 源碼解析：

輸出RUNMODE:0
輸出 INPUT:LENGTH(20)
輸出 VARIABLE:STOPLINE=0
 邏輯判斷 BARPOS<=30 THEN EXIT
UP賦值:統(tǒng)計(jì)LENGTH日中滿足收盤價(jià)>昨收的天數(shù)
DOWN賦值:統(tǒng)計(jì)?日中滿足OND賦值:UP/DOWN>=2/3的天數(shù)
ENTRYSHORTCOND賦值:DOWN/UP>=2/3
UPPERBAND賦值:昨日LENGTH日內(nèi)最高價(jià)的最高值
LOWERBAND賦值:昨日LENGTH日內(nèi)最低價(jià)的最低值
HH賦值:昨日最高價(jià)
LL賦值:昨日最低價(jià)
 邏輯判斷 HOLDING=0 THEN BEGIN 邏輯判斷 昨日ENTRYLONGCOND THEN BEGIN BUY(1,1,LIMITR,開盤價(jià))
STOPLINE賦值:LOWERBAND
 END 邏輯判斷 昨日ENTRYSHORTCOND THEN BEGIN BUYSHORT(1,1,LIMITR,開盤價(jià))
STOPLINE賦值:UPPERBAND
STOPLINE賦值:LOWERBAND
 邏輯判斷 最低價(jià)<=STOPLINE THEN SELL(1,HOLDING,LIMITR,開盤價(jià)和STOPLINE的較小值)
STOPLINE賦值:UPPERBAND
 邏輯判斷 最高價(jià)>=STOPLINE THEN SELLSHORT(1,HOLDING,LIMITR,開盤價(jià)和STOPLINE的較大值)
輸出 END SS:STOPLINE,線寬為0
 當(dāng)滿足條件HOLDING<>0時(shí),在STOPLINE位置畫11號(hào)圖標(biāo)
輸出 盈虧:ASSET-500000,NOAXIS,畫黃色,線寬為2
