SetOrderMap2AppointedSymbol(symbols, multiples); ?

這個函數能不能在OnBar里使用，能不能多次使用。

如：

?Events
? ? onBar(ArrayRef<Integer> indexs)
? ? { ? ?
? ? //代碼正文
? ? //If(!CallAuctionFilter()) Return;
? ? symbols1 = fRollover[1][0];
?? ?symbols2 = fRollover[0][0];
?? ?multiples = 1;
? ? value1=xaverage(open,LengthShort)-xaverage(open,LengthLong); //value1是9周期指數移動平均減去45周期指數移動平均
? ? bias1=xaverage(value1,n); //bias1是value1的2周期平均
? ? bias=bias1[1];
? ??
? ? ma1=xaverage(open,LengthShort);
? ? ma2=xaverage(open,LengthLong);
