A函数的写法，我的写法有问题吗，也没法回测，求指导

// 空头开仓 - 使用A函数 If(EntryShortSignal && Not OrderSent_Short) { Numeric EntryPriceShort; If(OrderType == "限价单") { EntryPriceShort = Min(Open, DonchianLow) - Slippage * MinMove * PriceScale; // 发送限价单 A_SendOrder(Enum_Sell, Enum_Entry, Lots, EntryPriceShort); Commentary("发送空头限价开仓单，价格：" + Text(EntryPriceShort)); } Else { EntryPriceShort = Close - Slippage * MinMove * PriceScale; // 发送市价单 A_SendOrder(Enum_Sell, Enum_Entry, Lots, Close - Slippage * MinMove * PriceScale); Commentary("发送空头市价开仓单"); } MP_count = 1; PriceA = EntryPriceShort; EntryPrice = PriceA; MaxProfit = 0; stopLossPrice = PriceA + StopLossMulti * ATR0; OrderSent_Short = True; OrderSent_Long = False; OrderBarCount = 0; Commentary("空头开仓信号，手数：" + Text(Lots) + "，当前周期OTT方向：" + Text(dir0[1]) + "，RSI：" + Text(RSIVale[1])); } } // 订单超时管理 OrderBarCount = OrderBarCount + 1; If(OrderBarCount > 3) { If(OrderSent_Long) { OrderSent_Long = False; Commentary("多头订单超时未成交，取消"); }
