A函数写法问题

老师好，刚刚开始学习A函数的策略写法，请问下面2段代码，哪种是正确的？我自己试了下，都可以运行。-----------------------------------第一种------------------------------------------ //多单模块 if(BarStatus == 2 && num_d == 0 && kd ) { FillPrice_b=Q_AskPrice; Bool ret = A_SendOrder(Enum_Buy, Enum_Entry,lot,Q_AskPrice); if(ret) { num_d = num_d + 1; } } if(BarStatus == 2 && num_d > 0 && H>FillPrice_b+2*nnn*mp) { Bool ret = A_SendOrder(Enum_Sell, Enum_Exit, lot, Q_BidPrice); num_d = -1; } if(BarStatus == 2 && num_d > 0 && L<FillPrice_b-nnn*mp) { Bool ret = A_SendOrder(Enum_Sell, Enum_Exit, lot, Q_BidPrice); num_d = -1; }-----------------------------------第二种------------------------------------------ //多单模块 if(BarStatus == 2 && A_BuyPosition == 0 && kd ) { A_SendOrder(Enum_Buy, Enum_Entry,lot,Q_AskPrice); } if(BarStatus == 2 && A_BuyPosition > 0 && H>A_BuyAvgPrice +2*nnn*mp) { A_SendOrder(Enum_Sell, Enum_Exit, lot, Q_BidPrice); } if(BarStatus == 2 && A_BuyPosition > 0 && L<A_BuyAvgPrice -nnn*mp) { A_SendOrder(Enum_Sell, Enum_Exit, lot, Q_BidPrice); }
