No.

Unfortunately I only have half a gig of traffic left until 2pm on 14.09 so I won't look. I'll look after that time. That's something...

 
Реter Konow:

Thank you, Nikolai - thanks to you I learned how much I gained from not having a clue about the debugger.

If I had relied on it, I would have nothing now. Maybe I would have, but half as much.

Simply because I wouldn't have been able to use a colossal advantage to use my own language in programming.

Strange, because you know English much better than I do, although I live in Canada. Why not write long names in English? Except they won't be highlighted in red.

On every word in your mind (albeit unconsciously) translate?

The mother tongue is biologically ingrained in the brain. Understanding is the fastest possible. Alien language is always processed before it is understood.

Pure biology.

I understand my own code much faster using Russian than I would if I used English. I memorize it much better.

I understand my own code much faster using Russian than I would if I used English. I am much better at remembering it.

And try to do something with #define. I'm just not at my computer right now. Maybe you can somehow work with Russian variable names in the debugger, if you can't do without them.

It just so happens that I have never had English - not in school, not in a single institute, not in a second one. I still don't understand it by ear at all. I'm learning it myself, but my first attempts were long before I started programming. Annygdot " - How did you learn English so fast? - What's there to learn - they got all words from C++" - that's me.

And you know what? I've never had an anglophone in my life for some reason. So speak for yourself - don't generalize to everyone.

I have translated my solution code into English for the public's convenience.

I hope I didn't mix up anything.

Thank you, Nikolai - thanks to you I have learned how much I have gained from not having a clue about the debugger.

If I had relied on it, I would have nothing now. Maybe I would have, but half as much.

Simply because I wouldn't have been able to use a colossal advantage to use my own language in programming.

I'm pretty sure if I used such tools as OOP and debugger in my work, I would do everything much faster and of higher quality!
Too bad you don't realize that...

 
Реter Konow:

For the convenience of the public, I have translated my solution code into English.

I hope I didn't make a mistake.

Try it and see the result.

void Trading_on_new_bars_strategy()
{
  for(int a1 = 0; a1 < All_symbols; a1++)
   {
    string This_symbol    = Symbols[a1];
    //----------------------------------
    for(int a2 = 0; a2 < All_Timeframes; a2++)
      {
       bool   New_bar      = New_Bar_Events[a1][a2];
       int    This_timeframe = Timeframes[a2];
       //----------------------------------
       if(New_bar && This_symbol == "EURUSD" && This_timeframe == PERIOD_M5)
         {
          //Buy();
          Print("M5");
         }
       //---------------------------------- 
       if(New_bar && This_symbol == "AUDUSD" && This_timeframe == PERIOD_M1)
         {
          //Sell();
          Print("M1");
         }
       //----------------------------------        
      }
   }
}

I won't argue. Time and practice will show whether I have chosen the right way, approach and tools.

 
Vitaly Muzichenko:

Try a print and see the results

What are your results?

Where are you calling the function from?
