This is an example of multiple signals https://www.prorealcode.com/topic/multi-timeframe-screener-needed/#post-85538

There you go:

// it will return two chatacters, one for each different screener, the rightmost for the first screener (engulfing
// patterns) and the leftmost for the second screener (crossings)
//
// For each one of the above two it will either return:
//        1  = long
//        2  = short
//
// So you may have these 8 combinations (9=zero, just to avoid it from being dropped):
//
//        91 = No crossing and Engulfing is Bullish
//        92 = No crossing and Engulfing is Bearish
//        10 = Crossover   and NO Engulfing
//        20 = CrossUnder  and NO Engulfing
//        11 = CrossOver   and Bullish Engulfing
//        12 = CrossOver   and Bearish Engulfing
//        21 = CrossUnder  and Bullish Engulfing
//        22 = CrossUnder  and Bearish Engulfing
//
Bullish          = close > open
Bearish          = close < open
Body             = abs(open - close)
BullishEngulfing = (Bullish AND Bearish[1]) AND (Body > Body[1]) AND (open <= close[1]) AND (close >= open[1])
BearishEngulfing = (Bearish AND Bullish[1]) AND (Body > Body[1]) AND (open >= close[1]) AND (close <= open[1])
CrossOver        = close CROSSES OVER  Average[200,0](close)
CrossUnder       = close CROSSES UNDER Average[200,0](close)
Result           = 0
IF BullishEngulfing THEN
   Result = Result = 1
ELSIF BearishEngulfing THEN
   Result = Result + 2
ENDIF
IF CrossOver THEN
   Result = Result + 10
ELSIF CrossUnder THEN
   Result = Result + 20
ENDIF
IF (Result > 0) AND (Result < 10) THEN
