Incorrect ENGULFING ?

I am having troubles with my proscreener to detect engulfing patterns on a Daily chart (I did not test other TFs, so far).

ProScreener sometimes reports incorrect results.

This is my code:

ONCE BodySize = 10 * pipsize                                       //Body is required to be at least 10 pips large
Engulf  = 0                                                        //Variable used for criterion
Body    = abs(open - close)                                        //This is the BODY of the candle
Bearish = open > close                                             //BEARish candle
Bullish = open < close                                             //BULLish candle
IF Bearish[1] THEN                                                 //Previous candle was BEARish
   IF open <= close[1] AND close >= open[1] AND Bullish THEN       //  this candle's Open must be <= previous Close AND Close >= previous Open AND must be Bullish
      Engulf = (Body > Body[1]) AND (Body >= BodySize)             //  this candle's Body > than previous one AND >= desired size
   ENDIF
ELSIF Bullish[1] THEN                                              //Previous candle was BULLish
   IF open >= close[1] AND close <= open[1] AND Bearish THEN       //  this candle's Open must be >= previous Close AND Close <= previous Open AND must be Bearish
      Engulf = (Body > Body[1]) AND (Body >= BodySize)             //  this candle's Body > than previous one AND >= desired size
   ENDIF
ENDIF
SCREENER[Engulf]

I tried so many time to study my code, but can’t find any logic error. An engulfing pattern must have a greater body, no gaps (unless they are part of the engulfing itself) and going the other way round.

I attach a screensot of current Aud/Jpy daily chart.
