Chi altro può aiutare?).

Sembra che ti siano state date risposte ed esempi esaurienti, ma hai ancora bisogno di leggere l'aiuto per capire come vengono chiamate le funzioni e perché viene usato il modificatore statico.

Ecco un altro modo, forse ti sarà più facile da capire:

int N(bool reset=false) // если вызываем N() то возвращает следующее значение n++, при первом вызове n=0, но вернет 1, т.к. n=0, а затем n++, если нужно 0 то 
			// или  static int n=-1; или вызывайте сначала N(true)
  {                     // если вызываем N(true), то сбрасываем n=0 и возвращзаем 0
   static int n=0;
   if(reset) n=0; else n++;
   return n;
  }

Ecco un'altra variante, forse questo vi renderà più facile la comprensione:

Il primo esempio mostra una chiamata di funzione quando non viene presa nessuna posizione e il risultato restituito viene confrontato.

if( ((OpenB-Ask)/ma+TimeB/60) > N() )

Ecco perché probabilmente vale la pena di fare solo il ritorno senza azzerare e aggiungere. Che ho implementato in 2 varianti

scrivere un EA che quando clicco sul pulsante, crea un testo nel posto del grafico, come mostrato dal mouse. Ora il mio Expert Advisor crea solo il testo al posto del pulsante.

 

Ciao, come faccio a fare in modo che quando trascino manualmente un ordine pendente buystop, l'altro ordine pendente sellstop si sposti con esso?

Come posso legare uno all'altro, in modo che quando ne muovo uno, li muova entrambi contemporaneamente?

  


Здравствуйте. У меня алгоритм такой 
//----------------------------------------------------------------------------
if (CountBuy() == 0)
{

BuySignal = h1; tttp=1; 
if (BuySignal > 0 && tttp==1 && h2>0)
{
CloseSell();
ticket = OrderSend(Symbol(), OP_BUY, Lots, Ask, Slippage, 0, 0, comment, Magic, 0, Blue);

if (ticket > 0)
{

if (OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES))
{

SL = NormalizeDouble(Ask-StopLoss*Point, Digits);

TP = NormalizeDouble(Ask+TakeProfit*Point, Digits);

res = OrderModify(OrderTicket(), OrderOpenPrice(), SL, TP, 0);
if (!res)

Print("Ошибка модификации ордера на покупку, ASK=" + DoubleToStr(Ask) + ", SL=" + DoubleToStr(SL) + ", TP=" + DoubleToStr(TP)); 
}
}
}
}
if (CountSell() == 0)
{
SellSignal= l1; tttp=-1;
if (SellSignal > 0 && tttp==-1 && l2>0)
{
CloseBuy();
ticket = OrderSend(Symbol(), OP_SELL, Lots, Bid, Slippage, 0, 0, comment, Magic, 0, Red);
if (ticket > 0)
{
if (OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES))
{
SL = NormalizeDouble(Bid+StopLoss*Point, Digits);
TP = NormalizeDouble(Bid-TakeProfit*Point, Digits);
res = OrderModify(OrderTicket(), OrderOpenPrice(), SL, TP, 0);
if (!res)
Print("Ошибка модификации ордера на продажу, BID=" + DoubleToStr(Bid) + ", SL=" + DoubleToStr(SL) + ", TP=" + DoubleToStr(TP)); 
}
}
}
}
} 
//------------------------------------------------------------------------------------------
Пытаюсь сделать, чтоб условия на открытие ордера проверялось бы через какое-то кол-во баров, а так сразу открывается другой ордер

Perché lo spam?

Quello che hai scritto in diversi thread? Posso tirarlo giù.
 
Ihor Herasko:

Scrivete i vostri zecchini e metteteli nel tester di strategia.

Saluti. Puoi dirmi qual è il problema e come risolverlo?

Ho cambiato alcuni candelieri nella storia per i test, per il 1°, 2°, 3° e 6°.

Durante il test, il secondo viene elaborato, il terzo viene disegnato (senza elaborazione), e si ferma dando un errore fermato a causa di Stop Out



 

Buon pomeriggio

Ho una situazione molto semplice ma ho problemi a risolverla.

Per favore, ditemi cosa sto sbagliando:

problema: non riesco a legare l'indicatore personalizzato(i-DRP...) all'Expert Advisor (DR Test) tramite iCustom

grazie in anticipo
