1310 - Important Engulfing lesson

I lost the above trade (I am on sell), which I had yesterday.
I was calling it a tumor.
I was in my office, re-reading about Engulfing price action.
I realized that the above did not conform with one rule.

The closing price has to be close to the lowest price of the candle.

But the above engulfing, even though the body is big, the tail is quite long.
