Buonasera, ho notato che avete una grande libreria di codici già pronti. Forse avete del codice che determina il prezzo di apertura della barra precedente al momento di crearne una nuova? Saluti, Vladimir.

MrBrooklin:

Buonasera, ho notato che avete una ricca libreria di codici già pronti. Forse avete del codice che determina il prezzo di apertura della barra precedente al momento di crearne una nuova? Saluti, Vladimir.

Per esempio, il risultato del lavoro dell'Expert Advisor è il prezzo di una barra nella barra precedente.

Per esempio, da questa funzione - il risultato di Expert Advisor è peggiore

//+------------------------------------------------------------------+
//| Expert new tick handling function                                |
//+------------------------------------------------------------------+
void OnTick(void)
  {
   static datetime limit_time=0; // last trade processing time + timeout
//--- don't process if timeout
   if(TimeCurrent()>=limit_time)
     {
      //--- check for data
      if(Bars(Symbol(),Period())>2)
        {
         //--- change limit time by timeout in seconds if processed
         if(ExtExpert.Processing())
            limit_time=TimeCurrent()+ExtTimeOut;
        }
     }
  }
//+------------------------------------------------------------------+

Non capisco nemmeno cosa ho sbagliato qui, ma l'Expert Advisor dà un risultato migliore affidandosi al poking.

//+------------------------------------------------------------------+
//| Expert new tick handling function                                |

void OnTick(void)
  {

   limit_time=iTime(Symbol(),Period(),0);
   if(ExtTimeOut==limit_time)
      return;
//--- change limit time by timeout in seconds if processed
   if(ExtExpert.Processing())
      ExtTimeOut=limit_time;
  }

SanAlex :

Buona serata! Sono un autodidatta e prendo codici dagli esempi e ottengo il compito che mi sono prefissato con il metodo del poking scientifico.

Ad esempio, da questa funzione, il risultato dell'esperto è peggiore

e qui io stesso non capisco cosa ho imbrogliato - ma frugando, l'esperto mostra meglio il risultato.

Qui puoi verificare la differenza: sostituisci solo l'esempio sopra con il post

Tutti hanno la loro visione su come entrare e uscire le serrature. Advisors che ho incontrato sulla strada poi ha lavorato storto poi improvvisamente cancellato l'ordine, poi improvvisamente messo non è chiaro su quale principio.

vorrei scrivere me stesso, ma non può capire la programmazione . prendere il consiglio e ha deciso di aprire un ramo separato .

condizioni di lavoro per l'advisor

1.itself non commercio tutte le operazioni manualmente (acquisto e vendita)

2.Se l'affare si chiude in + allora l'ordine pendente viene cancellato.

nell'ordine pendente impostato prendere in min + (possibilità di regolare)

3. Quando l'ordine pendente scatta --- un altro ordine pendente è impostato a livello di 1 ordine (cioè totale dovrebbe essere uguale)

4. se il prezzo torna e forma un blocco --- allora tutti i takei vengono rimossi.

L'unica differenza è nella forma dell'accordo --- sembra l'apertura di una posizione chiusa nel grafico.5 Quando si apre qualsiasi parte del blocco, il pendente sul volume pari a questa parte è aperto. sul movimento dopo 15 -20 pips (regolare), cioè se apro buy, il pendente per buy e viceversa.

come tutti. sarebbe felice di sentire eventuali suggerimenti. se un tale miracolo appare alla luce sarà pubblicato per tutti coloro che sono interessati ad esso con codice open source. per mt4.

Buon giorno, cari programmatori.

Questa idea è rimasta nella mia testa per molto tempo. Ho provato a farlo manualmente, ma mi confondo. Sono sicuro che non c'è un algoritmo simile da nessuna parte nel trading (punto 3).

1. L'Expert Advisor apre ordini su ogni suddivisione di una candela High - Buy, Low - Sell.

2. Il TP è uguale a un ATR su un timeframe di lavoro.

3. Dopo la chiusura dell'ordine sul TP, l'Expert Advisor prende l'ordine più non redditizio e il 30% del TP dell'ordine chiuso (da stampare nelle variabili dell'Expert Advisor)

Traina il TP dell'ordine perdente nella zona negativa (seguendo il principio di prendere prima e rinunciare a una percentuale di profitto)

e così porta l'ordine in perdita alla sua chiusura con una perdita. Poi trova di nuovo l'ordine meno redditizio e continua a modificarlo finché non viene chiuso in perdita.

In ciascuna di queste serie, otterremo almeno il 60% di profitto tenendo conto dello swap e delle commissioni.
