Need help to understand this please

[Michael-M]

I need some advice for the below code if you please,

Period_MA is an external variable and I set it to 20, but when I am testing my code by changing

for(x=i; x<i+Period_MA; x++)

to

for(x=i; x<=i+Period_MA; x++)

the moving average disappear from the chart

   int Counted_Bars = IndicatorCounted();
   int Uncounted_Bars = Bars - Counted_Bars;
   Uncounted_Bars++;
 
   for(int i=0; i<=Uncounted_Bars; i++)
     {
      double Total = 0;
         for(x=i; x<i+Period_MA; x++)
           {
            Total = Total + iClose(NULL,0,x);
           }
 
       Closing_Price_Array[i] = Total / Period_MA;
     }

Noting that when I add the equal sign to the previously stated line of code , I get the moving average to widen like below, so I just need to know how it was calculated just by adding an equal sign so that will be the outcome

Thank you

For some reason when I save the post the code appear incomplete

any advice!

You need to set the code language to MQL4/MQL5 for it to display without issues.

Why do you use iClose instead of Close? The latter is much faster.

I don't know why you are experiencing this issue, but if you shared the .mq4 file, I could probably check it.

Here is the Mq4 file

And thank you so much for your support, next time I will choose the language while I insert the code

 

[Michael-M]

just incase the code should be

for(x=i;x<i+Period_MA; x++)

But I am trying to understand how an equal sign could make that difference, how it has been calculated

When you use the "strict less" (<), the moving average doesn't disappear - it tracks the Close price rather closely. When you change it to "less or equal" (<=), the MA gets moved up because your sum (Total) increases by one more Close value but you continue to divide it by the unchanged Period_MA. For example, if Period_MA = 11, you sum 12 values of Close and then divide it by 11.

Yes, you are right but isn't the variance that this one candle has affected the moving average huge!
