Please help a beginner. How to write such a piece of code:

Check market orders and if there are no market orders for our financial instrument, we buy it?

It's not working!!! Help... Maybe someone has a ready-made piece of code? 

//---- Проверка отрытых ордеров
void CheckOpenedOrders()
 {
  my_OrderBuy=-1;
  my_OrderSell=-1;
  for (int j = 0; j < OrdersTotal(); j++)
   {
    OrderSelect(j, SELECT_BY_POS, MODE_TRADES);
    if (OrderSymbol() == Symbol())
     {
      if (OrderType() == OP_BUY)
       {
        my_OrderBuy = OrderTicket();
       }
       else DoTrade(1);
      if (OrderType() == OP_SELL)
       {
        my_OrderSell = OrderTicket();
       }
       else DoTrade(2);
     }
   }
 }
//----

//----
void DoTrade(int workmode)
 {
  switch (workmode)
   {
    case 1:
     {
      my_OrderBuy=OrderSend(Symbol(),OP_BUY,lots,NormalizeDouble(Ask,Digits),SlipPage,
                  0,0,NULL,0,0,Red);
     }
    break;
    
    case 2:
     {
      my_OrderSell=OrderSend(Symbol(),OP_SELL,lots,NormalizeDouble(Bid,Digits),SlipPage,
                   0,0,NULL,0,0,Blue);
     }
    break;
   }
  return;
 }

Can you give it all in working form, i.e. with a start function and a description? It's not very clear. Thanks in advance!

Question. I would like to know when to open orders?

We check the market orders and if there are no market buy orders for our financial instrument, we make a buy? This is the kind of area we need...

So we only open long positions?

Yes, if there are no market buy orders for our financial instrument, then we buy!

icas, don't embarrass yourself in front of newcomers, fix your code to the right one.

Where? I don't see it.

on the first non-buy order you will flood the account with buy orders.
