Introduzione

Un Expert Advisor o un indicatore che non utilizza indicatori tecnici standard nel suo codice è raro. Sono popolari sia per i principianti che per gli sviluppatori esperti di strategie di trading. Non è difficile capire i dettagli per creare degli indicatori; lo scopo di questo articolo è quello di aiutare in questa operazione. Analizzeremo l'uso delle funzioni per lavorare con indicatori tecnicistandard integrati.

Fondamenti dell'Utilizzo delle Funzioni degli Indicatori Tecnici Standard

Quando viene chiamata, ogni funzione di un indicatore tecnico crea un handle dell'oggetto creato (istanza dell'indicatore) con parametri di input specificati. Lo scopo dell'handle è assegnargli questo oggetto. È sufficiente ottenere i dati dal buffer dell'indicatore e utilizzarli nei propri calcoli. Consideriamo un esempio:

double      MA[];                // array for the indicator iMA
int         MA_handle;           // handle of the indicator iMA
//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
   //--- creation of the indicator iMA
   MA_handle=iMA(NULL,0,21,0,MODE_EMA,PRICE_CLOSE);
   return(0);
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
   //--- filling an array MA[] with current values of iMA
   //--- Copying 100 elements
   CopyBuffer(MA_handle,0,0,100,MA);
   //--- set indexing of elements as series, as in MQL4
   ArraySetAsSeries(MA,true);  
   //--- here you can use the data of MA[] as you wish, for example: 
   if(MA[0]>MA[1])
      {
      //--- some operations
      }
   }

Come vediamo, tutto è abbastanza semplice. Questo esempio mostra come utilizzare l'indicatore iMA - il più popolare tra i trader.

L’handle dell'indicatore deve essere creato all'interno della funzione OnInit()

  1. "Imposta l'indicizzazione degli elementi come serie, come in MQL4"- cosa significa? Nel nostro esempio abbiamo usato gli elementi di indicizzazione come timeseries. In altre parole, la barra corrente (che non si è ancora formata) ha sempre indice [0], la precedente (già formata) ha indice [1], ecc.
  2. Perché impostiamo l'indicizzazione? La abbiamo usato per la comodità e l'implementazione ottimale dell'algoritmo. Il linguaggio MQL5 consente di utilizzare la comoda indicizzazione per il programmatore.
  3. Perché è meglio creare un indicatore all'interno della funzione OnInit()? Naturalmente, può essere creato ovunque nel programma, perché non esiste alcun divieto esplicito. Tuttavia, c'è un forte argomento a favore del modo proposto: la funzione OnInit() viene chiamata una volta all'avvio di un Expert Advisor ed è abbastanza sufficiente per eseguire l'inizializzazione degli indicatori che non cambia i suoi parametri durante l'esecuzione. Nel caso in cui cambino i loro parametri di input, è possibile inizializzarli nuovamente all'interno di un'altra funzione, ad esempio nella funzione OnTick().

Lezioni di programmazione

Quasi tutti gli Expert Advisor sono progettati per eseguire operazioni di trading non solo sulla demo, ma anche su un account reale. Se vuoi dormire sonni tranquilli quando esegue operazioni di trading, dovresti prevedere tutti i possibili risultati del suo trade. Anche gli sviluppatori altamente qualificati di sistemi di trading automatizzati spesso commettono errori fastidiosi. E il prezzo di tale errore può essere molto alto!

Ad esempio, ecco una storia accaduta all'Automated Trading Championship 2008. Un Expert Advisor di uno dei partecipanti dovrebbe aumentare il suo deposito ad un certo livello e dormire. E' stato fatto. L'autore e tutti coloro che stavano guardando il lavoro dell'Expert Advisor sono rimasti sorpresi, quando si è svegliato e ha iniziato a fare di nuovo trading, perdendo i soldi guadagnati.

Naturalmente, tu non vuoi commettere errori simili quando il robot va fuori controllo. Quindi, consideriamo le "barriere coralline" che possono essere catturate durante l'utilizzo degli indicatori tecnici standard:

  1. Il puntatore dell’oggetto viene creato nel blocco di inizializzazione. E se non ci fosse riuscito? In questo caso, otterremo un riferimento vuoto. Pertanto, usiamo la possibilità di verificarne la validità che è stata fornita dagli sviluppatori MQL5. Se il puntatore non è stato creato, il valore dell’handle, restituito dalla funzione, sarà uguale alla costante standard INVALID_HANDLE = -1.
  2. Quando otteniamo i dati dall'indicatore, stiamo copiando i suoi valori nel buffer dell'indicatore e li utilizziamo nei nostri calcoli. Cosa succede se non ci è riuscito? Se la copia non è riuscita, un sistema di trading può generare segnali di trading errati. Per questi casi, gli sviluppatori di MQL5 hanno fornito la possibilità di controllare immediatamente il numero di elementi copiati. Il numero di elementi copiati in caso di errore sarà pari a -1.

