Do you have it in the editor in the folder Examples or in a similar meaning (from a mobile I can not see)

Please advise a novice programmer why I can change a parameter in the input parameters menu the first time I run the EA and it will work, but the next time I change this parameter, it does not work anymore. Initially it is TRUE, at first start I set False - comment does not show (as it should be), then I set True - comment appears, but if I want to remove it again, it is not removed.

extern bool displayShow = TRUE;

int start () {
        if(displayShow) {
                Comment ( "____12454");
        }
}

You forget to remove the comment from the chart: Comment("");

Вы забываете удалить комментарий с графика: Comment("");

Oh, right! Thank you!

Hello, could you please tell me how to set the profit in pips in the script?

Only double can be passed to iCustom via buffer. What is the best way to prepare for transferring datetime through iCustom?

I have done so so far:

OutputBuffer1[7]=(int)Time[i];
=========================================

double Output2=iCustom(...

datetime PerfTime=(datetime)(int)Output2;

If there are better options, then suggest it.

void              EveryTick(const bool);



//+------------------------------------------------------------------+

//|                                                                  |
//+------------------------------------------------------------------+
CExpertAdvisorBase::EveryTick(const bool value)
  {
   m_every_tick=value;
  }

Is this announcement correct or not? In MT4 and in MT5.

'EveryTick' - function already defined and has different type

I couldn't find in the search engine what does a two-dimensional array that is already filled look like? If a one-dimensional array can be written as Test={2,5,3} How would a two-dimensional array Test[][2] look like, for example 2,5,3 in the first array and 7,8,9 in the second array?
