For beginners, this article is sufficient to illustrate the use of indicators.

[Григорий Муратов]

Could you please tell me how in an indicator, for example, in the

Bands_handle=iBands(NULL,0,144,0,2,PRICE_CLOSE);

change PRICE_CLOSE to the value of "previous indicator", which is written manually.
In the terminal it can be selected, but how to write in the code, I do not understand.
The manual says that Handle is needed, but I only have a buffer.
Please help.

Check out the article https://www.mql5.com/ru/articles/15

Thanks for the link, however it claims in the comments there that the code is out of date. I'll try to look into it

Подскажите пожалуйста, как в индикаторе, например в

If you look at the documentation https://www.mql5.com/ru/docs/indicators/ibands -- the specification reads:

int  iBands(
   string              symbol,            // character name
   ENUM_TIMEFRAMES     period,            // period
   int                 bands_period,      // period for calculating the average line
   int                 bands_shift,       // indicator offset horizontally
   double              deviation,         // number of standard deviations
   ENUM_APPLIED_PRICE  applied_price      // price type or handle
   );

-- "price type or handle" -- here instead of PRICE_CLOSE you can write the handle of a custom indicator.

For example:

MA_Custom_handle=iCustom(NULL,0,"Examples\\Custom Moving Average",
                     MA_Period,
                     MA_Shift,
                     MA_Method,
                     PRICE_CLOSE
                     );
Bands_handle=iBands(NULL,0,144,0,2, MA_Custom_handle );
