爱交易指标源码之MACD—完美标记金叉、背离

为了避免遮挡，缩写了名词

低=低位金叉

二金=二次金叉

底背离

三全项

源代码：

diff=ema(close,12) - ema(close,27);

draw(diff,color="red");

dea=ema(diff,9);

draw(dea,color="green");

macd=2 * (diff - dea);

drawIf(macd>0 && ref(macd, 1) >= macd, macd, title="MACD", color="#00C087", showpricevalue=true, style="histogram", showtitle=true);

drawIf(macd>0 && ref(macd, 1) < macd, macd, title="MACD", color="#00C087", showpricevalue=true, style="histogram", fill=false, showtitle=true);

drawIf(macd<=0 && ref(macd, 1) >= macd, macd, title="MACD", color="#ED6160", showpricevalue=true, style="histogram", showtitle=true);

drawIf(macd<=0 && ref(macd, 1) < macd, macd, title="MACD", color="#ED6160", showpricevalue=true, style="histogram", fill=false, showtitle=true);

低位金叉=isCrossUp(diff,dea) && diff < -0.1;

drawStickBetweenIf(低位金叉,0,10,color="yellow",fill=true,linewidth=6);

drawText(低位金叉,10," 低",y=-10,color="white");

jccount=count(isCrossUp(diff,dea),barsFromPrevTrue(dea >= 0));

二次金叉=isCrossUp(diff,dea) && dea < 0 && count(jccount == 2,21) == 1;

drawStickBetweenIf(二次金叉,0,10,color="#ff00ff",fill=true,linewidth=6);

//drawText(二次金叉,dea,1,color="white");

drawText(二次金叉,10," 二金",y=30,color="yellow");

a1=barsFromPrevTrue(refBefore(isCrossUp(diff,dea),1));

底背离=refBefore(close,a1 + 1) > close && diff > refBefore(diff,a1 + 1) && isCrossUp(diff,dea);

drawStickBetweenIf(底背离,0,10,color="#00ff00",fill=true,linewidth=6);

底背="";

drawLineBetweenIfIf(a1 == 0,dea,底背离,dea,color="red");

drawText(底背离,5," 底背离",color="#ff00ff");

a2=barsFromPrevTrue(refBefore(isCrossUp(dea,diff),1));

顶背离=refBefore(close,a2 + 1) < close && refBefore(diff,a2 + 1) > diff && isCrossUp(dea,diff);

顶背="";

drawLineBetweenIfIf(a2 == 0,dea,顶背离,dea,0,color="green");

drawText(低位金叉 && 二次金叉 && 底背离,2,"三全项",color="#0000ff");
