UN EA BASATO SU BANDE B E LARGHEZZA B, BISOGNO DI AIUTO URGENTE!

surubabs Suresh Kakkattil  

Cari tutti,

Sto programmando un ea che funziona con B Band e B Width, per la B Width ho aggiunto un EA personalizzato, non c'è nessun errore quando compilo,

Ma sono sicuro che ci sono alcuni problemi nella chiamata dell'indicatore personalizzato.

così ho bisogno dell'aiuto di alcuni programmatori per correggerlo, sono sempre grato a chi mi aiuta questa volta, perché ora sono stato fermato,

I will not list all of the new possibilities and features of the new terminal and language. They are numerous, and some novelties are worth the discussion in a separate article. Also there is no code here, written with object-oriented programming, it is a too serous topic to be simply mentioned in a context as additional advantages for developers. In this article we will consider the indicators, their structure, drawing, types and their programming details, as compared to MQL4. I hope that this article will be useful both for beginners and experienced developers, maybe some of them will find something new.

Si prega di prestare attenzione all'ordine del parametro di input di iBand Widh:

BB_Handle=iCustom(NULL,PERIOD_M1,"i-BB-Width",ibands_period,ibands_shift,ideviation,PRICE_CLOSE);

Secondo l'ordine di ingresso dell'indicatore, dovrebbe:

BB_Handle=iCustom(NULL,PERIOD_M1,"i-BB-Width",ibands_period,ideviation,iapplied_price,ibands_shift);
graziani  

non hai bisogno di questo indicatore personalizzato.

Se hai delle bande, basta sottrarre gli inviluppi delle bande.

Sto aggiungendo quell'indicatore personalizzato, per favore, mi faccia sapere il metodo di chiamata corretto di questo indicatore,

Grazie per il tuo aiuto.

Come ho detto prima dovresti prestare attenzione agli ordini. Quindi se il parametro di input come questo:

input uint bands_period=20; //smoothing depth                    
input double deviation=2.0; //deviation
input ENUM_APPLIED_PRICE  applied_price=PRICE_CLOSE; //type of price or handle
input int Shift=0; //horizontal shift of the indicator in bar

allora per chiamare gli indicatori dovresti scrivere gli stessi ordini

BB_Handle=iCustom(NULL,PERIOD_M1,"i-BB-Width",bands_period,deviation,applied_price,Shift);

Ho fatto come mi hai consigliato, ma il problema che sto ancora affrontando è in ontick(), quando copio i buffer, l'indicatore di larghezza ha solo una singola linea, e nel codice dell'indicatore viene mostrato come IndiBuffer,

Allora quale buffer dovrei copiare dall'indicatore di larghezza, se è come nel codice dell'indicatore di larghezza.

//---- copy newly appeared data into the arrays  
   if(CopyBuffer(BB_Handle,UPPER_BAND,0,to_copy,UpBB)<=0) return(RESET);
   if(CopyBuffer(BB_Handle,LOWER_BAND,0,to_copy,DnBB)<=0) return(RESET);

Non posso usarlo in condizioni di acquisto e vendita,

vi prego di consigliarmi di programmarlo nel modo corretto, ho provato più di due giorni interi su questo,

Per favore aiutatemi, signore.

Quello che ti ha detto graziani è che l'uso di "i-BB_Width" non è necessario. Questo indicatore calcola solo la differenza tra le bande superiore e inferiore. Quindi puoi rimuovere completamente questo indicatore dal tuo EA.

Dopo di che sta a te controllare la logica del tuo algoritmo.

Ha ha bella soluzione, mi piace :-)

Signore, ho un dubbio,

posso dividere la larghezza in un EA, come width=Upband-Lowband/Baseline,

è possibile?

Scusa ma non capisco la tua domanda.

Scusa qualche errore di ortografia,

Voglio la larghezza della banda per questo ha bisogno di qualche calcolo come

Larghezza=(banda superiore-bassa)/banda base

è possibile fare questo calcolo all'interno dell'ea?

Come definirlo? Quando ho provato ho ottenuto un errore,

Width[]=(Upperband[ ]-Lowerband[ ])/Baseband[ ],

per favore consigliatemi
