Candlestick patterns: context, confirmation, and failure

Candlesticks compress open, high, low, and close into a visual record of one interval. They do not show the exact path between those prices, who traded, or which side initiated each transaction. Start with that limitation before naming a pattern.

Read the candle before the label

The body spans the open and close. Wicks show the remaining extremes. A large body says the close is far from the open relative to that candle; it does not tell you whether the move is unusually large for the instrument. Compare it with recent ranges and the surrounding structure.

A doji has a small body relative to its range. A hammer-like candle has a relatively small body near the upper end and a longer lower wick. An engulfing pattern compares adjacent bodies. Different platforms use different tolerances for these definitions, so specify your own rule before measuring outcomes.

A rejection needs a location

Imagine a hypothetical candle opening at 100, trading down to 96, and closing at 101 near a previously identified support area. It records a recovery during that interval. It does not prove a durable bottom. The next candle could immediately trade through 96.

A testable setup might require a completed rejection candle, a later break of its high, and invalidation below the rejection area. Another system might enter at the next open. Those are different strategies with different fill assumptions; neither follows automatically from calling the candle a hammer.

Confirmation has a cost

Waiting for another candle can filter some failed attempts, but it also changes the entry and stop distance. If a long entry rises from 101 to 104 while the structural invalidation stays at 96, the planned risk per unit increases from 5 to 8 before costs. A later signal can be clearer and less attractive at the same time.

Check the available reward to the next resistance area instead of assuming that extra confirmation always improves the trade.

Common mistakes to record in a journal

• Naming a pattern before the candle closes, then forgetting it changed.
• Comparing candles from feeds with different session boundaries.
• Counting every overlapping pattern as an independent observation.
• Assuming the stop or target happened first when both lie inside one historical candle.

Resolve ambiguous intrabar sequences conservatively or use suitable lower-resolution data. Do not select the favorable order after inspecting the result.
