Couldn't find it either. It doesn't matter.

If you work at opening prices, it's enough to check at the opening of a new bar.

int start(){
  if (! NevBar()) return(0);
  
  //.......
  
  return(0);
}

bool NevBar(){
  static int prevtime=0;
  if ( prevtime==Time[0]) return(false);
  prevtime=Time[0];
  return(true);
}

That's about right. And if the opening is possible at other prices. We should use other mechanisms.

If only one position can be opened by one symbol and timeframe, we must control the number of open positions.

int CountOrder[6];

// Функция формирует массив с количеством открытых позиций по каждому виду ордеров.
//===============================================================================
int Order_Count_Calculate(string _Symbol, int _Magic, int _OP=-1){
   ArrayInitialize( Order_Count,0);
   for (int i = OrdersTotal() - 1;  i >= 0;  i--) {
      if (!OrderSelect( i, SELECT_BY_POS, MODE_TRADES))   continue;
      if (OrderSymbol() != _Symbol)                     continue;
      if (OrderMagicNumber() != _Magic)                   continue;
      Order_Count[OrderType()]++;
   }
   if (_OP>=0) return( Order_Count[_OP]);
   return(0);
}

Now, by checking the values of the necessary array elements, we know how many positions of this type are opened.

For example (example of setting a buy stop) :

(it is not at all necessary for the set price to be in the quote stream in order to set a pending order.

You can go with the current price or with any price, as long as you adhere to the stop level from CURRENT PRICE TO THE STOP PRICE)

( 'EURUSD - Trends, Forecasts & Consequences' )

Instead of

double priceBUY=..... ....

enter your formula

EH...thanks so much especially for the attached code! Just what the doctor ordered! ))))

Vinin! Thank you!

I have this in the code, but I don't understand this array, how will it detect if there was an order on this bar and it closed, and we will wait for a new bar?

How do I explain? I might have misspoken or misunderstood the function....

1) If we open an order on the zero bar and it is already closed, then we do not open another order on this bar even if there is a signal to open it because we have already had a trade on this bar and it is already closed.

On each bar it is allowed to open only one deal, if there was a deal on this bar, we do not open the order, how to do?

Help people.....))) I'm already having a meltdown \\\\\\\\>>>>

1) double NormalizeDouble( double value, int digits), and you have (vinn/2, 0.1)

2) OrderSend(Symbol(), OP_BUY, GetSizeLot(), Ask, 3, Ask - StopLoss*Point,NO TAKE_profit, "AlanMod expert", 16384, 0, Green);

 
Thank you, I was just ahead of you)
 

how do I name the buffers in the custom indicators?
