主题：我写的图表交易系统，请高手指点：

CONBUY:=Long And Not(Ref(Long,1));
CONBUYSHORT:=Short And Not(Ref(Short,1));

CONNo:=OpenPrift>1000 ;

ConTime:=(CURRENTTIME>145920 AND CURRENTTIME<150005);

//不是最后一根Bar，只显示买卖信号（这里给大家提个建议，显示的字体难看啊。。。）

If  Not(IsLastBar) Then Begin

//做多
If ConBuy Then Begin
SellShort(Holding<0,0,ThisClose),TFILTER,ORDERQUEUE;
Buy(Holding=0,1,ThisClose),TFILTER,ORDERQUEUE;
End

//做空
If ConBuyShort Then Begin
Sell(Holding>0,0,ThisClose),TFILTER,ORDERQUEUE;
BuyShort(Holding=0,1,ThisClose),TFILTER,ORDERQUEUE;
End

//空仓

Sell(CONNO  And holding>0,0,ThisClose);
SellShort(CONNO AND holding<0,0,ThisClose);

End

//最后K线

If ConTime And IsLastBar Then Begin

//做多
If ConBuy Then Begin
SellShort(Holding<0,0,ThisClose),TFILTER,ORDERQUEUE;
Buy(Holding=0,1,ThisClose),TFILTER,ORDERQUEUE;
End

//做空
If ConBuyShort Then Begin
Sell(Holding>0,0,ThisClose),TFILTER,ORDERQUEUE;
BuyShort(Holding=0,1,ThisClose),TFILTER,ORDERQUEUE;
End

//空仓
Sell(CONNO  And holding>0,0,ThisClose);
SellShort(CONNO AND holding<0,0,ThisClose);

//纠错
If Long And Holding<0 Then SellShort(1,0,MKT);
If Short  And Holding>0 Then Sell(1,0,MKT);
