history synchronization question

 

I am back testing a multi currency EA. I noticed in my logs there are messages such as:

2015.04.23 19:00:17    Core 8    GBPCAD: history for 2015 year synchronized

What exactly does history synchronization do? I see it happening on pairs that are included in my EA but set to "false", meaning that they do not trade but the history is still being synchronized.

The Strategy Tester can "see" which symbols are defined in your EA, but it can't "see" that such symbol is set to false. It synchronized data for all symbols which might be used.
