Concealing Baby Swallow: Trend or Exhaustion?

A Concealing Baby Swallow is a four-candle formation that appears only after a down-move and is said to mark the point where selling pressure may be spent.

What the pattern is

It consists of four consecutive candles. The first two are black marubozus—full-bodied candles that print without upper or lower shadows. The third candle opens inside the body of the second, trades lower, then recovers to close higher than its own open. The fourth candle is another black candle that completely engulfs the third.

What forms it

The sequence begins with two sessions of uninterrupted selling, each closing at its low. On the third day, price dips further yet buyers step in and push the close back above the open, leaving a small white candle inside the prior range. The fourth session opens lower still, then sweeps down far enough to cover the entire third candle before finishing lower.

What confirms it

Traders look for the strict absence of wicks on the first two candles, an intraday recovery on the third, and a fourth candle whose body fully contains the third. Any deviation from these three conditions removes the pattern from consideration.

How it fails

Because the setup is defined so narrowly, most four-candle strings that look similar do not qualify. If the first or second candle carries even a small wick, if the third fails to close above its open, or if the fourth does not engulf the third completely, the formation is disregarded.
