源碼解析:

輸出INPUT:K(0.7,0.1,1,0.1)
DIST1賦值:上次日>昨日日距今天數+1
DIST2賦值:DIST1日前的DIST1
PREDAYHIGH賦值:DIST1日前的DIST2日內最高價的最高值
PREDAYLOW賦值:DIST1日前的DIST2日內最低價的最低值
PREDAYCLOSE賦值:DIST1日前的收盤價
PREDAYRANGE賦值:PREDAYHIGH-PREDAYCLOSE和PREDAYCLOSE-PREDAYLOW的較大值
DAYOPEN賦值:DIST1-1日前的開盤價
UPPERBAND賦值:DAYOPEN+K*PREDAYRANGE
LOWERBAND賦值:DAYOPEN-K*PREDAYRANGE
