mql4 change timeframe or symbol

[[Deleted]]

Is it possible to change the actual timeframe/symbol, or to read candleinfo from another timeframe/symbol ?

Yes, Something like this

double Roof_C=iCustom("EURUSD",PERIOD_M5,"Cog",3,0);

or

  Peak=iHigh("EURUSD",PERIOD_M5,
    iHighest("EURUSD",PERIOD_M5,MODE_HIGH,SR_Zone,1)
  );
