新人对MQL4和MQL5的任何问题，对算法和代码的帮助和讨论

Rewerpool 2018.02.15 11:29 #4631

@Konstantin Nikitin 对你来说更容易！你是个专家！你是个专家。我正在学习!

if(!OrderSelect(i,SELECT_BY_POS)) continue;
     if(OrderSymbol()!=Symbol()) continue;
А это как прочитать? Если (Ордер не выбран) продолжить;
                     Если (Текущий Символ не равен Символу) продолжить; Так? Или как?

Rewerpool:

你怎么看这个？如果（未选择订单）继续。

如果（当前符号不等于符号）继续；对吗？或如何？

操作员继续

Rewerpool 2018.02.15 12:03 #4633

@Konstantin Nikitin 明白了，所以：如果有什么问题，请纠正我。

if(!OrderSelect(i,SELECT_BY_POS)) continue;
Если (Ордер не выбран ордер) начать цикл снова; //(Вернутся в начало функции)
if(OrderSymbol()!=Symbol()) continue;
Если (ОрдерСимвола не равен текущему Графику)начать цикл снова; //(Вернутся в начало функции)

还有一个问题：!"OrderSelect"--是指：没有订单还是没有选中订单？

Rewerpool:

明白了，所以：如果有什么问题，请纠正我！。

如果没有选择顺序，则选择循环的下一个元素

另外，这里有一个问题：!"OrderSelect"--它的意思是：不是一个订单，还是没有选中一个订单？

操作和表达式，看看那里的逻辑操作

@Konstantin Nikitin 把它放在一起是这样的。

   int tip,Ticket;
   double OOP,OSL,OTP;
   int SPREAD    = (int)MarketInfo(Symbol(),MODE_SPREAD);
   if (stoploss<STOPLEVEL) stoploss=0;

for(int i=0; i<OrdersTotal(); i++)
{
     if(!OrderSelect(i,SELECT_BY_POS,MODE_TRADES)) continue;
     if(OrderSymbol()!=Symbol()) continue;
     
     int tip = OrderType();
     if(tip!=OP_BUY && tip!=OP_BUYSTOP && tip!=OP_BUYLIMIT) continue;
     
     // переменные которые будут использоваться в любых ордерах
     int Ticket = OrderTicket();
     double OOP = OrderOpenPrice();
     
     //---

               {
                  if (takeprofit!=0) TP = NormalizeDouble(OOP + takeprofit*Point,Digits); else TP=OTP;
                  if (stoploss!=0)   SL = NormalizeDouble(OOP - (stoploss+SPREAD)* Point,Digits); else SL=OSL;       
                  if (OrderModify(Ticket,OOP,SL,TP,0,White)) Print("STOP_TAKE",Ticket," SL ",OSL," -> ",SL,"   TP ",OTP," -> ",TP);

            if ((OSL==0&&stoploss!=0)||(OTP==0&&takeprofit!=0))
            {  
              if (tip==OP_BUY || tip==OP_BUYSTOP || tip==OP_BUYLIMIT)

               }

               {
                  if (takeprofit!=0) TP = NormalizeDouble(OOP - takeprofit*Point,Digits); else TP=OTP;
                  if (stoploss!=0)   SL = NormalizeDouble(OOP + (stoploss+SPREAD)* Point,Digits); else SL=OSL;

                  else Print(Symbol()," Error STOP_TAKE",GetLastError(),"  Ticket ",Ticket);
               } 
            }
         }
               }
               }
     }
}

对吗？

Rewerpool 2018.02.15 12:40 #4636

增加了更多这样的内容。

Rewerpool 2018.02.15 13:08 #4637

为什么还要这样写呢？

if(!OrderSelect(i,SELECT_BY_POS,MODE_TRADES)) continue;
     if(OrderSymbol()!=Symbol()) continue;

如果你只把EA放在一个符号上，它将在所有的符号上工作？而魔术师将看到他自己的!

完全糊涂了!

Dmitry Romanov 2018.02.15 13:10 #4638

我的朋友们，谁知道如何实现：一个EA可以获得一个指标的绝对值，例如iStohastic()。如何判断指标是否已离开超买或超卖区？

从视觉上看，像一个带有80和20水平的随机指标。

雷沃浦：好吧，你去吧，没有错误。

虽然你在修改EA和其他订单时有完全相同的逻辑。究竟为什么需要区分它们，还不是很清楚。但我认为这个原则是有用的。
