条件是必须在60日均线才可以开多开空

这句怎么理解，在60日均线的什么位置做什么操作？

MAH:MA(HIGH,30);
MAL:MA(LOW,30);
MAC:MA(CLOSE,30);
ma60:ma(c,60);
kd1:cross(h,mah);
kk1:cross(mal,l);
if time>092500 and kd1 then begin
sellshort(holding<0,holding,market);
buy(h>ma60 and holding=0,1,market);
end
if time>092500 and kk1 then begin
sell(holding>0,holding,market);
buyshort(l<ma60 and holding=0,1,market);
end
//止损
if enterprice-l>=6 and holding>0 then sell(1,holding,market);
if h-enterprice>=6 and holding<0 then sellshort(1,holding,market);
//止盈
if h-enterprice>=20 and holding>0 then sell(1,holding,market);
if enterprice-l>=20 and  holding<0 then sellshort(1,holding,market);

//收盘前平仓
if time>=151100 then begin
sell(holding>0,holding,market);
sellshort(holding<0,holding,market);
end
