MQL5为什么同样的交易函数在模拟盘可以，在实盘中却实行错误？
ulong OpenPosition(const ENUM_ORDER_TYPE type, const double volume, const long magic, const bool record_time = false) { ulong deal_ticket = 0; double sl = 0; double tp = 0; m_trade.SetExpertMagicNumber(magic); RefreshRates(); double ask = m_symbol.Ask(); double bid = m_symbol.Bid(); switch(type) { case ORDER_TYPE_BUY: if(TakeProfit > 0) tp = m_symbol.NormalizePrice(ask + TakeProfit * m_point); if(StopLoss > 0) sl = m_symbol.NormalizePrice(bid - StopLoss * m_point); break; case ORDER_TYPE_SELL: if(TakeProfit > 0) tp = m_symbol.NormalizePrice(bid - TakeProfit * m_point); if(StopLoss > 0) sl = m_symbol.NormalizePrice(ask + StopLoss * m_point); break; } ulong time = GetTickCount64(); if(m_trade.PositionOpen(m_symbol.Name(), type, volume, (type == ORDER_TYPE_BUY) ? ask : bid, sl, tp, PositionComment)) { open_execution = GetTickCount64() - time; bool condtion = true; do { ulong order_ticket = m_trade.ResultOrder(); HistorySelect(iTime(m_symbol.Name(), PERIOD_D1, 0), TimeTradeServer()); int total = HistoryDealsTotal(); for(int i = total - 1; i >= 0; i--) { if(!m_deal.SelectByIndex(i)) continue; if(m_deal.Symbol() != m_symbol.Name()) continue; if(m_deal.Entry() != DEAL_ENTRY_IN) continue; if(m_deal.Order() != order_ticket) continue; printf(StringFormat("open #%%I64u %%s %%.2f %%s at %%.%df done in %%I64u ms", m_symbol.Digits()), m_deal.Order(), (type == ORDER_TYPE_BUY) ? "buy" : "sell", m_deal.Volume(), m_deal.Symbol(), m_deal.Price(), open_execution); if(record_time) last_open_time = m_deal.Time(); deal_ticket = m_deal.Ticket(); condtion = false; } } while(condtion); } return(deal_ticket); }
应该是订单没有交易成功，才返回0
我直接复制你的代码过去就是实盘成功返回ticket的
话说怎么都爱系统自带类，我就见太麻烦，跳来跳去，还不如自己写楼主已经说了很清楚了，在模拟帐户能返回正确的deal ticket， 在实盘只会返回0值 ， 这是由于MT5服务器不同于MT4服务器的订单机制
所以要获取deal ticket， 只能按照我以上的代码来获取，而楼主的代码只适用模拟帐户，在真实帐户中由于需要等待服务器返回真实的deal ticket，
在这等待的过程中， 代码已经实行了， 所以只会一直返回0值，不过我又完善了一下此代码
另外说一下， 系统的自带类的好处是可以省掉很多代码量

我有一个代码块，功能是实行开仓并返回此单的deal ticket
试过很多方法，都行不通，希望懂的高手，请帮我分析分析，谢谢！
