안녕하세요 예스스탁입니다 함수는 별도로 사용자함수로 만드셔야 합니다. 1 사용자함수 함수명 : HullMA 반환값형 : 숫자형 input : price(Numeric),length(Numeric); Vars: wma1(0), wma2(0), diff(0), sqrtLen(0), result(0); wma1 = WMA(price, length / 2); wma2 = WMA(price, length); diff = 2 * wma1 - wma2; sqrtLen = MaxList(1, SquareRoot(length)); result = WMA(diff, sqrtLen); HullMA = result; 2 plot3은 기본차트와 Y축이 다른 지표이므로 별도로 만드셔야 합니다.
