将波段买入、波段卖出做选股公式

编写要求：

a2:="主图二.a2";a21:=REF(a2,1);a2斜率:=((a2-a21)/a21*100)*10;a5:="主图二.a5";a51:=REF(a5,1);a5斜率:=((a5-a51)/a51*100)*10;a10:="主图二.a10";a30:="主图二.a30";小线多头:=COUNT(a2>a5 AND a5>a10 AND a10>a30,1);今涨停:=C/REF(C,1)>1.06;n内有:=count(今涨停,7);价触a2:=H-a2>=0;{价上:=CROSS(C,a5);}大涨卖出:a2斜率8 and 小线多头 and 价触a2 and n内有;触线卖出:a2斜率c,1);R1:=((LLV(LOW,5) = LLV(LOW,45)) AND (CLOSE >= (OPEN * 1.04)));R2:=(CLOSE > ((REF(HIGH,1) + REF(LOW,1)) / 2));R3:=REF(CLOSE,1);R4:=((SMA(MAX((CLOSE - R3),0),6,1) / SMA(ABS((CLOSE - R3)),6,1)) * 100);波段买入:R1 AND R2,STICK,COLOR16EB41;波段卖出:CROSS(80,R4),STICK,COLOR3820E1;A10:="主图二.a10";价上a10:=c>a10;前天:=REF(A10,1);A10斜率:=((A10-前天)/前天*100)*10;上a10:价上a10 and A10斜率>6;

解答：

 波段买入:llv(l,5)=llv(l,45) and c>=o*1.04 and c>(ref(h,1)+ref(l,1))/2;
