How to load more historical bars of custom symbol in metatrader 5?

greeting fellow trader, I have made my US dollas index symbol in MT5 and I try to request historical bars from 1980 until present but the requested bars only calculated from 2020 to present. What I need to do to get more historical bars of custom symbol from MT5 server?

Look for a data provider that offers such prices and build your custom symbol from that source.
