It's nopt an open order, it's a close.

Fix your code.

Using OrdersTotal directly and/or no Magic number filtering on your OrderSelect loop means your code is incompatible with every EA (including itself on other charts and manual trading.)

ok  unique magic number for each chart .  thank you  :)

frank75: is not correct ?

1. When you post code please use the CODE button (Alt-S)! (For large amounts of code, attach it.) Please edit your post.

2. 'no Magic number filtering on your OrderSelect loop means your code is incompatible with every other EA (and manual trading.)"

3. In the presence of multiple orders (one EA multiple charts, multiple EAs, manual trading,) while you are waiting for the current operation (closing, deleting, modifying) to complete, any number of other operations on other orders could have concurrently happened and changed the position indexing:
   1. For non-FIFO (US brokers,) (or the EA only opens one order per symbol,) you can simply count down in a position loop, and you won't miss orders. Get in the habit of always counting down.

      For FIFO (US brokers,) and you (potentially) process multiple orders per symbol, you must count up and on a successful operation, reprocess all positions (set index to -1 before continuing.)
   2. and check OrderSelect in case earlier positions were deleted.

   3. and if you (potentially) process multiple orders, must call RefreshRates() after server calls if you want to use the Predefined Variables (Bid/Ask) or OrderClosePrice() instead, on the next order/server call.

4. Check your return codes for errors, report them and you would know why. Don't just silence the compiler, it is trying to help you.

   Only those functions that return a value (e.g. iClose, MarketInfo, etc.) must you call ResetLastError before in order to check after.

i try this buot not work correctly

for( int i = 0 ; i < OrdersTotal() ; i++ )
           {
            OrderSelect( i, SELECT_BY_POS, MODE_TRADES );
            if( OrderSymbol() == Symbol()
             && OrderMagicNumber() == ute_MagicID )
               {
                if (OrderType() == OP_BUY &&   (  diff_low_1_0 > 15*Point
                                              
                                                )
                                               )
               
                                             
                      {
                    
                       if(OrderClose(OrderTicket(),ute_lot,OrderClosePrice(),3,Red))
                         num_ordini_buy = 0;
                         else(Print("ERR.BUY CLOSE"));
                    
                       }  }
               

[Konstantin Nikitin]

OrderSelect( i, SELECT_BY_POS, MODE_TRADES );

if( !OrderSelect( i, SELECT_BY_POS, MODE_TRADES ) ) continue;

OrderSelect

for( int i = 0 ; i < OrdersTotal() ; i++ )

for( int i = OrdersTotal()-1 ; i >= 0 ; i-- )

OrderClose closes the order. This reduces the array. Therefore, the search from the senior to the younger.
