After downloading history data, when we press refresh button, journal displays a message "xxx" bars downloaded.

Can anyone explain what is happening behind the scene? Does it mean that history data had gaps and refresh button brings in additional data

to fill in the gap? And if so where that is coming from?

The earliest bar to the latest (minimum 2K bars,) from your broker, replaces any bars in that range. It means nothing more.

My broker is oanda.com (usa). At least once a week I have to do refresh to make sure that data is up-to-date when backtesting. With other brokers that I used before this did not happen.

Unless the current chart is the specific pair/TF referenced, you must handle 4066/4073 errors.
