Good afternoon, is it possible to change the standard graphical tool in any way? More specifically: add a vertical line to the Fibo grid, plotted at a factor of 1.3

 

a question about the use of indicators. I wrote a test code.

int Fractals;
double bar_val[];
bool start;
int OnInit()
{
   Fractals = iFractals(_Symbol, _Period);
   if (Fractals == INVALID_HANDLE) return (1);
   if (!ArrayResize(bar_val, 2)) return (1);
   if (!ArraySetAsSeries(bar_val, true)) return (1);
   start = false;
   return(0);
}

void OnTick()
{
   if (start) return; else start = true;
   for (int i = 0; i < 10; i++)
   {
      CopyBuffer(Fractals, UPPER_LINE, i, 2, bar_val);
      if (EMPTY_VALUE != bar_val[0])
         Print("1. i = " + string(i) + ", bar_val = " + string(bar_val[0]));
      CopyBuffer(Fractals, LOWER_LINE, i, 2, bar_val);
      if (EMPTY_VALUE != bar_val[0])
         Print("2. i = " + string(i) + ", bar_val = " + string(bar_val[0]));
   }
}

It periodically displays fractal with i = 2, but it is not present on the screen (from the standard indicator Fractals)

Please advise what is the error

 
For some reason, between 2001 and 2006 no experts are being tested. I looked at the euro and the pound. Closed the terminal, deleted the history. Downloaded it again. All the same. It is possible to open deals till 2001. And from 2001 to 2006 it skips when there are signals. Why?
 

The timeframe buttons on the terminal bar are stuck. Sometimes several of them at once when frequently switching from one TF to another. Perhaps, it is due to a large number of windows, indicators, templates... However, I used to have as many windows as I did but this effect was not observed. The screenshot is an example of inconsistency between the timeframe button pressed and the real value shown in the upper left corner of the chart. More of a long term effect, although it does come off sooner or later.

Sometimes none is pressed at all.

 

Can I control the size of the window using mql5?

You should not know the exact code of the Expert Advisor at a glance

Additional information. This only happens if you selected D1 timeframe in the tester settings. If I select timeframe D1 in the Expert Advisor's settings and a smaller TF in the tester's settings, then there will be no skipping. Is this a bug or is there some explanation?
 

I made a simple indicator, but I don't understand why it doesn't want to work;(

Why does it not want to divide one by the other and show the result?

Sometimes it gives a result, but it doesn't correspond to reality, for example EURUSD should have a value within 300-400 on the clock...

close[i] when I substitute it, SmoothSpreadBuffer[i] when I substitute it, why does it not want to divide one by the other and show the result?

It's true, sometimes it gives a result, but it doesn't correspond to reality, for example, EURUSD clock should have a value in the range of 300-400...

UniPriceBuffer[i]=close[i]/SmoothSpreadBuffer[i];

Just substitute EURUSD values here for the current time and you'll get it:

Ma for example with an average of 16 at closing prices

UniPriceBuffer[i] = 1,33846 / 1.33932 = 0,99935

or better to use

handle=iMA(name,period,ma_period,ma_shift,ma_method,applied_price);

After the last build, the terminal hangs on loading. There is no access to the menu or the context menu. No access to menu or context menu. WIn7. Symbols overview window is empty. Connection icon is red. No CPU load. What to do and when will stability be available?
