错误4756是 "交易请求发送失败"。如果你在发送订单时出现错误，请检查MqlTradeResult的返回代码。

         //--- send order
         OrderSend(mrequest,mresult);
         // get the result code
         if(mresult.retcode==10009 || mresult.retcode==10008) //Request is completed or order placed
           {
            Alert("An order has been successfully placed with Ticket#:",mresult.order,"!!");
           }
         else
           {
            Alert("The order request could not be completed -error:",GetLastError()," with trade return code ",mresult.retcode);
            ResetLastError();
            return;
           }

根据上面 的Konstantin83，你有无效止损的错误，这意味着你必须在SymbolInfoIntegerSYMBOL_TRADE_STOPS_LEVEL和SYMBOL_TRADE_FREEZE_LEVEL 之外下挂单。

对于ECN类型的经纪商，是否也会返回无效的止损？

当然，你知道答案是否定的。但为什么这么问？

Why do you assume I know the answer is no ? Invalid stops(error 130) is returned on mql4 when SL or TP are sent with OrderSend() to an ECN Broker so I was asking if the same is true with mql5. What error is returned ?

RaptorUK:
为什么你认为我知道答案是否定的？ 当SL或TP用OrderSend()发送到ECN经纪商时，无效止损（错误130）在mql4上被返回，所以我在问mql5是否也是如此。 什么错误被返回？
真的吗？ 这很有趣。我以后要检查一下;D.
 
phi.nuts:
真的吗？ 这很有趣。我稍后要检查它;D.
如果策略测试器的行为类似于经纪商返回的结果，那么当为一个ENUM_SYMBOL_TRADE_EXECUTION 为交易所执行或市场执行 的符号发送SL和TP时，似乎会被忽略，并且不会返回错误。 因此，与mql4相比，事情有很大不同。
 
RaptorUK:
If the Strategy Tester behaviour is similar to what would be returned by a Broker then it seems that SL & TP are ignored when sent for a Symbol whoseENUM_SYMBOL_TRADE_EXECUTION isExchange execution orMarket execution and no error is returned. So things are quite different compared to mql4.

我还发现了一些关于无效止损的问题。 我有一个简单的EA，它在进行交易时带有SL和TP，除非符号是交易所或市场执行，那么它在发送交易时没有设置SL和TP，然后向（TRADE_ACTION_SLTP）发送第二个请求以设置SL和TP。

它在策略测试器中工作正常，所以今天我在模拟账户上试了一下，我一直得到无效止损（错误10016）。 所以我检查了止损水平和冻结水平，它们都是0，我尝试了各种水平的SL和TP，没有任何效果。我可以为现有的头寸手动设置相同的SL和TP，没有任何问题 ... ...所以我添加了一个测试，只在可以选择头寸的情况下放置SL和TP ... ...不再有无效止损，也不再有TRADE_ACTION_SLTP交易请求 :-(

所以我在完成没有TP和SL的初始交易请求和随后发送TP和SL的交易请求之间添加了这段代码 ..

         SelectRetryCount = 1;
         if(SetTPandSL)
            {
            while(!PositionSelect(_Symbol) && SelectRetryCount < 10)
               {
               Sleep(SelectRetryCount * 100); // sleep for SelectRetryCount * 100 mS
               SelectRetryCount++;
               }
            }

如果初始交易请求成功，SetTPandSL被设置为真，如果不成功，就没有必要尝试设置TP和SL。选择头寸，如果失败，会发生100毫秒的睡眠，然后重新选择，如果失败，会发生200毫秒的睡眠，等等，最多尝试9次（共4.5秒）。

我真的不知道我在用mql5做什么，我真的只是在尝试让一些东西工作，希望边做边学......我在这里发现的是正常行为吗？我认为一旦初始交易请求返回10009 - TRADE_RETCODE_DONE，我就可以发送请求来设置TP和SL，是不是这样？

你用什么函数，类/方法来发送/修改你的订单？
