主题：帮忙写一个kdj

一80是KDJ指标的值  在最右边有 显示20 40 60  80  100 

 input:n(9,1,100,10),p1(3,2,40,4),p2(3,2,40,4)；//参数设置


RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
K:SMA(RSV,P1,1);
D:SMA(K,P2,1);
J:3*K-2*D;

kdjjc:cross(k,d);//kdj金叉
kdjsc:cross(d,k);

if kdjjc and k>=80 and j>=80 and d>=80 then //kdj金叉且kdj值均大于80  平空开多
begin
sellshort(holding<0,holding,MARKET);
buy(holding=0,1,MARKET);
end

if kdjsc and k<=20 and d<=20 and j<=20 then
begin
sell(holding>0,holding,MARKET);
buyshort(holding=0,1,MARKET);
end
