我正在尝试在买入订单之后立即打开卖出订单，但未打开

Question

我正试图弄清楚如何在买入后立即开出卖单，这是行不通的。谁能说出为什么无法打开？

if (LongSetup == True)
 {
    int OrderOpenBuy = OrderSend(Symbol(),
                                 OP_BUY,
                                 BuyLotsToTrade,
                                 Ask,
                                 10,
                                 Ask-100*Point(),
                                 Ask+100*Point(),
                                 "Buy Order",
                                 MagicNo,
                                 0,
                                 clrAzure);
    int PositionIndex;  //
    int TotalNumberOfOrders = OrdersTotal(); 
    bool OrderClosed = false; 

    // close the buy order          
    for(PositionIndex=TotalNumberOfOrders-1; PositionIndex>0; PositionIndex -- )
    { 
        if ( !OrderSelect(PositionIndex, SELECT_BY_POS, MODE_TRADES) ) continue;
        if ( OrderMagicNumber() == MagicNo
             && OrderSymbol() == Symbol()
             && (OrderType() == OP_BUY 
             || OrderType() == OP_SELL));
        {    
            OrderClosed = OrderClose(OrderTicket(), OrderLots(), OrderClosePrice(), 0, clrNONE);
            if(OrderClosed == true) 
            {
               //open sell order

               int OrderOpenSell = OrderSend (Symbol(),
                                              OP_SELL,
                                              SellLotToTrade,
                                              Bid,
                                              10,
                                              Bid+100*Point(),
                                              Bid-100*Point(),
                                              "Sell Order",
                                              0,
                                              0,
                                              clrRosyBrown);
             }
         }
     }
}

还有更多我应该做的事情，或者我想念的是什么？
