Help me solve a problem

I sample all the closed items

for (int i=0; i<OrdersHistoryTotal(); i++)// For all orders
if(OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)==true)

then filter by magic number

if (OrderMagicNumber()==12)

filter satisfies 3 positions, but I need only the last closed one

can't figure out how to leave only the last one?

Thanks

Again, very much needed.

Help me solve the problem.

I am selecting by all closed positions

for (int i=0; i<OrdersHistoryTotal(); i++)// on all orders of the terminal
if(OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)==true)

afterwards filter by magic number

if (OrderMagicNumber()==12)

the filter matches 3 positions but I need only the last closed one

Can't figure out how to leave only the last one?

Thanks

Guys, here's a question, an EA tries to open an order, but the price changes and displays an error wrong price, how can I bypass it, so it tries to buy until it buys?

void CLOSEORDER(string ord)
{
   for (int i=0; i<OrdersTotal(); i++)
   {                                               
      if (OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==true)
      {
         if (OrderSymbol()!=Symbol()) continue;
         if (OrderType()==OP_BUY && ord=="Buy")
            OrderClose(OrderTicket(),OrderLots(),Bid,30,CLR_NONE);// Закрываем Buy
         if (OrderType()==OP_SELL && ord=="Sell")
            OrderClose(OrderTicket(),OrderLots(),Ask,30,CLR_NONE);// Закрываем Sell
      }   
   }
}
//--------------------------------------------------------------------
void OPENORDER(string ord)
{
   int error;
   if (ord=="Buy" ) error=OrderSend(Symbol(),OP_BUY, LOT,Ask,20,SL,TP,"", 1,3);
   if (ord=="Sell") error=OrderSend(Symbol(),OP_SELL,LOT,Bid,20,SL,TP,"",-1,3);
   if (error==-1) //неудачная покупка OK
   {  
      ShowERROR(error,0,0);
   }

It used to be.

Bid,3,CLR_NONE

I added 30 because I have a 5 sign but it's useless.

Help me solve the problem.

I'm sampling all the closed items.

Start at the end, then the first matching one is the one.

for (int i=OrdersHistoryTotal()-1;i>=0; i--)//
if(OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)==true)

Craft:

There is still one more annoyance, there are sections where there is only a closing of a position and not a reversal, although the conditions for a stop and opening a new position are the same.

These situations can occur because the buy and sell conditions in the Expert Advisor are not mutually exclusive. Try to trace the values of the required variables in the tester according to

if(Time[0]=='время_нужного_бара') //чтоб не засорять логи берем на конкретном баре - посмотрите на картинке, где именно ошибка
{
   Print("переменная=", значение);
}

Do an order while(true), check for 135 errors and then RefreshRates(). Look, there are scripts with examples in the package with the terminal, everything is explained there.

OK, in which part of the code should this be inserted, how practically applied?
