why? 

Visually i see in tester the is rsi price are normal and moving, the rsi is changing. What can be the problem?

 
Put the cursor on iRSI and press F1 and read how this function is used! It returns a handle not values!
 

Hi

Exactly – int mt5 functions for indicators returns handles you should call this function in OnInit and then use CopyBuffer to get the values from this handle like this: 

double values[1];
int copied = CopyBuffer(rsi,0,0,1,values);

Print(“Current RSI: “, values[0]);

Have a nice weekend👍📊
