精确买卖指标，没有未来函数(通达信副图源码)

精确买卖指标用法：当白线在0轴下面向上交叉绿线变成黄线是买入；当红线向下交叉绿线变白线时卖出。就这么简单。

{ 参数缺省值 SHORT: 26 1 100 LONG: 12 1 100 M: 9 1 100 }

DIF:=((EMA(CLOSE,SHORT)-EMA(CLOSE,LONG)))*-1;

DEA:=EMA(DIF,M);

MACD:=2*(DIF-DEA);

A4:=BARSLAST(REF(CROSS(DIF,DEA),1));

B1:=REF(C,A4+1)>C AND REF(DIF,A4+1)<DIF AND CROSS(DIF,DEA);

DRAWTEXT(FILTER(B1>0,5),DIF+0.2,'背离'),COLORYELLOW;

操盘:STICKLINE(MACD>=0 AND MACD>=REF(MACD,1),0,MACD,4,1),COLORRED{COLOR6058FF};

减仓:STICKLINE(MACD>=0 AND MACD< REF(MACD,1),0,MACD,4,0),COLORRED{COLOR6058FF};

反弹:STICKLINE(MACD<0 AND MACD>=REF(MACD,1),0,MACD,4,1),COLORYELLOW{COLORFFFF00};

寻底:STICKLINE(MACD<0 AND MACD< REF(MACD,1),0,MACD,4,0),COLORFFFF00;

空仓:0,COLORWHITE;