Ora consideriamo come può essere codificato:

//---- arrays for indicators
double      MA[];                // array for the indicator iMA
//---- handles for indicators
int         MA_handle;           // handle of the indicator iMA
//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
   //--- creation of the indicator iMA
   MA_handle=iMA(NULL,0,21,0,MODE_EMA,PRICE_CLOSE);
  //--- report if there was an error in object creation
   if(MA_handle<0)
      {
      Print("The creation of iMA has failed: MA_handle=",INVALID_HANDLE);
      Print("Runtime error = ",GetLastError());
      //--- forced program termination
      return(-1);
      }
   return(0);
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
    //--- filling an array MA[] with current values of iMA
    //--- 100 elements should be written to the array
    //--- if there was an error, we terminate the execution of program
   if(CopyBuffer(MA_handle,0,0,100,MA)<=0) return;
   //--- set indexation of array MA[] as timeseries
   ArraySetAsSeries(MA,true);
   //--- here you can use the data of MA[] as you wish
   if(MA[0]>MA[1])
      {
      //--- some operations
      }
  }

Si noti che solo un piccolo cambiamento nel codice ha aumentato la sua sicurezza e affidabilità. Ma non è tutto. Ora la procedura di copia dei valori dell'indicatore nell'array può essere migliorata. È necessario utilizzare la funzione che è stata scritta:

//+------------------------------------------------------------------------------+
//| The function copies the values of the indicator,the elements                 |
//| will be indexed depending on the value of the input parameter asSeries       |
//+------------------------------------------------------------------------------+
bool CopyBufferAsSeries(
                        int handle,      // indicator's handle
                        int bufer,       // buffer index
                        int start,       // start index
                        int number,      // number of elements to copy
                        bool asSeries,   // if it's true, the elements will be indexed as series
                        double &M[]      // target array
                        )
  {
//--- filling the array M with current values of the indicator
   if(CopyBuffer(handle,bufer,start,number,M)<=0) return(false);
//--- the elements will be indexed as follows:
//--- if asSeries=true, it will be indexed as timeseries
//--- if asSeries=false, it will be indexed as default
   ArraySetAsSeries(M,asSeries);
//---
   return(true);
  }

La funzione CopyBufferAsSeries si trova nel file GetIndicatorBuffers.mqh, allegato all'articolo. Per il suo utilizzo, dobbiamo aggiungere la direttiva include nel nostro codice. E' necessario copiarlo nella cartella.. \ MQL5\Include\. Il codice finale che chiama l'indicatore iMA e copia i dati dal buffer dell'indicatore nell’array corrispondente è il seguente:

#include <GetIndicatorBuffers.mqh>
//---- arrays for indicators
double      MA[];                // array for the indicator iMA
//---- handles for indicators
int         MA_handle;           // handle for the indicator iMA
//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
//--- creation of the indicator iMA
   MA_handle=iMA(NULL,0,21,0,MODE_EMA,PRICE_CLOSE);
//--- report if there was an error in object creation
   if(MA_handle<0)
     {
      Print("The creation of iMA has failed: Runtime error =",GetLastError());
      //--- forced program termination
      return(-1);
     }
   return(0);
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
//--- filling an array MA[] with current values of iMA
//--- set indexation of array MA[] as timeseries
//--- return if there was an error
   if(!CopyBufferAsSeries(MA_handle,0,0,100,true,MA)) return;
//--- here you can use the data of MA[] as you wish, for example: 
   if(MA[0]>MA[1])
     {
      //--- some operations
     }
  }


Caratteristiche degli Indicatori Multi-Buffer

Ad esempio, consideriamo l'indicatore iAlligator, che ha 3 buffer indicatori:

  • 0 buffer - GATORJAW_LINE
  • 1° buffer - GATORTEETH_LINE
  • 2° buffer - GATORLIPS_LINE

Per eseguire i dati ricevuti dai buffer di questi indicatori utilizzando una chiamata, utilizzeremo la seguente funzione, che può essere trovata nel file, inclusa nell'articolo

