A1:=3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1);
黑:EMA(A1,5)，COLORwhite, NODRAW;;
A4:=((C-LLV(L,21))/(HHV(H,21)-LLV(L,21)))*100;
趋:(MA(3*SMA(A4,6,1)-2*SMA(SMA(A4,5,1),5,1),2))*VAR1NW,COLORYELLOW;
VAR1:=SAR(10,2,18);
IF(VAR1>C,黑,DRAWNULL),COLORGREEN ,LINETHICK2;
IF(VAR1<C,黑,DRAWNULL),COLORRED ,LINETHICK2;

要下:=VAR1>C;
要上:=VAR1<C;

界下a:=要下 AND REF(要上,1);  
界上a:=要上 AND REF(要下,1);
红线起始买开仓，红线消失自动平仓，
绿线起始卖开仓，绿线消失自动平仓
