用了很久的黑牛指标，信号少，准确率高，适合波段操作。指标无未来函数

随机找了几个股票截图，大家可以看。

指标无未来函数

RSV1:=(CLOSE-LLV(LOW,21))/(HHV(HIGH,21)-LLV(LOW,21))*10000;
RSV2:=(CLOSE-LLV(LOW,37))/(HHV(HIGH,37)-LLV(LOW,37))*10000;
短线:=SMA(SMA(RSV1,3,1),3,1)+3*STD(CLOSE,21),COLOR00FF00;
中线:=SMA(RSV2,5,1)+2*STD(CLOSE,37),COLORRED;
RSV3:=(CLOSE-LLV(LOW,55))/(HHV(HIGH,55)-LLV(LOW,55))*10000;
长线:=SMA(RSV3,5,1),COLORYELLOW;
极品底:IF((MA(C,5)-C)/C>0.04 AND (MA(C,10)-MA(C,5))/MA(C,5)>0.04 AND 短线<2000 AND 中线<2000 AND 长线<2000,100,0);
