A pattern name describes a shape in context. It is not a probability estimate or an entry instruction.
Shape needs context
The diagrams below are hypothetical sketches, not price data or signals. Small changes in a provider's definition can produce different pattern counts. Specify your rules before evaluating a pattern.
Ask what preceded it, where it sits relative to a broader range and whether liquidity or a scheduled release distorted the bar. Similar geometry can have different names after an advance or a decline.
Separate recognition from evidence
An engulfing pattern concerns the real bodies; it need not engulf both full high-low ranges. A doji has a very small body relative to its range, with the exact tolerance left to the chosen definition.
A later close beyond a pattern can be part of a predefined confirmation rule, but it can also worsen the entry price. Neither confirmation nor a recognised silhouette guarantees a reversal.
Test without seeing the future
Define the market, timeframe, prior trend, pattern tolerance and evaluation horizon. Include every matching case, costs and failures. Keep an untouched test period; selecting attractive screenshots after the event creates a misleading record.
