Historic data import F2

 

I'd be most grateful if someone could an answer to a question which is eluding me.

I have two sets of historic data from separate sources for the same currency pair.  As we all know, all data sets have gaps.

If I import first one then the other will I have fewer gaps, or will the import of the second simply overwrite the first?

Many thanks. 

 
The second would simply overwrite the first. You'll be better off looking for good quality data and/or live with the realistic gaps.
