DC1:=5*MINDIFF;
DC2:=10*MINDIFF;
VARIABLE:A=0;
VARIABLE:B=0;

KD:=OPEN+DC1 AND HOLDING=0;          //开多条件
//DZK:=;          //多转空
KK:=OPEN-DC1 AND HOLDING=0;          //开空条件
//KZD:=;          //空转多
开空:BUYSHORT(KK,1,MARKET);     //开空信号
开多:BUY(KD,1,MARKET);          //开多信号
IF A<C THEN A=C;
IF A>=C+DC2 AND HOLDING>0 THEN
BEGIN
SELL(HOLDING>0,HOLDING,MARKET);
BUYSHORT(HOLDING=0,1,MARKET);
END
IF B>C THEN B=C;
IF B<=C+DC2 AND HOLDING<0 THEN
BEGIN
SELLSHORT(HOLDING<0,HOLDING,MARKET);
BUY(HOLDING=0,1,MARKET);
