通达信SLOPE线性回归参数计算原理

​N1:=1;

N2:=3;

N3:=5;

N4:=8;

N5:=13;

A1:=REF(C,1);

A2:=REF(C,3);

A3:=REF(C,5);

A4:=REF(C,8);

A5:=REF(C,13);

X:=(N1+N2+N3+N4+N5)/5;

Y:=(A1+A2+A3+A4+A5)/5;

分母:=(N1-X)*(N1-X)+(N2-X)*(N2-X)+(N3-X)*(N3-X)+(N4,-X)*(N4-X)+(N5-X)*(N5-X);

分子:=(N1-A1)*(A1-Y)+(N2-A1)*(A2-Y)+(N3-A3)*(A3-Y)+(N4-A4)*(A4-Y)+(N5-A5)*(A5-Y);

 回归斜率:分子/分母,NODRAW;

主升浪: IF(回归斜率<0,MA(C,15),DRAWNULL),COLORBLUE,LINETHICK2;

 AD:=EMA((EMA(C,4)+EMA(C,3)+EMA(C,2)+EMA(C,1))/4,7),COLORBLUE;

AB:=EMA(2*MA(A1,3)*MA(A1,5)/(MA(A1,3)+MA(A1,5)),5);

牛市区:=(EMA(C,24)-EMA(C,6))/2<0;

STICKLINE(牛市区 && AD>AB && 回归斜率<0 && AD>MA(C,13),MA(C,10),MA(C,14),1,0),COLORBLUE;
