Please show the code how you create an indicator in your Expert Advisor.

In mql4 the information from the indicators on index zero in the tester gave a flipper date from the history. Have you had to ibarshift the same in mql5?

Rephrase. Put punctuation marks. Write in Russian.

Show the code how you create the indicator in the EA.

#include <Indicators\Trend.mqh>
#include <Indicators\Oscilators.mqh>
#include <Indicators\TimeSeries.mqh>

MqlTick infotick;
MqlDateTime currentTime;
CiMA ValueofMA200;
CiMA ValueofMA20;
CiMA ValueofMAHour;
CiATR atr;
CiTime timeh1;
CiTime timeD1;


   sym=_Symbol;
   ValueofMA200.Create(sym,PERIOD_D1,slowma,0,MODE_SMA,PRICE_CLOSE);
   ValueofMA20.Create(sym,PERIOD_D1,fastwma,0,MODE_SMA,PRICE_CLOSE);
   ValueofMAHour.Create(sym,PERIOD_H1,mahours,0,MODE_SMA,PRICE_CLOSE);
   atr.Create(sym,PERIOD_H1,200);
   timeh1.Create(sym,PERIOD_H1);
   timeD1.Create(sym,PERIOD_H1);
   
   timeh1.BufferResize(25);
   timeD1.BufferResize(200);
   
   timeh1.Refresh(PERIOD_H1);

Yes, if you use the standard library class to create indicators, then you must useRefresh methods to retrieve the data

How do these methods work? What is better to use?

RefreshCurrent
Refresh

I understandRefreshCurrent is a costly method on every tick.

1) How do these methods work? 2) Which is better to use?

1) Navigate to this method in the editor (middle-clicking on the method name will jump you to this method) - this will show you HOW the method works. The recipe is universal: middle-clicking on any method or function will jump to the function or method code itself.

2) There is no two ways about it. Some people use creation of indicators through classes, others use creation of handles (iMA, iMACD ...).

My mouse doesn't have middle button, it's made of pure silver)).Probably my problems with optimal calling have already been solved over the years. I wouldn't want to update the whole array with every tick.
