An engulfing pattern compares the bodies of two candles. A bullish version has an upward-closing second body covering the preceding downward-closing body; a bearish version reverses those directions. This is a price-shape definition, not a reliable reversal probability by itself.

Body and Full Range Are Different

The body spans open to close. Wicks extend to the high and low. Body engulfment does not require the second candle's full range to engulf the first, and requiring that range condition creates a different rule.

State whether equal opening or closing boundaries count. Strict inequalities may select few patterns in markets where successive bars commonly open at the previous close. Colour conventions are configurable, so compare the price values rather than assuming green and red always mean the same thing.

A larger second candle creates a larger body, not necessarily a stronger edge. It can also increase the distance between entry and a stop beyond the pattern.

An Illustrative Long Setup

Suppose the first candle opens at $50 and closes at $49. The next opens at $48.90 and closes at $50.20. Its body covers the first. If a rule enters only after the second close, the actual fill can differ from $50.20.

Define whether the stop reference is the second candle's low or the lowest point of both candles, then calculate quantity from that distance and an execution allowance. A protective order does not guarantee that one failed trade cannot exceed prior gains.

Test Context Instead of Assuming It Helps

A prior decline, support zone or volume filter can be specified as another condition. Compare the amended rule with the unfiltered one using the same exit method and costs. Several price-derived indicators are not independent votes.

Save the pattern before the result and include failures. A bearish engulfing after a rally need not mark the top, and a bullish engulfing in a range is still an observable shape even if your strategy excludes it. The candlestick guide explains what the underlying OHLC data can and cannot show.
