求前辈把这个公式该成选股公式，要求出现B点

MA18:EMA(C,18),COLOREEEEEE,LINETHICK2;
红18:IF(MA18>REF(MA18,1),MA18,DRAWNULL),COLOR0000FF,LINETHICK4;
绿18:IF(MA18STICKLINE(MA18>REF(MA18,1),LOW,HIGH,0,0),COLOR0000DD;
STICKLINE(MA18>REF(MA18,1),CLOSE,OPEN,3,0),COLORRED;
STICKLINE(MA18STICKLINE(MA18买进条件:STICKLINE(CROSS(MA18,REF(MA18,1)),OPEN,CLOSE,2.5,0),COLORFF00FF;
DRAWICON(CROSS(MA18,REF(MA18,1)),L*0.98,1);
DRAWICON(CROSS(MA18,REF(MA18,1)),L*0.95,7);

前辈，公式通过了，可是选出来的不是B点出现

MA18:=MA(C,18),COLOREEEEEE,LINETHICK2;
红18:=IF(MA18>REF(MA18,1),MA18,DRAWNULL),COLOR0000FF,LINETHICK4;
绿18:=IF(MA18 CROSS(MA18,REF(MA18,1));
你不是要在买进条件成立的时候买入吗？

ma18:=ema(c,18); 买进:cross(ma18,ref(ma18,1));
