取每次开仓价格出错

因为是以时间为开仓信号（开仓信号有5个），平仓想以每次开仓价格上涨1%止损，下跌4%止盈（5个开仓信号单独计算出场），结果一直算的都是持仓均价，请问如何修正？ 代码如下 Params Numeric TIME1(0.092000); Numeric TIME2(0.100000); Numeric TIME3(0.110000); Numeric TIME4(0.140000); Numeric TIME5(0.145800); Vars Numeric B1; Numeric B2; Numeric B3; Numeric B4; Numeric B5; Events OnBar(ArrayRef<Integer> indexs) { { If(Time==TIME1) SellShort(0,CLOSE); B1=LastEntryPrice; Commentary("B1= "+Text(B1)); If(C>(B1*1.01) Or C<(B1*0.94) ) BuyToCover(0,CLOSE); } { If(Time==TIME2) SellShort(0,CLOSE); B2=LastEntryPrice; Commentary("B2= "+Text(B2)); If(C>(B2*1.01) Or C<(B2*0.94) ) BuyToCover(0,CLOSE); } { If(Time==TIME3) SellShort(0,CLOSE); B3=LastEntryPrice; Commentary("B3= "+Text(B3)); If(C>(B3*1.01) Or C<(B3*0.94) ) BuyToCover(0,CLOSE); } { If(Time==TIME4) SellShort(0,CLOSE); B4=LastEntryPrice; Commentary("B4= "+Text(B4)); If(C>(B4*1.01) Or C<(B4*0.94) ) BuyToCover(0,CLOSE); } { If(Time==TIME5) SellShort(0,CLOSE); B5=LastEntryPrice; Commentary("B5= "+Text(B5)); If(C>(B5*1.01) Or C<(B5*0.94) ) BuyToCover(0,CLOSE); } }
