函数使用

SetOrderMap2AppointedSymbol(symbols, multiples); 这个函数能不能在OnBar里使用，能不能多次使用。 如： Events onBar(ArrayRef<Integer> indexs) { //代码正文 //If(!CallAuctionFilter()) Return; symbols1 = fRollover[1][0]; symbols2 = fRollover[0][0]; multiples = 1; value1=xaverage(open,LengthShort)-xaverage(open,LengthLong); //value1是9周期指数移动平均减去45周期指数移动平均 bias1=xaverage(value1,n); //bias1是value1的2周期平均 bias=bias1[1]; ma1=xaverage(open,LengthShort); ma2=xaverage(open,LengthLong); http://mp.weixin.qq.com/s/mddsIyfTK_IN3zn2ojoKaw if (ma1[1]>=ma2[1] and MarketPosition==0 and Bias[2]>bias[1] and Bias[1] <Bias and Bias<BIASLength) //做多：condition1为真，倒数第二根k线的Bias变量>倒数第一根k线的Bias变量，倒数第一根k线的Bias变量<当前k线的Bias变量，Bias变量<6 { SetOrderMap2AppointedSymbol(symbols2, multiples); Buy(0,open);//下一k线做多 } if (ma1[1]<ma2[1])//平多：如果9周期指数移动平均下穿45周期指数移动平均 { sell (0,open); //下一k线平多 } if (ma1[1]<=ma2[1] and MarketPosition==0 and Bias[2]<bias[1] and Bias[1] >Bias and Bias<BIASLength)//做空：condition2为真，倒数第二根k线的Bias变量<倒数第一根k线的Bias变量，倒数第一根k线的Bias变量>当前k线的Bias变量，Bias变量<6 { SetOrderMap2AppointedSymbol(symbols2, multiples); sellshort (0,open); //下一k线做空 } if (ma1[1]>ma2[1])//平空：如果9周期指数移动平均上穿45周期指数移动平均 { buytocover (0,open); //下一k线平空 } If(GetDicTime(fRollover, 0) <> GetDicTime(fRollover, 1) And fRollover[0][1] <> InvalidString And fRollover[0][2] <> InvalidString) { PlotBool("换月", True); //myRollover = rClose / Value(fRollover[0][2]); Commentary("原合约收盘价：" + fRollover[0][1]); Commentary("新合约收盘价：" + fRollover[0][2]); Commentary("symbols：" + fRollover[1][0]); Commentary("multiples：" + Text(multiples[1])); //Lots = Max(1, Round(CurrentContracts * Value(fRollover[0][1]) / Value(fRollover[0][2]),0)); If(MarketPosition == 1) { SetOrderMap2AppointedSymbol(symbols1, multiples); Sell(0, Value(fRollover[0][1]),Enum_Signal_UnCorrectPrice); SetOrderMap2AppointedSymbol(symbols2, multiples); Buy(0, Value(fRollover[0][2]),Enum_Signal_UnCorrectPrice); } Else If(MarketPosition == -1) { SetOrderMap2AppointedSymbol(symbols1, multiples); BuyToCover(0, Value(fRollover[0][1]),Enum_Signal_UnCorrectPrice); SetOrderMap2AppointedSymbol(symbols2, multiples); SellShort(0, Value(fRollover[0][2]),Enum_Signal_UnCorrectPrice); } }}
