请问那位老师给这个均线变色指标加均线交叉条件多空能够用红绿箭头显示_20均线变色指标公式

推荐回答：

n:=15;k:=8;direction:=abs(close-ref(close,n));volatility:=sum(abs(close-ref(close,1)),n);er:=direction/volatility;fsc:=2/(2+1);ssc:=2/(30+1);sc:=er*(fsc-ssc)+ssc;scsq:=sc*sc;kma:dma(close,scsq),colorwhite,linethick1;threshold:=std(kma-ref(kma,1),20)*k/10;buy0:=kma-llv(kma,4)>threshold;sell0:=hhv(kma,4)-kma>threshold;partline(buy0=1 and sell0=0,kma),colorred,linethick2;partline((buy0=0 and sell0=0) or (buy0=1 and sell0=1),kma),colorwhite,linethick1;partline(buy0=0 and sell0=1,kma),colorgreen,linethick2;b8:=ma(close,1);d8:=ma(close,5);drawicon(buy0=1 and ref(buy0,1)=0 and sell0=0,kma,4);drawicon(buy0=0 and ref(sell0,1)=0 and sell0=1,kma,5);{是要这样的吧}
