How can I read iMA values in real time?

[Marco Tonchella]

I want use different iMAs and then I want read iMAs values.

The results is very different values (see chart).

How can I read the previous and last data?

Thanks.

I found the official CopyBuffer() documentation but I do not understand exactly how to use it.
https://www.mql5.com/en/docs/series/copybuffer

"starting position is performed from the present to the past"

So my buffer[0] is in real time when OnTick() and buffer[1] is the previous moment?
But my code does not seem to work very well, I just do not understand what I'm doing wrong.

Thank you.

copy to an target array;

  double    buffer[]              // target array to copy 

Call by the first position and the number of required elements

int  CopyBuffer(     int       indicator_handle,     // indicator handle     int       buffer_num,           // indicator buffer number     int       start_pos,            // start position     int       count,                // amount to copy     double    buffer[]              // target array to copy     );

Call by the start date and the number of required elements

int  CopyBuffer(     int       indicator_handle,     // indicator handle     int       buffer_num,           // indicator buffer number     datetime  start_time,           // start date and time     int       count,                // amount to copy     double    buffer[]              // target array to copy     );

Call by the start and end dates of a required time interval

int  CopyBuffer(     int       indicator_handle,     // indicator handle     int       buffer_num,           // indicator buffer number     datetime  start_time,           // start date and time     datetime  stop_time,            // end date and time     double    buffer[]              // target array to copy     );

Ok, thank you.

I read value but when I print buffer[0] and buffer[1] they are very different from the last value... 

Do you try my code?

Where am I doing wrong?

Thank you for your time.

You need to set the Array series direction to true.

ArraySetAsSeries(buffer,true);

...just a friendly tip... the MQL standard library is what you should first look to for some pretty cool and time saving code. Here is an example of what you need using the CiMA class.

#property indicator_chart_window

#include <Indicators\Trend.mqh>
CiMA g_ma55;

int OnInit()
{
   if(!g_ma55.Create(_Symbol,_Period,55,0,MODE_SMA,PRICE_CLOSE))
      return INIT_FAILED;
   g_ma55.Redrawer(true);
   return(INIT_SUCCEEDED);
}
//+------------------------------------------------------------------+
int OnCalculate(const int rates_total,
                const int prev_calculated,
                const int begin,
                const double &price[])
{
   g_ma55.Refresh();
   printf("Current = %f, Previous = %f",g_ma55.Main(0),g_ma55.Main(1));
   return(rates_total);
}

Ok very, very, thanks Nicholishen.
Your post is very intersting.

For the use OOP I'm reading this:
https://www.mql5.com/en/articles/100
https://www.mql5.com/en/docs/standardlibrary/expertclasses/expertbaseclasses/cexpert

In fact, after these tests I thought I would better study the standard library and the CExpert base class.

I understand that CExpert can be derived by creating a new class in which, by implementing virtual methods, you get an EA complete with indicators, money manager and methods for order execution according to the logic that we can implement.

Are there any suggestions or articles to follow for those who start?

The official documentation, albeit good, is lacking in my opinion, not have more/sufficient examples.

Fortunately there are you guys: D: D

I tried this but i am not getting exact moving average values of any timeframe it displays some random values near to moving average values but not the same moving average value. Can you please tell me how can i get the exact moving average values in specific time frame. Thank you in advance.

Show the code that you are using or nobody can help you.
