参考下面的范例：

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;


ma40:ma(c,40);//40周期均线
ma20:ma(c,20);
kdjjc:cross(k,d);//kdj金叉
kdjsc:cross(d,k);

if count(c<ma20,2)=2 then sell(holding>0,holding,market);//平多

if c>ma40 and kdjjc  then
begin
buy(holding=0,1,MARKET);
end

if count(c>ma20,2)=2 then sellshort(holding<0,holding,market);//平空

if c<ma40 and kdjsc then
begin
buyshort(holding=0,1,MARKET);
end

if time=CLOSETIME(0)  then //收盘平仓，日线以上周期无效。
begin
sell(holding>0,holding,market);
sellshort(holding<0,holding,market);   
end
