Problem with MultiTimeFrame chart series

 

Hi, I am new in  MQL. I want to get two MA indicator on one chart with different time frame, but then I set up  iMA() with different time frame (H1->H4)  I get empty chart without error messages.  Maybe someone can help me and say that I am doing wrong.

 iMA function do not recalculate close price buffer? So if I want to get result as in "tradingview" test case I have to calculate avg of last interval or resize the array and copy paste same candle values?    Maybe you now berter way how to get this result?
