Y(n+1)=(Y(n)*n+x[n+1])/(n+1), where Y(i) is the moving average of the i values, x[i] is the value numbered i. Numbering of values as in timeseries.

You'll be very obliged if you'll ever tell me why you need all this.

void CalculateSimpleMA(int rates_total,int prev_calculated,const double &price[])

      limit=InpMAPeriod;
      //--- calculate first visible value

         firstValue+=price[i];
      firstValue/=InpMAPeriod;

      ExtLineBufferFid[limit]=(firstValue*InpMAPeriod+price[i+1])/InpMAPeriod;

     }

Thank you for your feedback. The method of tendential planimetry

InpMAPeriod = 13;

Result: the current price of 1.09 calculates 1.27

The period 13 to the price of 1.09 does not equal 1.27, what am I doing wrong?

Is this a trending planimetric method? Maybetrending, in Russian?!

Who breaks like that? You have to bang it against your knee ;)

And do it like this:

Thanks for the answer, I found it in the tutorial myself, only it still doesn't write. And where am I supposed to see the message if there is no location?

Haven't found it in the tutorial yet ( or missed it ). And in passing, please: I don't understand the difference between Print and Alert.

Can you tell me?

Thank you.

Thank you.

Print() prints the message in the "Experts" journal if you are in demo or real mode, if you are in visualization mode, it prints it in the "Journal" of the tester

Alert() prints the message window on the chart, if it is in demo or real mode, if it is in visualization mode in the Visualization mode, then in the "Journal" log of the Strategy Tester.

1.(firstValue*InpMAPeriod+price[i+1])/InpMAPeriod;

2.(firstValue*InpMAPeriod+price[InpMAPeriod+1])/(InpMAPeriod+1);

The moving average can also be calculated a bit faster, since there are so many of them to be processed. Y[i]=Y[i+1]+(X[0]-X[N])/N

 

Hello. I have more than ten charts open in the window. I have one Expert Advisor active in all of them. How do I know the symbol of the chart that is currently active.

Symbol

Returns a text string with the name of the current financial instrument.

stringSymbol();


If I understand it correctly, it returns the symbol of the window, to which the Expert Advisor is attached. I need the symbol of the currently active window, how can I get it?

In which window do you have a lot of open charts?
 

I do not understand the question, in the program window

I need to know the symbol of the active chart. In the picture it is GBPUSD. How can I do it?

I need a function that will return GBPUSD to each open Expert Advisor in this example, regardless of the symbol.

The programme window is called the terminal. There are graphs (tools) in the terminal. Each chart (tool) can have several windows. What do you mean by all of this?
