ADX(기간)

매개변수 설명

• "기간": Numeric, 최근 N개봉 기간값을 입력

<aside> 📘 계산

PDM = (당일고가-전일고가 > 0) 이고 (당일고가-전일고가 > 전일저가-당일저가) 이면, (당일고가-전일고가) 이고, 아니면 0. MDM = (전일저가-당일저가 > 0) 이고 (당일고가-전일고가 < 전일저가-당일저가) 이면, (전일저가-당일저가) 이고, 아니면 0. PDMMA = (+DM)의 Period 일 이동평균 MDMMA = (-DM)의 Period 일 이동평균 DX = PDMMA-MDMMA의 절대값 / (PDMMA + MDMMA) ×100 ADX = DX의 Period 일 이동평균
