DIFF:EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);//短周期與長(zhǎng)周期的收盤價(jià)的指數(shù)平滑移動(dòng)平均值做差。 DEA:EMA(DIFF,M);//DIFF的M個(gè)周期指數(shù)平滑移動(dòng)平均 2*(DIFF-DEA),COLORSTICK;//DIFF減DEA的2倍畫柱狀線 MA5:MA(C,139); AA:CROSSDOWN(DIFF,DEA)&&COUNT(CROSSDOWN(DIFF,DEA),BARSBK)=1;//MACD死叉并且是BK信號(hào)之后第一個(gè)死叉 AB:CROSS(DIFF,DEA)&&COUNT(CROSS(DIFF,DEA),BARSSK)=1;//MACD金叉并且是SK信號(hào)之后第一個(gè)金叉 C>MA5 &&EXIST(CROSSDOWN(DIFF,DEA),BARSBK) AND C>VALUEWHEN(AA,HHV(H,BARSBK)) AND BKVOL=0,BK(1);//多頭加倉(cāng) C<MA5 &&EXIST(CROSS(DIFF,DEA),BARSSK) AND C<VALUEWHEN(AB,LLV(L,BARSSK)) AND SKVOL=0,SK(1);//空頭加倉(cāng) ISLASTBK &&EXIST(CROSSDOWN(DIFF,DEA),BARSBK) AND C>VALUEWHEN(AA,HHV(H,BARSBK)) AND BKVOL>=1,BK(1);//多頭加倉(cāng) ISLASTSK &&EXIST(CROSS(DIFF,DEA),BARSSK) AND C<VALUEWHEN(AB,LLV(L,BARSSK)) AND SKVOL>=1,SK(1);//空頭加倉(cāng)
文華技術(shù)人員：?以開倉(cāng)條件為例： 首次開倉(cāng)條件是這樣編寫的：
C>MA5 &&EXIST(CROSSDOWN(DIFF,DEA),BARSBK) AND C>VALUEWHEN(AA,HHV(H,BARSBK)) AND BKVOL=0,BK(1);
其中這兩個(gè)條件，是根據(jù)BK信號(hào)后出現(xiàn)的條件來判斷，而首次出信號(hào)之前不可能存在BARSBK，所以首次開倉(cāng)不能滿足。
這樣調(diào)整：
C>MA5 &&(COUNTSIG(BK,BARPOS)=0||(EXIST(CROSSDOWN(DIFF,DEA),BARSBK) AND C>VALUEWHEN(AA,HHV(H,BARSBK)) )) AND BKVOL=0,BK(1);C<MA5&&(COUNTSIG(SK,BARPOS)=0 ||(EXIST(CROSS(DIFF,DEA),BARSSK) AND C<VALUEWHEN(AB,LLV(L,BARSSK)) )) AND SKVOL=0,SK(1);//空頭加倉(cāng)
