源碼解析:

S賦值:收盤價上穿EMA2(最高價,30)
X賦值:EMA2(最低價,30)上穿收盤價
WS賦值:上次S距今天數 1
WX賦值:上次X距今天數 1
SS賦值:S的WX日累和上穿0.5
XX賦值:X的WS日累和上穿0.5
當滿足條件收盤價>EMA2(最高價,30)時,在EMA2(最高價,30)和EMA2(最低價,30)位置之間畫柱狀線,寬度為畫洋紅色,1不為0則畫空心柱.
當滿足條件收盤價<EMA2(最低價,30)時,在EMA2(最低價,30)和EMA2(最高價,30)位置之間畫柱狀線,寬度為畫藍色,1不為0則畫空心柱.
當滿足條件收盤價>EMA2(最高價,150)時,在EMA2(最高價,150)和EMA2(最低價,150)位置之間畫柱狀線,寬度為COLORLIGHTRED,1不為0則畫空心柱.
當滿足條件收盤價<EMA2(最低價,150)時,在EMA2(最低價,150)和EMA2(最高價,150)位置之間畫柱狀線,寬度為COLORLIGHTGREEN,1不為0則畫空心柱.

當滿足條件開盤價>=收盤價時,在收盤價和開盤價位置之間畫柱狀線,寬度為畫紅色,0不為0則畫空心柱.
當滿足條件收盤價>=開盤價時,在收盤價和開盤價位置之間畫柱狀線,寬度為畫青色,0不為0則畫空心柱.
當滿足條件SS時,在最低價位置書寫文字
當滿足條件XX時,在最高價位置書寫文字
