@Konstantin Nikitin È più facile per te, sei un esperto! Sto imparando!

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:

Come si legge questo? Se (Ordine non è selezionato) continuare;

If (Current Symbol non è uguale a Symbol) continua; Giusto? O come?

Operatore continua

@Konstantin Nikitin Ho capito, quindi: correggimi se c'è qualcosa!

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)


Ed ecco un'altra domanda: !OrderSelect - significa: nessun ordine o nessun ordine selezionato?

Rewerpool:

Capito, quindi: correggetemi se c'è qualcosa!

Se nessun ordine è selezionato, viene selezionato l'elemento successivo del ciclo

Inoltre, ecco una domanda: !OrderSelect - significa: Non un ordine o Non un ordine selezionato?

Operazioni ed espressioni e guardare le operazioni logiche lì

@Konstantin Nikitin Mettilo insieme così:

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();

            }

               }

}
Giusto?

aggiunto altri come questo:

Perché scriverlo in questo modo?

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

Se metti l'EA solo su un simbolo, ma funzionerà su tutti? E il mago vedrà il suo!

Completamente confuso!

Amici miei, chi sa come implementare: un EA può ottenere il valore assoluto di un indicatore, per esempio iStohastic(). Come posso dire se l'indicatore ha lasciato la zona di ipercomprato o ipervenduto?

Visivamente, come un indicatore stocastico con livelli 80 e 20.

Rewerpool: Bene, ecco, nessun errore.

Anche se hai esattamente la stessa logica quando modifichi EA e altri ordini. Perché esattamente bisogna distinguerli non è molto chiaro. Ma penso che il principio sia utile.
@Konstantin Nikitin USEK POWERFUL!!! GRAZIE per la ripartizione!!!
