Good evening! Could you please tell me if I have implemented correctly the start() function of an indicator in an EA? The compilation does not agree!


Well, so many sevens just can't be wrong, it's a JACK-POT!!!

But seriously, the description of the problem is obviously incomplete, you should go to the Telepath Club. Or describe in more detail what is wrong, a list of compiler errors, for example.

At first I got this error:

'\end_of_program' - ending bracket '}' expected C:\Program Files\Alpari \experts\xxx.mq4 (305, 1)

Of course I added a parenthesis, after that :

'Ind_Start' - function is not defined C:\Program Files\ Alpari \experts\xxx.mq4 (86, 1)

'{' - semicolon expected C:\Program Files\ Alpari \experts\xxx.mq4 (87, 3)

int start()
{

int varGet_Indicator_start = funcGet_Indicator_start();

return();
  
}


int funcGet_Indicator_start()

{
77777777777777777777777777777
77777777777777777777777777
777777777777777777777777777777
и чтоб возвращало int!!!
}

it should be so agree

 

Help, the indicator doesn't work. What did I write wrong?

//-----
  int i,limit;
  int counted_bars=IndicatorCounted();
  if (counted_bars>0) counted_bars--; 
  limit=Bars-counted_bars;
//-----
   for(i=limit; i>=0; i--)
  {SMMA[i]=iMA(NULL,0,TrixPeriod,0,MODE_SMMA,PRICE_CLOSE,i);}
//-----
  for(i=limit; i>=0; i--)
  {EMAOnArray[i]=iMAOnArray(SMMA,0,TrixPeriod,0,MODE_EMA,i);}
//-----
  for(i=limit; i>=0; i--)
  {SMMAOnArray[i]=iMAOnArray(EMAOnArray,0,TrixPeriod,0,MODE_SMMA,i);}
//-----
  for(i=limit; i>=0; i--)
  {Trix[i]=(SMMAOnArray[i]-SMMAOnArray[i+1])/SMMAOnArray[i];}
//-----
  for(i=limit; i>=0; i--)
  {Signal[i]=iMAOnArray(Trix,0,SignalPeriod,0,MODE_EMA,i);}       
//-----
  for(i=limit; i>=0; i--)
  {Histogram[i]=Trix[i]-Signal[i];}
//-----
 

Please advise me!

Suppose I have several open positions in the terminal and I need to know the opening price of one of the orders, say BUY, I also know the magic of each order?

How do I do that?

Good afternoon!

Could you please tell me how to write:

if ((b1!=0) && (b2==0))

openBuy(Lot,Magic);

if ((b1==0) && (b2!=0))

closeAll();

if ((s1!=0) && (s2==0))

openSell(Lot,Magic);

if ((s1==0) && (s2!=0))

closeAll();

but orders won't open so help me to find the reason
