EURUSD Piercing line or maybe engulfing...

Piercing line:
This is a two day pattern. A white day follows a long black day that gaps below the black day’s low and closes within and above the midpoint of the black day’s body.

Engulfing:
This is a two day pattern. A large white day “engulfs” the previous black day that gaps below the black day’s low and increases to close above its high.
