长线指标改选股预警公式

编写要求：

是否有高手把指标出现“低吸”时预警。 多方趋势:((7)*(SMA(((CLOSE-LLV (LOW,27))/(HHV(HIGH,27)-LLV(LOW,27)))*(30),4,1))-(3)*(SMA(SMA(((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27)))*(30),4,1),3,1))-SMA(SMA(SMA(((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27)))*(30),4,1),3,1),2,1)),COLOR0000FF; 空方趋势:(EMA(MA(多方趋势,5),7)),COLORF0F000; STICKLINE((多方趋势>78) AND (多方趋势>=空方趋势),78,多方趋势,5,1),COLOR00FF00; STICKLINE((空方趋势<=多方趋势),空方趋势,多方趋势,3,0),COLOR0000FF; STICKLINE((空方趋势>多方趋势),多方趋势,空方趋势,3,0),COLORF0F000; STICKLINE((空方趋势<14) AND (空方趋势>多方趋势),多方趋势,20,3,0),COLOR00FFFF; TJ:=FILTER((空方趋势<14) AND (空方趋势>多方趋势),6); DRAWTEXT(TJ,40,'低吸'),COLORFFFFFF; 探测金矿:(空方趋势<12) AND (空方趋势<=多方趋势),COLOR00FFFF; 选金股:CROSS(多方趋势,空方趋势) AND (空方趋势<22),COLOR0000FF; DRAWTEXT(CROSS(多方趋势,空方趋势) AND (空方趋势<22),30,'黑马'),COLOR00FFFF; 中间线:50,COLORFFFFFF,POINTDOT;

解答：

?多方趋势:=((7)*(SMA(((CLOSE-LLV (LOW,27))/(HHV(HIGH,27)-LLV(LOW,27)))*(30),4,1))-(3)*(SMA(SMA(((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27)))*(30),4,1),3,1))-SMA(SMA(SMA(((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27)))*(30),4,1),3,1),2,1));

空方趋势:=(EMA(MA(多方趋势,5),7));
