早晨之星100之源码（通达信与益盟通用选股）

K1:= REF(OPEN,2)/REF(CLOSE,2) > 1.02;

{第二根K线是十字星 且是最低价和收盘价都是n天之内的最低}

K2:= abs(REF(close,1)-REF(open,1))/REF(open,1)<0.005 and (REF(high,1)-REF(low,1))/abs(REF(close,1)-REF(open,1))>2;

CONDITON2:= ref(low,1)=llv(low,n) and ref(close,1)=llv(close,n);

{第三根K线是中大阳线且收盘价超过第一根K线的收盘 }

K3:=CLOSE/OPEN>1.02 and CLOSE>REF(CLOSE,2);

{可选项，还可以一些严格的条件：中间的K线和两端的K线都有跳空缺口}

CONDITION1:= REF(CLOSE,2)/REF(OPEN,1)>1.01;
CONDITION3:= OPEN/REF(CLOSE,1)>1.01;

{把以上条件联立}

K1 and K2 and K3 and CONDITON2 {and CONDITION2 and CONDITION3};
