Engulfing reversal needs trend and a trailing stop

How an engulfing pair is identified

An engulfing-pair is two consecutive candle bodies of opposite color in which the later body fully covers the earlier body. Shadows are not part of the identification rule.

Candle bodies encode open-close direction by appearing dark when the close is below the open and light when the close is above the open. Volume, moving averages, and oscillators may confirm a wrap but are not required to identify it.

Trend context and confirmation

A reversal reading requires a prior trend. After a decline the pair is a dark body then a light body. After an advance the pair is a light body then a dark body.

Trend-context is a run of higher highs or lower lows that locates the pair as a reversal attempt rather than a continuation print. An uptrend is a succession of higher highs and a downtrend is a succession of lower lows, often read from closes.

A body-size-filter treats a second body more than 30 percent larger than the first as a stronger engulfing condition. Third-day-confirmation is a close on the session after the pair that continues in the reversal direction.

After three failed reversal attempts the structure is treated as a consolidation-range that may resume the prior direction.

The equity case and written stops

In the 15-month equity case from May 2000 into mid-2001, planned entries were the next session near the open with rounded prices.

A late-June 2000 buy-side pair was skipped because it appeared in an advance or continuation rather than a decline, and nine-day and 18-day exponential averages did not support that pair.

A pattern-only pass without a trend filter produced trades inside sideways ranges, which motivated an explicit stop-loss, a five-dollar trailing-stop, and a five-day minimum gap between trades.

Editorial reading: that workflow treats the wrap as incomplete until the prior higher-high or lower-low sequence is named and a stop is written before the next open. A stop-loss is a precommitted exit that bounds the loss if the wrap fails as a reversal. A trailing-stop follows price by a fixed distance so an open position stays bounded after entry.
