ma devi (confronto)


Prendete il codice di qualsiasi indicatore OEM e vedete come è formattato il codice

Non vedo alcuna differenza. per esempio, è una disciplina standard. è solo la complessità che la rende tale. tuttavia, oltre alla parentesi stessa può essere una questione di ";" per esempio...

KONDOR:
fare più attenzione alle parentesi ))))
Simbolo()

È questo che intende, per esempio?

se(OrderSymbol()==Symbol())

L'errore rimane.

 

è anche se? o cosa?

Lo rifarò allora...

dovrebbe essere così: if(OrderSymbol()==Symbol() ?

tutti i simboli sono definiti.

rimosso la parentesi - non è cambiato nulla.

 
KONDOR:
la penultima parentesi non è necessaria
tutti uguali =(
 
frxmax:

dov'è l'errore a, in termini di parentesi tutto sembra essere dritto?

Grazie mille per il vostro aiuto. KONDOR
 

L'unico problema è che i risultati non sono così buoni.

Aiutami a capire come fare in modo che solo un ordine sia stato aperto nella direzione del segnale precedentemente ricevuto. chiuderlo quando uno degli indicatori mostrerà un segnale inverso. e tutto tenendo conto della coppia di valute

 
controllare la funzione NumberOfBarOpenLastPos(), controlla il numero della barra in cui l'ordine è aperto
 

Preferisco che sia così: (per esempio sul grafico dell'eurodollaro, c'è un segnale di acquisto)

se totale>1

se coppia di valute = eurodollaro

se l'ordine è di vendere

chiudere l'ordine

aprire un ordine di acquisto


La vista generale dovrebbe assomigliare a questa

se (segnale di acquisto)

se totale==0

comprare

altrimenti (totale >1)

controlla su quale coppia di valute ha aperto delle offerte

se il nostro

se in vendita

chiuderlo e tornare a comprare

oppure (totale = 0, aprire un acquisto) ....
