标题：修改指标

我菜，不会修改，麻烦老师帮忙修改一下，

K线收盘价在60日均线之上，MACD在零轴之上金叉开仓做多单，止损跌破20日均线止损，反之K线收盘价在60日均线之下，MACD在零轴之下死叉开仓做空单，止损收盘价在20日均线之上止损，

input:p(26,20,100,8),s(12,5,40,4),m(9,2,60,6)；//参数设置
VARIABLE:mark1:=0,mark2:=0;

DIFF : EMA(CLOSE,S) - EMA(CLOSE,P);
DEA  : EMA(DIFF,M);
MACD1 : 2*(DIFF-DEA), COLORSTICK;

ma60:ma(c,60);
ma20:ma(c,20);

majc:cross(ma20,ma60);
masc:cross(ma60,ma20);

macdjc:cross(diff,dea);//macd金叉
macdsc:cross(dea,diff);

if majc then 
begin
sellshort(holding<0,holding,market);//平空
buy(holding=0,majc,market);    //开多
mark1:=0;
end

if masc then
begin

mark1:=mark1+1;
end

if macdsc and holding<0 and mark2<=2 then
begin
buyshort(1,1,MARKET);
mark2:=mark2+1;