//+------------------------------------------------------------------------------+
//| The function copies the values of the indicator Alligator to three arrays:   |
//| Jaws[], Teeth[], Lips[] (with elements indexed as timeaseries).              |
//+------------------------------------------------------------------------------+
bool GetAlligatorBuffers(int Alligator_handle,
                         int start,
                         int number,
                         double &Jaws[],
                         double &Teeth[],
                         double &Lips[],
                         bool asSeries=true  // (elements indexed as timeaseries)
                         )
  {
//--- filling an array Jaws with current values of GATORJAW_LINE
   if(!CopyBufferAsSeries(Alligator_handle,0,start,number,asSeries,Jaws)) return(false);
//--- filling an array Teeth with current values of GATORTEETH_LINE
   if(!CopyBufferAsSeries(Alligator_handle,1,start,number,asSeries,Teeth)) return(false);
//--- filling an array Lisp with current values of GATORLIPS_LINE
   if(!CopyBufferAsSeries(Alligator_handle,2,start,number,asSeries,Lips)) return(false);
//---
   return(true);
  }

che può essere utilizzato come segue:

#include <GetIndicatorBuffers.mqh>
//---- indicator buffers
double      Jaws[];   // array for GATORJAW_LINE of iAlligator
double      Teeth[];  // array for GATORTEETH_LINE of iAlligator
double      Lips[];   // array for GATORLIPS_LINE of iAlligator
//---- handles for indicators
int         Alligator_handle;           // handle of the indicator iAlligator
//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
//--- creation of the indicator iAlligator
   Alligator_handle=iAlligator(NULL,0,13,8,8,5,5,3,MODE_EMA,PRICE_MEDIAN);
//--- report if there was an error in object creation
   if(Alligator_handle<0)
     {
      Print("The creation of iAlligator has failed: Runtime error =",GetLastError());
      //--- forced program termination
      return(-1);
     }
   return(0);
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
//--- set indexation of arrays as timeseries
//--- fill arrays with current values of Alligator
//--- return if there was an error
   if(!GetAlligatorBuffers(Alligator_handle,0,100,Jaws,Teeth,Lips,true)) return;
  }

Conclusione

  1. L'uso di indicatori tecnici standard negli Expert Advisors in MQL5 è semplice, come lo è nella versione precedente.
  2. Utilizza solo metodi di programmazione sicuri nei tuoi Expert Advisor : analizza ed escludi tutti i possibili errori. Il prezzo degli errori è troppo alto: è il tuo deposito!

Introduzione a MQL5: Come scrivere un semplice Expert Advisor e un Indicatore Personalizzato Introduzione a MQL5: Come scrivere un semplice Expert Advisor e un Indicatore Personalizzato
Il Linguaggio di Programmazione MetaQuotes 5 (MQL5), incluso nel Client Terminal MetaTrader 5, ha molte nuove possibilità e prestazioni più elevate rispetto a MQL4. Questo articolo ti aiuterà a familiarizzare con questo nuovo linguaggio di programmazione. I semplici esempi di come scrivere un Expert Advisor e un Indicatore Personalizzato vengono presentati in questo articolo. Considereremo anche alcuni dettagli del linguaggio MQL5, necessari per comprendere questi esempi.
L'Ordine di Creazione e Distruzione dell'oggetto in MQL5 L'Ordine di Creazione e Distruzione dell'oggetto in MQL5
Ogni oggetto, sia esso un oggetto personalizzato, un array dinamico o un array di oggetti, viene creato ed eliminato nel programma MQL5 nel suo modo particolare. Spesso, alcuni oggetti fanno parte di altri oggetti e l'ordine di eliminazione dell'oggetto durante la reinizializzazione diventa particolarmente importante. Questo articolo fornisce alcuni esempi che illustrano i meccanismi di utilizzo degli oggetti.
Usare i Puntatori di Oggetti in MQL5 Usare i Puntatori di Oggetti in MQL5
Di default, tutti gli oggetti in MQL5 vengono passati per riferimento, ma esiste la possibilità di utilizzare i puntatori agli oggetti. Tuttavia è necessario eseguire il controllo del puntatore, poiché l'oggetto potrebbe non essere inizializzato. In questo caso, il programma MQL5 verrà terminato con errore critico e scaricato. Gli oggetti, creati automaticamente, non causano tale errore, quindi in questo senso sono abbastanza sicuri. In questo articolo, cercheremo di comprendere la differenza tra il riferimento all'oggetto e il puntatore all'oggetto e considereremo come scrivere il codice sicuro, che utilizzi i puntatori.
Limitazioni e Verifiche sugli Expert Advisors Limitazioni e Verifiche sugli Expert Advisors
È consentito fare trading con questo simbolo lunedì? Ci sono abbastanza soldi per aprire una posizione? Quanto è grande la perdita se si attiva lo Stop Loss? Come limitare il numero di ordini in sospeso? L'operazione commerciale è stata eseguita nella barra corrente o in quella precedente? Se un robot di trading non può eseguire questo tipo di verifiche, qualsiasi strategia di trading può rivelarsi perdente. Questo articolo mostra gli esempi di verifiche utili su qualsiasi Expert Advisor.
