请问怎么可用均线数值+-2*MINDIFF能当开仓价

忠意线割-ShiMan

请问怎么可用均线数值+-2*MINDIFF能当开仓价,我这样做法，软件提示不行，指标编辑测试通不过:

mj:=INTPART(ref(MA(c,50),1))+2*MINDIFF;

平空:SELLSHORT(开多平空条件,0,MARKET),ORDERQUEUE;
开多:BUY(开多条件 AND holding<=0,1,Mj),ORDERQUEUE;  
平多:SELL(开空平多条件,0,MARKET),ORDERQUEUE;
开空:BUYSHORT(开空条件 AND holding>=0,1,Mj),ORDERQUEUE;

mj:=INTPART(ref(MA(c,50),1))+2*MINDIFF;

平空:SELLSHORT(开多平空条件,0,MARKET),ORDERQUEUE;
开多:BUY(开多条件 AND holding<=0,1,limitr,Mj),ORDERQUEUE;  
平多:SELL(开空平多条件,0,MARKET),ORDERQUEUE;
开空:BUYSHORT(开空条件 AND holding>=0,1,limitr,Mj),ORDERQUEUE;
