源码解析:

S赋值:收盘价上穿EMA2(最高价,30)
X赋值:EMA2(最低价,30)上穿收盘价
WS赋值:上次S距今天数 1
WX赋值:上次X距今天数 1
SS赋值:S的WX日累和上穿0.5
XX赋值:X的WS日累和上穿0.5
当满足条件收盘价>EMA2(最高价,30)时,在EMA2(最高价,30)和EMA2(最低价,30)位置之间画柱状线,宽度为画洋红色,1不为0则画空心柱.
当满足条件收盘价<EMA2(最低价,30)时,在EMA2(最低价,30)和EMA2(最高价,30)位置之间画柱状线,宽度为画蓝色,1不为0则画空心柱.
当满足条件收盘价>EMA2(最高价,150)时,在EMA2(最高价,150)和EMA2(最低价,150)位置之间画柱状线,宽度为COLORLIGHTRED,1不为0则画空心柱.
当满足条件收盘价<EMA2(最低价,150)时,在EMA2(最低价,150)和EMA2(最高价,150)位置之间画柱状线,宽度为COLORLIGHTGREEN,1不为0则画空心柱.

当满足条件开盘价>=收盘价时,在收盘价和开盘价位置之间画柱状线,宽度为画红色,0不为0则画空心柱.
当满足条件收盘价>=开盘价时,在收盘价和开盘价位置之间画柱状线,宽度为画青色,0不为0则画空心柱.
当满足条件SS时,在最低价位置书写文字
当满足条件XX时,在最高价位置书写文字
