1. Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?
             General rules and best pratices of the Forum. - General - MQL5 programming forum?
   Next time, post in the correct place. The moderators will likely move this thread there soon.

2. History tab → Right Click → choose.

If it does not help so ask your broker for support.
Because the brokers are archiving the data from time to time.
