主题：请帮忙写个MACD策略

帮我写个
做多单：MACD快慢线上穿0轴做多，快慢线在0轴上方第一次金叉加仓多单，第二次金叉加仓多单，第三次金叉加仓多单，
平多单：在快慢线下穿0轴平多单
做空单：MACD快慢线下穿0轴做空，快慢线在0轴下方第一次死叉加仓空单，第二次死叉加仓空单，第三次死叉又加仓空单，
平空单：在快慢线上穿0轴平空单

 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;

ma120:ma(c,120);
ma60:ma(c,60);

majc:cross(ma60,ma120);
masc:cross(ma120,ma60);

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
sell(holding>0,holding,market);//平多
buyshort(holding=0,masc,market);//开空     
mark2:=0;
end



if macdjc and holding>0 and mark1<=2  then //加多仓
begin
buy(1,1,MARKET);
mark1:=mark1+1;
end

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