I would like to make a sampling on a whole bunch of muwings on the rts futures. although I would also like to do it on muwings (the whole crowd and on different timeframes) and on sipi/show/euro-dollar

if you do not mind to make an example - i would appreciate it - i need to learn

The script creates a file in the experts\files folder. The file name is formed from symbol and current timeframe.

Saves in the file time, bar close price and values of the set mask

If I may Vinin, one more question (not too distracting from the table?!)

Vinin hello, can I ask you a question?

Advise code to calculate the correlation. A search returned a lot of results, but which code actually works is not clear.

You have corrected the indicator. It's good, it's fine. But there is an unclear point, with the trading condition? Please explain...

int start()
  {
   int    counted_bars=IndicatorCounted();
   int limit = Bars- counted_bars-1;
   
   for(int i = limit; i>= 0; i--) {
      ExtMapBuffer2[ i] = EMPTY;
      ExtMapBuffer1[ i] = EMPTY;
      MACD[ i]=iMACD(NULL,0, Fast_EMA, Slow_EMA,1,PRICE_CLOSE,MODE_MAIN, i);
      if ( MACD[ i] * MACD[ i+1]<0) {
         if( MACD[ i] < 0) ExtMapBuffer2[ i] = High[ i]+iATR(Symbol(), 0, 14, i);
         if( MACD[ i] > 0) ExtMapBuffer1[ i] = Low[ i] -iATR(Symbol(), 0, 14, i); 
      }
   }
   return(0);
}

my skis aren't going ?!

double a = MathExp(10), b = MathExp(-10);
	
	Print( a);
	Print( b);
	b = 1./ a;
	Print( b);

why b is 0 in both cases ?

although it should be something like this

4189,448798029520479024881126433

2,3869488522460123706406991425885e-4

2,3869488522460123706406991425885e-4

ah... that's a lot of decimal places...

I'm not quite clear about the trading conditions. I just sped up the indicator a bit.

The signals remain the same.

Why is b equal to 0 in both cases?

It's not zero. Print() prints out values to 4 digits. Use DoubleToStr(). By setting the required precision of course.
