避免同一根K線雙重開倉　[金字塔]

輪詢模式，

aa:enterbars,NODRAW;
bb:EXITBARS,NODRAW;

如圖經(jīng)測試，當(dāng)條K線雙頭平倉開倉，用ENTERBARS<>0 或ENTERBARS>0 進(jìn)行限制，仍出現(xiàn)如圖情況的開倉

請問如何解決，只限制1根K線只做一次平開倉操作？

A:=OPEN-REF(L,1)>X/100*REF(L,1);
IF A>0 AND HOLDING<=0 AND ENTERBARS<>0 THEN
 BEGIN
 SELLSHORT(1,SS,LIMITR,OPEN);
 BUY(HOLDING=0,SS,LIMITR,OPEN);
 END
 
IF HOLDING<0 AND A<1 AND H>=LL+LL*X/100 AND ENTERBARS<>0 THEN
 BEGIN
 SELLSHORT(1,SS,LIMITR,LL+LL*X/100);

 BUY( HOLDING=0,SS,LIMITR,LL+LL*X/100);

 END
