//方法2

/dea:="macd,dea";
//macd:="macd,macd";
//方法1
//input:p(26,20,88,6),s(12,5,15,1),m(9,2,15,1);
//DIFF : EMA(CLOSE,S) - EMA(CLOSE,P);
//DEA  : EMA(DIFF,M);
//MACD1 : 2*(DIFF-DEA), COLORSTICK;

//建立多头进场条件
Long:=cross(diff,dea);
if long then
 begin
sellshort( holding<0,holding,thisclose);
buy( long,1,thisclose);
end
//建立空头进场条件
Short:=cross(dea,diff);
if Short then
 begin 
            sell( holding>0,holding,thisclose);
           buyshort( short,1,thisclose);
          end
