UMA EA BASEADA EM FITAS B E LARGURA B, PRECISAM DE AJUDA URGENTE!!

 

Prezados todos,

Estou programando uma EA que funciona com Banda B e Largura B, Para a Largura B adicionei uma EA personalizada, Não há erros ao compilar,

Mas eu estou misturado com alguns detalhes na chamada do Indicador Personalizado.

Por isso, preciso da ajuda de alguns programadores para corrigi-lo, sempre agradecendo a quem me ajuda desta vez, bcoz eu fui parado agora,

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.

Prezados todos,

Estou programando uma EA que funciona com Banda B e Largura B, Para a Largura B adicionei uma EA personalizada, Não há erros ao compilar,

Mas eu estou misturado com alguns detalhes na chamada do Indicador Personalizado.

Por isso, preciso da ajuda de alguns programadores para corrigi-lo, sempre agradecendo a quem me ajuda desta vez, bcoz eu fui parado agora,

Agradecimentos Antecipados

Por favor, preste atenção na ordem dos parâmetros de entrada do iBand Widh :

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

De acordo com a ordem de entrada do indicador, ele deve :

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

você não precisa deste indicador personalizado.

você tem bbands, basta subtrair os envelopes das bbands.

surubabs:

Estou acrescentando esse Indicador personalizado, por favor, me multe o método correto de chamada deste indicador,

Obrigado por sua ajuda.

Como eu disse antes, você deve prestar atenção às ordens. Portanto, se parâmetro de entrada como este :

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

então para chamar indicadores, você deve escrever as mesmas ordens

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

Eu fiz isso como u advaiced, mas o problema que ainda estou enfrentando está no ontick(), quando eu copio os buffers, o indicador de largura tem apenas uma única linha, e no código indicador ele mostra como IndiBuffer,

Então qual buffer devo copiar do indicador de largura, se for como no código do indicador de largura .

//---- 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);

não posso utilizá-lo em condições de compra e venda,

por favor me aconselhe a programá-lo da maneira correta, tentei mais de dois dias inteiros sobre isto,

Por favor, ajude o senhor.

 

O que graziani lhe disse é que o uso do "i-BB_Width" é desnecessário. Este indicador calcula apenas a diferença entre as faixas superior e inferior. Portanto, você pode remover completamente este indicador de seu EA.

Depois disso, cabe a você verificar a lógica de seu algoritmo.

Ha ha ha boa solução, eu gosto disso :-)

Senhor, eu tenho um pedido,

posso diferenciar a largura em uma eA ? como width=Upband-Lowband/Baseline,

é possível?

Desculpe, mas não entendo sua pergunta.

Desculpe, mas não entendo sua pergunta.

Desculpe algum erro ortográfico,

quero a largura da faixa para isso, é necessário algum cálculo como

Largura=(banda superior-banda inferior)/banda de base

então é possível fazer este cálculo dentro da ea ?

como definir isto ? quando eu tento obter um erro,

Largura[]=(Banda superior[ ]-Banda inferior[ ])/Banda de base[ ],

por favor, advaice
