3 Black Crows, 3 White Soldiers

Detection of the candlestick pattern 3 Black Crows and 3 White Soldiers. The indicator contains extra parameters for detecting any sequence of alternative numbers of crows/soldiers (e.g. 2, 3, 4, etc). Extra optional condition is inserted to take into account the minimum ratio between the body and the range of candle. (e.g. the bodies must be at least 70% of the total candle)
