mmmmm.... well personally i think it's written correctly - the only problem is the placement of the code snippets.... could you place it correctly? it's not clear to me how to do that.

Honestly, I don't know if you can describe one function within another, I've never come across it.
Don't confuse us darkies. At the level of this branch, it is enough to state that all user functions must be located outside the Start function.

Well I won't post it exactly, but as has already been written all the custom functions are beyond start.

At concept level

Start (){}

MACD{}

AnalyzeSignal(){}

Remove the description of custom functions to a separate file, make sure the rest of the program compiles without error bracketing messages and dock each function to the very end of the resulting code.

Thank you, it worked =) only the deals don't open, but that's a small thing =) couldn't have done it without you )

Dear Professionals, please give some advice. There are two moving averages with periods of 5 and 60. When crossing the fast MA over the slow one from the bottom upwards + filters, it opens a Buy trade. The problem is, how to make a trade open only once and when it closes, not open a new trade, even if there are suitable conditions to open, until there is a reverse crossover?

Hello.

Please help - please respond to my post on page 196. (question about int MAGIC;)

Thank you in advance.

Have you tried to make functions with parameters? So as not to use external global variables (everyone can call them by their own name)

set a flag to prohibit further opening and remove the flag when crossing back, a couple of bars can be delayed to prevent bouncing

I mean, like:

int OrdTicket_b(int MAGIC)
 {
  string SMB=Symbol();
  int OrdTicket;
  int i;
  for(i=0;i<OrdersTotal();i++)
   {
    if (OrderSelect(i,SELECT_BY_POS,MODE_TRADES) == true)
     {
      if(OrderSymbol()==SMB)
       {
        if(OrderMagicNumber()==MAGIC || OrderMagicNumber()==777)
         {
          if(OrderType()==OP_BUY || OrderType()==OP_SELL)
           {
            OrdTicket=OrderTicket();
           }  
         }  
       }          
     }
   }
  return(OrdTicket);
 }

???

...and the condition 

    if(OrderMagicNumber()==MAGIC || OrderMagicNumber()==777)

will be tracked correctly?

int OrdTicket_b(int lMAGIC)
 {
  string SMB=Symbol();
  int OrdTicket=0;
  int i;
  for(i=0;i<OrdersTotal();i++)
   {
    if (OrderSelect(i,SELECT_BY_POS,MODE_TRADES) == true)
     {
      if(OrderSymbol()==SMB)
       {
        if(OrderMagicNumber()==lMAGIC)
         {
          if(OrderType()==OP_BUY || OrderType()==OP_SELL)
           {
            OrdTicket=OrderTicket();
           }  
         }  
       }          
     }
   }
  return(OrdTicket);
 }
Like this, the variable OrdTicket should be assigned some default value. Otherwise there are no open positions and the function will return something
