Why do I need the “Download data” button in the MoonBot terminal in the BackTest window in the “Exchange Archives” area?

: Interface configuration

The MoonBot terminal has a “BackTest” function – testing strategies based on historical trade data. On the main window of the MoonBot terminal, click on “Menu – BackTest”, the “BackTest” window will open. In the “Exchange archives” area of this window, after clicking the “Download data” button, the download of historical data with trades on the selected coin, exchange for the above dates will begin.
