Corrected in all these functions

Among the hotkeys is this

Общие действия в платформе

Hotkeys	Description
Alt+A	Copy to clipboard all results of testing or optimizing of Expert Advisor.

No luck to test its action.

Unfortunately, I have not found a key to enable/disable the display of trading levels. Because of them I can't see the comment to the chart when I need it.

fxsaber:.

Unfortunately, I couldn't find a key to show trading levels on/off. They make it impossible to see the chart commentary when needed.

I'm talking specifically about hotkeys. There's also OHLC for the grid.

In mt 4, in the help

SYMBOL_TRADE_CALC_MODE

Mode of contract cost calculation

int

That's all, guess ...

In Mt 5 in the help

SYMBOL_TRADE_CALC_MODE

Mode of contract cost calculation

ENUM_SYMBOL_CALC_MODE

There is a description of what is what.

Same as in mt 4 in the help

SYMBOL_SWAP_MODE

Swap calculation model

int

Question:

Is there a script somewhere to sort the characters in Market Watch?

I think it will help:

How do I notify the user when an EA has stopped?

#property strict

bool f()
{
  int Array[];
  
  Array[0] = 0; // array out of range
  
  return(false);
}

bool PrintError()
{
  Print(GetLastError());
  
  return(true);
}

bool Init = f() || PrintError();

void OnDeinit( const int Reason )
{ 
  Print(Reason);
}

In this sense MT4 was much wiser than MT5 - there was no program crash and you could analyse the LastError.
