early warning, identify institutional activity, or predict a higher-timeframe reversal.

Supports: CFTC explains that trading systems based on historical market data cannot guarantee profits, supporting the distinction between a local chart label and a verified trade outcome.

Key Takeaways
1
CHoCH is an informal local-pattern label whose timeframe, swings, and invalidation rule must be stated before measuring results.
2
A local break does not establish exhausted momentum, institutional intent, a supply or demand cause, or a higher-timeframe reversal.
3
Do not select swings after a move has worked; that hindsight makes a chart label appear more predictive than it was.
4
Evaluate a complete rule out of sample with execution costs and losses; CHoCH is not an early-entry instruction.
Practical Example
A researcher labels a five-minute close beyond a defined local swing as CHoCH and records every occurrence without changing the rule. They then compare the same decision rule against a non-CHoCH benchmark in later data, including fills and fees. A local move is recorded as an observation, not evidence that buyers, institutions, or a reversal have appeared.
