Le biblioteche funzionano?

Ho visto un video da qualche parte in rete su come smontare questa cosa, ma ha bisogno di aprire qualcosa durante la creazione, che siano le testate o qualcos'altro. Ho ricompilato il codice su 64KA e ha funzionato. Bene, si scopre che su 64ka il puntatore a 8 byte è già visto non troppo male e ci possono essere altre differenze critiche che si dovrebbe fortemente giocare con questa domanda. Vorrei semplicemente lavorare con il compilatore a 32 bit per il debug e ho alcune idee specializzate per loro.

 
Potete dirmi perché il doppio 0,00134 non è divisibile per 30?
dà un numero intero e un numero infinito dopo il punto decimale
Dovrebbe essere circa 0,00004

Print( DoubleToString(0.00134/30) ); 0.00004467

Vitaly, se non lo stampi, i calcoli interni mostreranno 0,00004.... o 5.666666.....e ?
O è la stessa cosa?

O è la stessa cosa?

i calcoli interni includono solo questo (un intero esadecimale di otto byte)

ciao! qualcuno conosce un duplicatore sensato di trade da MT4 al Quick exchange?
 

Buon pomeriggio. Aiuto


Ho un codice senza controllare la presenza di ordini aperti.

Apre gli ordini secondo la logica stabilita, ma apre sia ordini di acquisto che di vendita

Lavoreremo con questi ordini.

//non deve controllare l'ordine se è aperto.


Se si abilita il controllo, allora gli ordini non vengono aperti come vorremmo.
Se vogliamo evitare i contrordini, dovremmo controllare il primo ordine da aprire e poi aprire lo stesso tipo fino a quando l'ultimo tipo di ordine viene chiuso e poi tornare alla logica del controllo delle condizioni di apertura.

int TypeOrder(int OrType)
{
 int count = 0;
  for(int i = OrdersTotal(); i>=0; i++ )
     {
      if (OrderSelect(i,SELECT_BY_POS,MODE_TRADES))
         {
          if (OrderSymbol() == _Symbol && OrderType() == OrType && OrderMagicNumber() == Magic)
             {
              count++;
             }
         }
     }return (count);
}

E come indicare questo non si capisce.
C'è qualcuno là fuori che può dare una spinta a capire?

Grazie per qualsiasi suggerimento.

Grazie. La logica era corretta, rendere il contatore solo corretto e specificare la condizione correttamente

if (CountTrades() == 0 && body > 0) BuyOpen();     // Если нет открытых и сигнал бай
   if (CountTrades() == 0 && body < 0) SellOpen();    // Если нет открытых и сигнал селл
   if (CountTrades(0) > 0 && body > 0) BuyOpen();     // Если есть открытые бай и сигнал бай
   if (CountTrades(1) > 0 && body < 0) SellOpen();    // Если есть открытые селл и сигнал селл

Grazie. Ci darò un'occhiata.

Buon pomeriggio. Ecco una domanda. Ho una rete a strascico.

void Trail()
{
 if(iTrailStart <= 0.0)return; 
 double tp,sl_lev;
 for(int i=OrdersTotal()-1; i>=0; i--)
    {
     if(OrderSelect(i, SELECT_BY_POS,MODE_TRADES))
       {
        if(OrderSymbol() == Symbol() && OrderMagicNumber() == Magic)
          {
           if(OrderType() == OP_BUY) 
             {
              if(iTrailTakeProfit > 0.0)
                {
                tp=OrderTakeProfit() + NormalizeDouble(iTrailTakeProfit * Point(),_Digits);
                if(NormalizeDouble(((tp - OrderTakeProfit())) < 0.0,Digits))return;
                tp = OrderTakeProfit();
                }else tp = 0.0;
              if(OrderProfit() + OrderSwap() + OrderCommission() > MarketInfo(Symbol(), MODE_TICKVALUE) * iTrailStart * OrderLots())return;
                {
                 if(NormalizeDouble(Bid - OrderOpenPrice() <= iTrailStart * Point(),Digits))return;
                   {
                    if(OrderStopLoss()== 0.0 && NormalizeDouble((Bid-OrderStopLoss()) <= iTrailDist * Point(),_Digits))return;
                      {
                      if(iTrailStep > 0.0 && OrderStopLoss()==0.0 && NormalizeDouble((Bid - OrderStopLoss() - iTrailDist * Point() < iTrailStep * Point()),_Digits))return;
                        {
                         sl_lev = NormalizeDouble(Bid - iTrailDist * Point(),_Digits);
                         if(NormalizeDouble((Bid - sl_lev) < MarketInfo(Symbol(),MODE_STOPLEVEL) * Point,Digits))return;
                           {
                            if (!OrderModify(Forder,OrderOpenPrice(),OrderStopLoss() + iTrailStart * Point,OrderTakeProfit(),OrderExpiration()))
                            Print("Не удалось модифицировать стоплосс ордера №",OrderTicket(),". Ошибка: ",GetLastError());
                           }
                        }
                      }
                   }
                }
             }
           if(OrderType() == OP_SELL)
             {
              if(iTrailTakeProfit > 0.0)
                {
                 tp=OrderProfit() - NormalizeDouble(iTrailTakeProfit * Point(),_Digits);
                 if(NormalizeDouble((OrderTakeProfit() - tp) < 0.0,_Digits))return;
                 tp = OrderTakeProfit();
                }else tp = 0.0;
              if(OrderProfit() + OrderSwap() + OrderCommission() > MarketInfo(Symbol(), MODE_TICKVALUE) * iTrailStart * OrderLots())return;
                {
                 if(NormalizeDouble((OrderProfit() - Ask) <= iTrailStart * Point(),_Digits))return;
                   {
                    if(OrderStopLoss() == 0.0 && NormalizeDouble((OrderStopLoss() - Ask) <= iTrailDist * Point(),_Digits))return;
                      {
                       if(iTrailStep > 0.0 && OrderStopLoss() == 0.0 && NormalizeDouble((OrderStopLoss() - Ask) - iTrailDist * Point(),_Digits) < iTrailStep * Point())return;
                         {
                          sl_lev = NormalizeDouble(Ask + iTrailDist * Point(),_Digits);
                          if(NormalizeDouble((sl_lev - Ask) > MarketInfo(Symbol(),MODE_STOPLEVEL) * Point,_Digits)) return;
                            {
                            if (!OrderModify(Forder,OrderOpenPrice(),OrderStopLoss() + iTrailStart * Point,OrderTakeProfit(),OrderExpiration()))
                            Print("Не удалось модифицировать стоплосс ордера №",OrderTicket(),". Ошибка: ",GetLastError());
}}}}}}}}}}

Come posso specificare al mio Expert Advisor per farlo funzionare?

  "\n",

  ); 
//xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx//
   double body = Close[1] - Open[1];
   if (CountTrades() == 0 && body > 0) BuyOpen();     // Если нет открытых и сигнал бай
   if (CountTrades() == 0 && body < 0) SellOpen();    // Если нет открытых и сигнал селл
   if (CountTrades(0) > 0 && body > 0) BuyOpen();     // Если есть открытые бай и сигнал бай
   if (CountTrades(1) > 0 && body < 0) SellOpen();    // Если есть открытые селл и сигнал селл
   Trail();
  }

Ho visto che lo specificano in questo modo, ma in qualche modo non funziona per me.

È un problema generale specificare l'ex perché la funzione funzioni, come devo fare?
