skyjet:
Esta não é uma função aninhada, mas faz parte da amostra básica MACD EA. Estou tentando adicionar um lote calculado. Função principal e única de início()

É preciso, então, olhar o código inteiro. O que você mostrou é a função
 
Ali :) Eu simplesmente não sei como caber no cálculo do lote mencionado acima.

É algo assim
 
Vinin:
É mais ou menos assim.
Obrigado por sua ajuda!

Obrigado por sua ajuda!

Somente a função de cálculo do lote deve ser universal
 

Olá.

Eu sou um principiante neste negócio. Por isso estou pedindo sua ajuda.


Aqui está um pedaço de código:

int start()
  {
  
    
   if(IsTesting())return;
 
      
    if (AccountBalance() < 111 ){
      Alert("Erorr Balance");
      return; 
      
    if (AccountNumber() != 11111){
      Alert("Error AccountNumber");
      return;}
      
   }
  

Quero verificar primeiro o saldo do montante se for inferior a 111 e depois alertar e devolver, se for superior ao número da conta, se a conta estiver correta, então negociar se não alertar e devolver...

Mas por alguma razão, isso só é feito individualmente se eu remover AccountBalance ou AccountNumber.

Provavelmente uma nova pergunta, mas o que eu perdi?

obrigado

Você já tentou colchetes (colchetes em forma de parênteses)?

int start()
  {
  
    
   if(IsTesting())return;
 
      
   if (AccountBalance() < 111 )
   {
       Alert("Erorr Balance");
       return(0); 
   }  
   if (AccountNumber() != 11111)
   {
       Alert("Error AccountNumber");
       return(0);
   }
   return(0);
}

Havia parênteses suficientes, mas nos lugares errados

 

Eu o ajustei com sua ajuda, mas ele não consegue compilar, então aqui está uma captura de tela, deve ser um suporte extra ou .... :(

 
Encontre um editor de texto que tenha uma função de rastreamento de parênteses.
 
Vinin:

E se também houvesse posições em aberto em outros instrumentos, ou outros EAs? Pense no que você está escrevendo.
Infelizmente, a descrição da condição não pretende ser completa e não revela totalmente o conceito da "40ª ordem". Então seria muito mais fácil manter o número de ordens abertas na EA em uma variável, ao invés de usar as funções padrão. As ordens pendentes são uma questão à parte nesta situação.
