Crypto Chart Patterns: Definitions, Confirmation and Bias
Chart patterns describe price geometry. To evaluate one, define its pivots, completion time, invalidation and costs before measuring outcomes.
Key Takeaways
- Define geometry and tolerances before testing.
- Use the actual time a pivot becomes known.
- A projection target is not an expected or guaranteed outcome.
- Preserve failed candidates and evaluate filters independently.
Make the Pattern Reproducible
Specify how a swing high or low is identified, the allowed distance between points and the tolerance for similar levels. A pivot requiring later bars is only known after those bars arrive. Drawing a confirmed pivot on an earlier candle must not imply it was actionable then.
Define Reversal Candidates
A head-and-shoulders candidate has three peaks with a higher middle peak and intervening troughs used for a neckline. A double top uses two comparable highs and an intervening trough; a double bottom reverses the geometry. Specify a touch, close or retest trigger. A completed shape does not establish that the preceding trend has ended.
Define Continuation Candidates
A flag commonly describes a consolidation channel after a directional move; a pennant uses converging boundaries. Wedges can occur in different trend contexts. A measured-move target is a projection rule, not a forecast that price will travel that exact distance. Record failed and incomplete candidates as well as recognizable winners.
Evaluate Filters Rather Than Declare Confirmation
Volume thresholds and RSI divergence can define additional conditions. There is no established universal 1.5-times-volume threshold, sub-50% failure boundary or twenty-percent win-rate uplift on this page. Compare the same pattern definition with and without each filter, including the effect on sample size and missed trades.
Test Across Time Without Future Information
Use a consistent venue and bar interval, include costs and preserve a later evaluation period. Pattern resemblance across intervals does not imply equal probabilities or higher reliability on longer charts. Pineify can help express a definition as code, but the source and detection timing still need review.

Frequently Asked Questions
Which pattern is most reliable?
No tested ranking is provided. Reliability depends on definition, sample, timing and outcome measure.
Does a neckline break prove reversal?
No. It can be the specified trigger, but price can reverse again or fail to continue.
Are measured-move targets guaranteed?
No. They are geometric projections used to define a hypothesis.
Why does pivot confirmation matter?
Some pivots require future bars to confirm the earlier high or low. Testing an entry before confirmation introduces lookahead bias.
