All of the above does the code, except for the yellow highlighted - I think it's unnecessary and not quite correct. I've never seen anyone rollover at a different time, always at the same time - 22-00 GMT, although I could be wrong.

But often seen different duration rollover, some 5 minutes, and others a little over a minute.

Check code, maybe change something:

So and tie everything to GMT time. Got the difference of local time and server time, and you can immediately understand in how many rollover. And 5 minutes or 1 I think there is no significant difference. Take 5 minutes for all.

How is your option better or more reliable?

If you can, show me the code!
 
Vitaly Muzichenko:

Maybe not at all. I didn't follow your codes. Just giving my opinion.

 

Vitaly Muzichenko:

Are you pretending?

 
Alexey Viktorov:

Maybe it's nothing. I haven't been following your codes. Just giving my opinion.

Here's everything in one post:

You need to screen out the spread entry during the rollover so that the EA doesn't trade on the extended spread.

I have never encountered such a code before. Somehow never seen that rollover was someone at a different time, always all in one and the same - at 22-00 GMT, although I can be wrong.

But often seen different duration rollover, some 5 minutes, and others a little over a minute.

Check code, maybe change something:

//+------------------------------------------------------------------+
void OnTick(void)
{
   int sp = SymbolInfoInteger(Symbol(),SYMBOL_SPREAD);
   static int ts=0;

   if(CheckSpr(sp)) {
      // Здесь код отправки
      Comment( sp,"=",ts++,"=",res );
   } else Comment( "false: ",sp,"=",ts++,"=",res );
}

//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
MqlDateTime dt;
int res=0;
bool CheckSpr(int _sp)
{
  TimeGMT(dt);
  static int ts=0;
  static long tc=0;
   if(dt.hour==22) return(false); // ролловер
   tc++;
   ts += _sp;
   res =ts/tc;
   if(tc>LONG_MAX-1) {
      tc=0;
      ts=0;
   }
   // Comment( res,"=",tc );
   if(tc<500) return(false); // собираем спред на 500 тиках
   return(res>_sp?true:false);
}

Here's everything in one message:

We need to weed out the spread entry during the rollover so that the EA doesn't trade on the extended spread.


No trading during a full hour?

   if(dt.hour==22) return(false); // ролловер

Or did you misunderstand something?

are we just hypothetically prohibiting some kind of spread record (file, database) specifically in the rollover?

 
Alexey Viktorov:

No trade for a whole hour?

Or did you misunderstand something?

That's right, for a full hour afterwards, the spread is widened. And before the rollover in 5 minutes it is widened in some places as well.

However, it can be set like this:

void OnTick(void)
{
   int sp = SymbolInfoInteger(Symbol(),SYMBOL_SPREAD);

   if(CheckSpr(sp)) {
      // Здесь код отправки
      Comment( sp,"=",res );
   } else Comment( "false: ",sp,"=",res );
}

//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
MqlDateTime dt;
int res=0;
bool CheckSpr(int _sp)
{
  static int ts=0;
  static long tc=0;
  TimeGMT(dt);
   if(dt.hour==22 && res<_sp) return(false); // Если 1 час после ролловера спред упадёт до нормального - торгуем
   tc++;
   ts += _sp;
   res =ts/tc;
   if(tc>LONG_MAX-1) {
      tc=0;
      ts=0;
   }
   if(tc<500) return(false);
   return(res>_sp?true:false);
}

This should work correctly.

 
Vitaly Muzichenko:

You could, however, prescribe it this way:

That should work.

Funny) It shouldn't)

If the battle is for - trade with a normal spread, just put its "limit" in input and just ignore the trade if the spread is above the limit.

Spreads can be stretched by dillings without rollover.
