求老师做预警公式（精确趋势），刚出现黄线预警公式，多谢！！！

M 1.00 300.00 24.00

买入基础:=EMA(C,5)>REF(EMA(C,5),1) AND EMA(C,10)>=REF(EMA(C,10),1);
VAR1:=EMA(INDEXC,5);
VAR2:=EMA(INDEXC,10);
VAR3:=EMA(INDEXC,20);
VAR4:=VAR1>=REF(VAR1,1) AND 买入基础;
VAR5:=VAR2>=REF(VAR2,1) AND 买入基础;
VAR6:=VAR3>=REF(VAR3,1) AND 买入基础;

{以下语句是股道趋势及买卖点}
A1:=LLV(LOW,5)=LLV(LOW,45) AND CLOSE>=OPEN*1.04;
A2:=CLOSE>(REF(HIGH,1)+REF(LOW,1))/2;
买入:=A1 AND A2;
A3:=REF(CLOSE,1);
A4:=SMA(MAX(CLOSE-A3,0),6,1)/SMA(ABS(CLOSE-A3),6,1)*100;
卖出=CROSS(80,A4);
底吸线: 10,COLOR1090FF;

高抛线: 90,COLOR109C10;
A5:=LLV(LOW,18);
A6:=HHV(HIGH,18);
A7:=EMA((CLOSE-A5)/(A6-A5)*100,13);
股道趋势:EMA(0.618*REF(A7,1)+0.382*A7,3),COLORYELLOW,LINETHICK2;

A8:=MA(C,1)/MA(REF(C,18),18)*100;
A9:=MA(FORCAST(A8,20),6);
攻击点:=IF(FILTER(CROSS(A8,A9),5)=1,50,0);{买1}
DRAWICON(攻击点,股道趋势*0.98,1);
DRAWICON(卖出,股道趋势,2);{卖}
DRAWICON(买入,股道趋势,1);{买2};
