以上语句有错误吗？ＢＫ ＳＰ ＳＫ ＢＰ最后加过滤，TFILTER；可以吗？如果可以加的话，以上原码能不能程式化自动下单吗？如果不能自动化下单，那该怎么改？请老师指点并改成能下单的，急盼，谢谢！

tSELLSHORT(BP and THOLDING<0,THOLDING,MKT);//本身不可能无仓平仓
tBUY(BK and THOLDING =0,1,MKT);//表示持仓为0，才开仓，有过滤作用，指开一次仓
tSELL(SP and THOLDING>0,THOLDING,MKT); //本身不可能无仓平仓
tBUYSHORT(SK and THOLDING=0,1,MKT); //表示持仓为0，才开仓，有过滤作用，指开一次仓
THOLDING =0 与 NOT(tTYPE(1)=1)重复
TFILTER在这里无效
