Dante Bullish/Bearish Engulfing

Bearish and Bullish engulfings as taught by Tom Dante Piccin. Different from other bullish/bearish engulfing indicators because other indicators only want the body of the current candle to engulf the previous body.
This indicator needs the low and high of the current candle to engulf the previous one and also in the example of a bullish engulfing close above the previous candle high or in a bearish engulfing example close below the low of the previous candle.
