mql5:
If 1.016134511377497e-297 is written as a fraction, it looks like this

1.01613~
________
    297
  10

If the accuracy in _Digits (e.g. 5 digits) is zero

Sorry to be intrusive, but how can this problem be solved?

You have latest_price.ask not initialised or not calculated correctly.
Without the source code it is impossible to determine.

MqlTick latest_price; // To be used for current quotes

MqlTradeRequest mrequest; // To be used for sending trade requests

MqlTradeResult mresult; // To be used for obtaining results of trade requests execution

MqlRates mrate[]; // Will contain prices, volumes and spreads for each bar

The matter is that I use the code from a sample file and change only deal conditions and indicators used. It worked fine before.

You'd better contact the desk service(link), with the source code attached, and we'll check it out.

And try to initialise all variables of structure type. For example, using ZeroMemory() function. And since some time it turned out that reference materials suffer from such a defect as absence of lines with initialization of variables of structure type.

Ratio of points (on price scale) to bars (on time scale).

Figured it out, thanks.

How about this?

Example:

void OnTick()
  {
   MqlTick last_tick;
//---
   if(SymbolInfoTick(Symbol(),last_tick))
     {
      Print(last_tick.time,": Bid = ",last_tick.bid,
            " Ask = ",last_tick.ask,"  Volume = ",last_tick.volume);
     }
   else Print("SymbolInfoTick() failed, error = ",GetLastError());
//---
  }

Hello, I forgot the name of my MT5 MQL cloud account. Does it coincide with my login? If not, where can I find it out?

Does it match my username? If not, where can I find it out?

Yes, it does.

Good afternoon. There is such a phenomenon as a distortion of the last bits in double, please advise what conditions need to be created for such a distortion to occur? Is distortion possible in operations = ? Is distortion possible when storing integers in double? While performing operations?
