I want to fully learn C++. But, as I understand it, Visual Studio has its own standards (sort of by standards), but some resources say that it's better not to use their development environment, but use gcc to compile and something to write source code (for example, eclipse for this case I'm looking at).

What would you advise? Learn from Visual?

There's nothing more convenient thanVisual Studio. And Stroustrup's tutorial.

Straustrup, in my opinion, writes very dryly. Or maybe it's the translation ("C++ programming language. Special edition")... All in all, it's very soporific. It'll be hard :)

I would like to be able to limit the number of bars for calculation in MT4 indicator. I have guessed that such a line should be added.

extern int BarsCount = 50;

And if BarsCount = 0, it should calculate all the bars.

But it is difficult to go further. I think some changes should be made in this block, but I am not sure which ones. Please advise me, if it's not too difficult.

int start() 
{
   int counted_bars = IndicatorCounted();
   if (counted_bars < 0)
      return (-1);
   if (Bars <= LPeriod + Filter + 2)
      return (0);
   int limit = Bars - counted_bars - 1;
   if (limit > Bars - (LPeriod + Filter + 1))
      limit = Bars - (LPeriod + Filter + 1);
   for (int i = limit; i >= 0; i--)
       GlCalcul(i);
   return (0);
}

Colleagues - please comment... my question as far as the answer is concerned...

Roman, tried to understand, but failed a little, try to reword it to be clearer and more unambiguous. and my questions a little earlier apparently no one here knows(

That's right! I downloaded the Visual Studio manual from Microsoft... 14,000 pages... o_o

Does it matter which of these things to select, if the checkbox GENETICS is unchecked (here, this checkbox is hidden behind the drop-down list), because when unchecked - ALL values of optimized parameters will be passed anyway?

It doesn't. The results will be obtained for all combinations of EA's parameters. And you can sort them any way you want.
